International Investment Agreements (IIAs): Frequently Asked Questions

Summary
In recent decades, the United States has entered into binding investment agreements with foreign
countries to facilitate investment flows, reduce restrictions on foreign investment and expand
market access, and enhance investor protections, while balancing other policy interests. Some
World Trade Organization (WTO) agreements address investment issues in a limited manner. In
the absence of a comprehensive multilateral agreement, bilateral investment treaties (BITs) and
investment chapters in free trade agreements (FTAs), known as international investment
agreements (IIAs), have been the primary tools for promoting and protecting international
investment.
This report answers frequently asked questions about U.S. IIAs including provisions for investor-
state dispute settlement.

International Investment Agreements (IIAs): Frequently Asked Questions

he United States is a major source and recipient of foreign direct investment (FDI). In
recent decades, the United States has entered into binding international investment
Tagreements (IIAs) with foreign countries to facilitate investment flows, reduce restrictions
on foreign investment, expand market access, and enhance investor protections, while balancing
other policy interests. Congress is active in developing and implementing U.S. policy on
protecting and promoting FDI, including through setting trade policy negotiating objectives in
Trade Promotion Authority (TPA) legislation, Senate ratification of bilateral investment treaties
(BITs); and congressional consideration of legislation to implement free trade agreements (FTAs).
Bicameral legislation to reauthorize TPA, the “Bipartisan Congressional Trade Priorities and
Accountability Act of 2015” (H.R. 1890/S. 995), was introduced in April 2015 and is currently
under consideration.
This report answers frequently asked questions about IIAs made between the United States and
other countries. Questions are categorized in three main areas: (1) background and context; (2)
U.S. international investment agreements; and (3) investor-state dispute settlement (ISDS). An
Appendix summarizes select ISDS cases.
Background and Context
What is foreign direct investment (FDI)?
Foreign direct investment (FDI) is a type of cross-border capital flow. It takes place when a
resident (including a company) of one country obtains a lasting interest in, and a degree of
influence over the management of, a business enterprise in another country. The United States
defines direct investment as the ownership of at least 10% of the voting securities of an
incorporated business enterprise or the equivalent interest in an unincorporated business
enterprise.1 The U.S. “international investment position” or “stock” of FDI is the cumulative
amount at a given point in time, while the flow of FDI measures its movement for a particular
period of time, such as for a year.
What is the composition and size of FDI?
In 2013, the total stock of global FDI surpassed $25 trillion, with the United States continuing to
have the world’s largest cumulative share of FDI on a country basis ($4.9 trillion).2. Global FDI
inflows increased by 9% to reach nearly $1.5 trillion in 2013, though remaining below pre-2008
financial crisis levels (Figure 1).3 According to preliminary estimates, global FDI inflows
decreased to $1.26 trillion in 2014.4 Historically, developed countries have been the primary
sources of global direct investment. In recent years, emerging market and developing economies
have played an increasing role in global investment. In 2010, these economies accounted for the

more than 50% of global FDI inflows for the first time. While FDI generally has flowed from
capital-exporting, developed countries to developing countries, “South-South” investment flows
are growing. . FDI flows can fluctuate broadly on a year to year basis, associated with changes in
global economic conditions, the impact of certain business deals, and other factors. As such, the
U.S. position as the leading recipient of direct investment flows has been overtaken in some
years. According to preliminary estimates, in 2014, the U.S. position as a recipient of inward
direct investment dropped to third largest ($86 billion), after China ($128 billion) and Hong Kong
($111 billion).5

Pacific ranking as the first and second largest sources of inward U.S. FDI.

What is the relationship between international trade and
investment?

Investment is considered to be a major driver of trade. Economists generally believe that firms
invest abroad because those firms possess some special process or product knowledge or because
they possess special managerial abilities which given them an advantage over other firms.7 In
general, U.S. firms invest abroad to serve the foreign local market, rather than to produce goods
to export back to the United States, although some firms establish overseas operations to replace
U.S. exports or production, or to gain access to raw materials, less expensive labor, or other
markets.8 Foreign companies may choose to invest in the United States, for instance, to access
U.S. skills, resources, and the U.S. consumer market.9 Both U.S. inward and outward direct
investment play a role in U.S. trade, jobs, and production. In 2011, the affiliates of foreign firms

in the United States employed about 6.3 million workers, exported $343 billion in goods, and
imported $677 billion in goods.10
Investment gives rise to inter- and intra-firm trade, which represents trade between U.S. parent
companies and their foreign affiliates and U.S. affiliates of foreign firms and their foreign parent
company. The rapid pace of globalization in recent years has led to the creation of diverse
international supply and value chains, where goods are transformed from basic components to
end-use consumer products, often crossing the borders of multiple countries in the process. Thus,
for example, exports by U.S. parent companies to their foreign affiliates include not only exports
for resale without further manufacture, but also exports for further manufacturing.
U.S. Department of Commerce data indicate that the value of exports shipped by U.S. parent
companies was $738 billion in 2012, which accounted for 47% of total U.S. exports of $1.6
trillion. Similarly, the U.S. affiliates of foreign parent companies exported $334 billion in 2012,
or 21% of total U.S. exports. Also, U.S. parent companies accounted for 41% of U.S. imports, or
$ 949 billion, and the U.S. affiliates of foreign firms accounted for 29% of U.S. imports. Intra-
firm trade, or trade between parent companies and their affiliates accounted for 29% of total U.S.
goods exports and 34% of total U.S. goods imports. Intra-firm trade between U.S. parent firms
and their foreign affiliates accounted for 18% of U.S. exports and 13% of U.S. imports, while
trade between the U.S. affiliates of foreign firms and their foreign parent companies accounted
for 10% of U.S. exports and 21% of U.S. imports.11
What are international investment agreements (IIAs)?
IIAs broadly refer to agreements that establish binding rules on investment protections. U.S. IIAs
are reciprocal in nature; thus, in exchange for the specific protections that the United States offers
foreign investors in the United States, U.S. investors investing in IIA partner countries are
expected to receive the same protections. For the United States, the primary forms of IIAs are
bilateral investment treaties (BITs) and BIT-like investment chapters in regional and bilateral free
trade agreements (FTAs). Investment chapters in U.S. FTAs generally resemble investment
provisions in U.S. BITs. The major difference is that BITs, as their name indicates, focus on
investment issues, while FTAs are more comprehensive, encompassing a wide range of trade and
trade-related issues involving goods, services, agriculture, and investment.12
What types of barriers do investors face in foreign countries?
Barriers faced by investors in foreign countries include discriminatory and other restrictions on
foreign equity participation, forms of establishment, local content requirements, technology
transfer requirements, export performance requirements, and restrictions on repatriation of

earnings, capital, fees, and royalties, among other issues.13 Companies also can face barriers in a
foreign market’s operational environment. These barriers may include economic and political
instability; economic policies and measures that limit growth (such as capital controls, exchange
rate controls, tax and regulatory policies); expropriation and nationalization of private property;
weak, underdeveloped, or overly bureaucratic institutions; corruption and lack of transparency;
non-independent judicial systems, and limited infrastructure.14
What is the U.S. policy on IIAs?
The United States’ dual role as both a major source and recipient of direct investment shapes its
investment policy and generally supports an open investment climate consistent with national
security. The United States has pursued binding, reciprocal investment agreements with foreign
countries to facilitate investment flows, reduce restrictions on foreign investment, expand market
access, and enhance investor protections, while balancing other policy interests. U.S.
commitments in IIAs also provide national security exceptions.
In addition to negotiating IIAs, the United States conducts other activities related to facilitating
U.S. investment abroad. For example, the Overseas Private Investment Corporation (OPIC)
provides political risk insurance, financing, and other services to U.S. investors to mitigate the
risks of investing in developing and emerging countries.15 With respect to national security, the
interagency Committee on Foreign Investment in the United States (CFIUS) serves the President
by overseeing the national security implications of foreign investment in the economy by
reviewing proposed foreign investment transactions in the United States. The President has the
authority to block proposed or pending foreign investment transactions that threaten to impair the
national security.16
U.S. investment policy also includes a focus on attracting investment to the United States. In
2011, President Obama issued a statement reaffirming the United States’ “open investment
policy,” which is a “commitment to treat all investors in a fair and equitable manner under the
law.”17 The Department of Commerce’s SelectUSA program is intended to coordinate federal
efforts to attract and retain investment in the United States, complementing states’ investment
promotion activities.18

International Investment Agreements (IIAs): Frequently Asked Questions

What is the congressional role on IIAs?
The role of Congress on IIAs includes setting U.S. trade policy negotiating objectives on
investment19; Senate advice and consent on ratification of BITs; and congressional consideration
and passage of legislation to implement free trade agreements, which typically include an
investment chapter. Congressional prerogatives are present in the U.S. trade and investment
negotiating agenda. Presently, the United States is negotiating two mega-regional free trade
agreements—the Trans-Pacific Partnership (TPP) and the Transatlantic Trade and Investment
Partnership (T-TIP)—that would include investment provisions. Other U.S. engagement on
investment includes current BIT negotiations with China, India, Pakistan, and Mauritius, and
discussions with the East African Community (EAC—Kenya, Tanzania, Uganda, Rwanda, and
Burundi) over a possible regional BIT.20
Does Trade Promotion Authority (TPA) include investment
negotiating objectives?

Congress provides investment negotiating objectives in statutes granting the President Trade
Promotion Authority (TPA). The 2002 TPA (P.L. 107-210), which expired in 2007, included a
principal negotiating objective to “reduce or eliminate artificial or trade-distorting barriers to
foreign investment while ensuring that foreign investors in the United States are not accorded
greater substantive rights with respect to investment protections than United States investors in
the United States ... ” It also sought to “secure for investors important rights comparable to those
that would be available under United States legal principles and practice.... ”
Recently introduced bicameral legislation to reauthorize TPA, the “Bipartisan Congressional
Trade Priorities and Accountability Act of 2015” (H.R. 1890/S. 995) incorporates the investment
negotiating objectives of the 2002 TPA, as well as provisions in other negotiating objectives that
may affect investment.21 The 2002 TPA, the 2012 Model BIT, and the recently-introduced
legislation includes language advocating for a future multilateral appellate mechanism, which
could review awards rendered by investment arbitration tribunals.
Are there multilateral rules on investment in the World Trade
Organization (WTO)?

Presently, some World Trade Organization (WTO) agreements address investment issues in a
limited manner:
• The Trade-Related Investment Measures (TRIMS) Agreement includes
disciplines on WTO member countries applying restrictive investment measures

that are inconsistent with national treatment obligations (such as performance
requirements22) under the General Agreement on Tariffs and Trade (GATT);
• The General Agreement on Trade in Services (GATS) includes investment
liberalization provisions related to trade in services; and
• The Agreement on Subsidies and Countervailing Measures (ASCM) and the
Government Procurement Agreement (GPA) deal indirectly with investment by
including several investment incentives in its definition of subsidies and public
procurement services, respectively.
Additionally, the Energy Charter Treaty, agreed to in 1994, covers investment in the energy sector
among its 51 member countries (the United States is not a member23). Over the past several
decades, efforts have been made through international organizations to develop investment rules
(see text box). In the absence of an overarching multilateral framework on investment,
investment flows largely are governed by bilateral and regional IIAs.
International Efforts to Develop Investment Rules
In contrast to other areas of policymaking such as international trade, there is no comprehensive agreement on
international rules for the promotion and protection of investment. The last major effort to develop a comprehensive
agreement on international rules on investment was through the Organization for Economic Cooperation and
Development (OECD). During the 1990s, developed countries in the OECD proposed a Multilateral Agreement on
Investment (MAI), which would have included provisions to liberalize and provide non-discriminatory treatment for
investment and provide a dispute settlement mechanism.24 The OECD negotiations ultimately were abandoned
following policy disagreements among participating countries, the business community, and nongovernmental
organizations.25
Some WTO members, particularly the European Union (EU) sought to include investment in the Doha Round of
WTO trade negotiations. The 2001 WTO Doha Declaration directed the WTO Working Group on the Relationship
between Trade and Investment to focus on several investment issues. However, debate over the inclusion of
investment issues (as well as trade and competition and procurement) in the negotiations led to their omission from
the WTO agenda at the 2003 WTO Ministerial Conference in Singapore. In addition, investment is covered by
several so-called “soft law” (non-binding) efforts such as the OECD’s Guidelines for Multinational Enterprises and the
OECD’s Code of Capital Movements.
How many IIAs exist globally and in the United States?
To date, around 3,200 international investment agreements have been concluded worldwide, of
which around 2,500 are in force).26 The first modern BIT, concluded in 1959, was between West
Germany and Pakistan. During that time, European countries, especially those lacking colonial
ties and informal networks in developing countries, began negotiating investment treaties to
safeguard their existing global investments and facilitate new investments in their former

certain benefits for their economies. They can include export requirements, local content requirements, restrictions on
domestic sales tied to export performance, technology transfer requirements, among other restrictions.

December 1991, it has not been ratified by the President.

colonies. By the mid-1960s, several European countries had initiated BIT programs. Asian
nations began to sign BITs in the 1970s; Japan signed its first BIT in 1977 with Egypt. The
United States subsequently initiated its BIT program in 1977. Following the fall of the Soviet
Union, Central and Eastern European countries began signing BITs in the late 1980s and 1990s,
and Latin American countries entered the arena in the 1990s.
The BIT network grew slowly over the first three decades. Initially, BITs were drafted by capital-
exporting states primarily to protect their investors from unfair foreign treatment. For developing
countries, there was a shared belief that BITs would increase foreign investment, spurring
economic growth. From the late 1980s through the mid-1990s, BITs proliferated rapidly, both
between developed and developing countries and between developing countries, as many
developing countries embraced the so-called “Washington Consensus” reforms of
macroeconomic discipline, market-based economies, and rules-based openness to trade and
foreign direct investment.

The United States has BITs in force with 40 countries, and 14 FTAs in force with 20 countries,
most with investment chapters (see Figure 4). While U.S. IIAs are a small fraction of the global
total, they are often viewed as more comprehensive and of a higher standard than those of other
countries. The U.S. Department of State and the Office of the U.S. Trade Representative (USTR)

co-lead the U.S. BIT program, in close coordination with other U.S. government agencies. The
USTR leads FTA negotiations, also in close coordination with other U.S. government agencies.
In contrast to the investment treaty programs of many other advanced economies, the U.S.
investment treaty program has focused on developing and emerging economies. All of the
individual U.S. BITs are with developing countries. The United States has FTAs (with investment
chapters) with six of its top twenty trading partners: Australia, Canada, Columbia, Mexico,
Singapore, and South Korea. The U.S.-Australia FTA’s investment chapter does not include
iinvestor-state dispute settlement.

Is the United States currently negotiating any IIAs?
Current U.S. investment negotiations center on two proposed mega-regional FTAs: the Trans-
Pacific Partnership (TPP) and the Transatlantic Trade and Investment Partnership (T-TIP), whose
participating countries represent around three-quarters of the stock of U.S. FDI abroad, but do not
include major emerging economies, such as China, India, and Brazil. The United States,
separately, is conducting BIT negotiations with China and India, which present both significant
market access opportunities and challenges. The United States has also started BIT negotiations
with Mauritius and Pakistan in recent years. Additionally, the United States is in discussions with
the East African Community (EAC—Kenya, Tanzania, Uganda, Rwanda, and Burundi) over a
possible regional BIT.

International Investment Agreements (IIAs): Frequently Asked Questions

Does the United States have a Model BIT?
The USTR and the State Department negotiate U.S. investment agreements on the basis of a
Model BIT text. The United States completed its original Model BIT in 1981, and it has been
revised several times, most substantively in 2004, and most recently in 2012. Prior to the 2004
changes, the United States negotiated BITs on a 1994 Model BIT based largely on the investment
chapter in the North American Free Trade Agreement (NAFTA). The 2004 Model BIT changes
primarily related to U.S. concerns that the types of protection granted to foreign investors by
NAFTA may have been written too broadly, and that foreign investors would possibly receive
more favorable treatment for their NAFTA-related investor-state dispute claims than U.S.
investors would under U.S. law.
To address these concerns, the U.S. government made several changes in the 2004 Model BIT in
order to give the BIT parties greater control over the arbitral process and to limit access to ISDS.
These changes were reaffirmed in recent agreements and the 2012 Model BIT.27 Post-NAFTA
U.S. investment provisions in BITs and FTAs incorporated a principal trade negotiating objective
from the 2002 Trade Promotion Authority stipulating that no trade agreement is to lead to foreign
investors in the United States being granted greater substantive rights than what are granted to
U.S. investors in the United States (see below section on core provisions). Additionally, the 2004
model and subsequent investment treaty chapters now provide more detailed guidance for both
parties and tribunals and also address procedural and other matters not included in earlier U.S.
investment treaties, such as the expedited review of claims, rules on frivolous claims, the
participation of non-disputing third parties in the arbitration, a statute of limitations, and the
consolidation of related claims. The 2012 Model BIT and recent FTAs also formalized the
transparency and openness of the arbitral proceedings. Presently, questions remain about further
revisions to the Model BIT, for instance, in terms of developing an appellate mechanism.28
How does the U.S. Model BIT define investment?
Since the beginning of the BIT program, the definition of investment in U.S. treaties has
expanded beyond traditional forms of investment, such as “physical” investments. It recognizes
that investment may take a variety of forms, including intangible investments such as intellectual
property rights but that not all assets are considered an investment. The 2012 Model BIT provides
the following definition of investment:
“investment” means every asset that an investor owns or controls, directly or indirectly, that
has the characteristics of an investment, including such characteristics as the commitment of
capital or other resources, the expectation of gain or profit, or the assumption of risk. Forms
that an investment may take include
(a) an enterprise;
(b) shares, stock, and other forms of equity participation in an enterprise;
(c) bonds, debentures, other debt instruments, and loans;

27 The text of the U.S. Model BIT is available at http://www.state.gov/documents/organization/188371.pdf.
28 The possible creation of an appellate mechanism was first identified as a negotiating objective in the 2002 TPA.

(h) other tangible or intangible, movable or immovable property, and related property rights,
such as leases, mortgages, liens, and pledges.
What are the U.S. Model BIT’s core provisions?
All U.S. IIAs are binding, reciprocal agreements. In addition to specific market access
commitments, U.S. international investment agreements typically include the following:
Nondiscriminatory treatment. Provides for the better of national treatment or most favored
nation treatment for the full life cycle of an investment (from its establishment or acquisition,
through its management, operation and expansion, to its disposition).
Minimum standard of treatment. Investment protections in accordance with customary
international law, including fair and equitable treatment and full protection and security.
Compensation for expropriation. Prompt, adequate, and effective compensation when direct or
indirect expropriation takes place (based on U.S. law); recognition that, except in rare
circumstances, non-discriminatory government regulation (e.g., public health, safety, or
environmental regulation) is not an indirect expropriation.
Transfer of funds. Timely transfer of funds into and out of the host country without delay using a
market rate of exchange.
Limits on performance requirements. Restrictions on trade-distorting performance
requirements (such as local content rules or export quotas).
Investor-State Dispute Settlement (ISDS). The right of an investor to submit an investment
dispute with the treaty partner’s government to binding, impartial international arbitration.
Other requirements and exceptions. Environmental, labor, transparency, and anti-bribery
requirements, as well as exceptions for national security and prudential interests and provisions to
prevent forum shopping.
These provisions are reflected in the 2015 bicameral TPA reauthorization legislation introduced in
the 114th Congress (H.R. 1890/S. 995).
What is Direct and Indirect Expropriation?
The 2012 Model BIT and other U.S. IIAs prohibit the expropriation of covered investments
except: (1) for a public purpose; (2) in a non-discriminatory manner; (3) upon payment of prompt,

adequate, and effective compensation; and (4) in accordance with due process of law and the
minimum standard of treatment.29 Direct expropriation of an investment occurs when the host
country deprives the investor of the value of its investment by, for example, transferring title in
the investment to the state.30 By contrast, an indirect expropriation occurs when the investor
retains title to the investment but cannot make economic use of the investment for a significant
period of time because, for example, of discriminatory government regulations that substantially
interfere with the investor’s use of the investment.31
Some observers raised concerns about early NAFTA decisions interpreting the legal standard for
indirect expropriation. To address concerns raised by these decisions, the 2012 Model BIT
contains an annex that specifically spells out the factors a tribunal must consider when
determining whether an indirect expropriation has occurred. These factors mirror those in the
U.S. Supreme Court decision in Penn Central, a case that determined the test for regulatory
takings under the Fifth Amendment of the U.S. Constitution. The factors consist of:
(i) the economic impact of the government action, although the fact that an action or series of
actions by a Party has an adverse effect on the economic value of an investment, standing
alone, does not establish that an indirect expropriation has occurred;
(ii) the extent to which the government action interferes with distinct, reasonable investment-
backed expectations; and
(iii) the character of the government action.32
Do U.S. IIAs prevent governments from taking regulatory action?
Recent U.S. IIAs, such as the investment chapter of the U.S.-South Korea FTA (KORUS), state
that nondiscriminatory regulatory measures generally do not result in indirect expropriation. For
example, the 2012 Model BIT states that “Except in rare circumstances, non-discriminatory
regulatory actions by a Party that are designed and applied to protect legitimate public welfare
objectives, such as public health, safety, and the environment, do not constitute indirect
expropriations.”33
Do U.S. IIAs provide greater rights to foreigners?
U.S. IIAs are binding reciprocal agreements and do not provide greater substantive rights to
foreign investors. Earlier concerns that foreign investors were receiving greater substantive rights

International Investment Agreements (IIAs): Frequently Asked Questions

under IIAs with ISDS provisions than U.S. investors obtained under U.S. law prompted Congress
to include a provision in the investment negotiating objectives in the 2002 TPA stating that the
investment protections in future IIAs should ensure that “foreign investors in the United States
are not accorded greater substantive rights with respect to investment protections than United
States investors in the United States.”
Some observers argue that the availability of ISDS itself implies greater procedural rights by
providing foreign investors in the United States with an additional choice of venue besides U.S.
courts. While this debate has focused on rights afforded to investors in the United States, it is
important to recognize that, under a U.S. investment agreement, a U.S. business investing in a
foreign country would have recourse to ISDS to resolve disputes with the host country’s
government. From the view of supporters, this access may be particularly important in situations
where judicial systems in foreign countries may not be fully formed or independent, or where
there may be significant corruption.
Investor-State Dispute Settlement
Procedures
What is Investor-State Dispute Settlement (ISDS)?
ISDS provisions in IIAs enable an aggrieved investor, with an investment located in the territory
of a foreign host government, to bring a claim against that government for breach of an
investment agreement before an international arbitration panel. ISDS provisions are intended to
establish a binding and impartial procedure for the settlement of investment disputes. Although
ISDS is a common part of the international investment architecture, its use is actively debated,
including in the current TPP and T-TIP negotiations.
What is the history of ISDS?
Historically, before the advent of ISDS, “unlawful behavior by States targeting foreign investors
tended either to go unaddressed or to escalate into conflict between States.”34 Further, “[m]ilitary
interventions in the early years of U.S. history—gunboat diplomacy—were often in defense of
private American commercial interests.”35 In the absence of ISDS, an investor whose property has
been expropriated, or otherwise injured by a foreign government, such as through discriminatory
action, also could either seek redress in the domestic courts of the foreign government or seek the
espousal of their claim by their investor’s home government through state-to-state dispute
settlement. From this perspective, ISDS represented a more peaceful, effective mechanism for
addressing disputes between investors and host countries.36 According to one of the framers of the
U.S. BIT program, the decision to include ISDS in U.S. investment treaties “was based on the
desire to provide investors with a stable and secure dispute settlement device and to de-politicize

investment disputes.”37 Predecessors to the contemporary form of ISDS date to the 1900s, with
arbitration institutions established in London, Stockholm, and Paris.38 States began to include
ISDS in their investment treaties in the late 1960s and early 1970s. By the 1990s, ISDS became a
standard element of international investment agreements.39
Under what rules are ISDS cases arbitrated?
Although an investor submitting a claim under a U.S. IIA must typically consent to the mandatory
substantive and procedural rules contained therein, the parties to an investment dispute generally
may jointly choose the forum as well as many of the procedural rules under which the tribunal
conducts the arbitration.40 Most international investor disputes are conducted under rules of the
1965 Convention on the Settlement of Investment Disputes between States and Nationals of Other
States
, which established the International Centre for Settlement of Investment Disputes
(ICSID).41 ICSID, an affiliate of the World Bank Group headquartered in Washington, DC,
provides arbitral services and rules for investment disputes to the 147 members who have ratified
the ICSID Convention. Investment arbitration tribunals (e.g., NAFTA Chapter 11 tribunals) may
use the facilities and rules provided by ICSID. A separate facility, the ICSID Additional Facility,
was created in 1978 to arbitrate disputes if either the home or host state, but not both, is not a
member of ICSID. The ICSID Additional Facility can also arbitrate non-investment disputes. The
most common alternative to ICSID is international arbitration under the rules established in the
United Nations Commission on International Trade Law (UNCITRAL).42 The
Who decides investment disputes?
The methods of selection and disqualification of arbitrators may differ depending on whether the
arbitration is conducted under ICSID or UNCITRAL Arbitration Rules, NAFTA, or agreements
based on the U.S. Model BIT. Furthermore, the parties may also contract to have the dispute
governed by rules other than the ICSID and UNCITRAL Arbitration Rules.
With regard to selection of arbitrators, both NAFTA and U.S. FTAs based on the recent Model
BIT state that, unless the parties otherwise agree, the tribunal shall be comprised of three
arbitrators. The claimant appoints one arbitrator; the respondent state appoints one arbitrator; and
the parties then agree on a presiding arbitrator. If the disputing parties cannot agree on
appointment of an arbitrator, then the Secretary-General of ICSID becomes the appointing
authority.

International Investment Agreements (IIAs): Frequently Asked Questions

Under the ICSID Convention, arbitrators must be “persons of high moral character and
recognized competence in the fields of law, commerce, industry or finance.”43 However, under the
UNCITRAL Arbitration Rules, there does not appear to be a corresponding provision that
explicitly requires arbitrators to be recognized as competent in any particular field.
Can arbitrators be disqualified for bias?
In the event that a party to the arbitration believes that an arbitrator should be disqualified, the
procedures it must follow depend on the rules that govern the arbitration. Under the ICSID
Convention and Arbitration Rules, a party may propose disqualification of an arbitrator on
account of any fact indicating that the arbitrator has a “manifest lack” of the ability to exercise
independent judgment. Similarly, under the UNCITRAL rules, an arbitrator may be challenged if
“circumstances exist that give rise to justifiable doubts as to the arbitrator’s impartiality or
independence.” Arbitrators have an obligation to affirmatively disclose such circumstances both
prior to, and during, the dispute proceedings.
What circumstances have led to an arbitrator being disqualified?
It appears that many challenges to an arbitrator’s qualifications to sit on a tribunal arise from prior
existing relationships between the arbitrators and the disputing parties. For example, one
arbitrator, in 2013, was disqualified from the tribunal in Blue Bank v. Venezuela because the
arbitrator in question was a partner at a law firm that was representing the claimant in a different
ISDS proceeding against Venezuela that dealt with issues similar to the case he was set to decide.
However, tribunals have also held that “the mere existence of some professional relationship with
a party is not an automatic basis for disqualification of an arbitrator.” In one case, the arbitrator in
question advised the disputing parties that one of the partners in his law firm had worked for the
claimant-company’s predecessor on an unrelated tax issue but the panel did not find this
relationship warranted disqualification.
Prior relationships with disputing parties are not the only reason that an arbitrator can be
disqualified. Arbitrators can also be removed from a panel if they have biases against the law in
dispute or the specific subject at issue. One such example, involving a successful challenge, came
when the United States, during a NAFTA arbitration conducted under the UNCITRAL Arbitration
Rules, challenged the appointment of an arbitrator who had previously given a speech on the U.S.
law at issue in the dispute. The arbitrator, in his speech, referred to the U.S. law in question as
“harassment.” The ICSID Secretary General, who was authorized to make the final determination
on the issue as the appointing authority, informed the arbitrator that ICSID would be issuing an
opinion upholding the challenge. In response, the arbitrator resigned and the ICSID did not issue
a written opinion on the matter.
How are claims brought?
Under U.S. IIAs, a claimant must follow several procedures in order to initiate an arbitration
proceeding. First, the claimant must attempt to resolve the dispute by consultations and
negotiations with the respondent state.44 The agreements generally contain a “cooling down

43 ICSID Convention, art. 14.

International Investment Agreements (IIAs): Frequently Asked Questions

period” of six months from the time the claim arose to the time that an investor may submit it to
arbitration.45 This is intended to give the investor and respondent state time to enter into
consultations and possibly negotiate a settlement. In addition, U.S. IIAs typically require the
claimant to provide 90-days’ written notice to the respondent state prior to submitting a claim to
arbitration, which includes, among other things, the legal and factual basis of its claim.46
When the investor submits the claim, they must consent in writing to the mandatory substantive
and procedural rules contained in the IIA under which the investor submits the claim.47 The
claimant investor (and, if applicable, the enterprise on behalf of which it submits the claim) must
also waive its rights to pursue monetary relief for its claim in domestic tribunals of parties to the
treaty or under other dispute settlement procedures.48 There is a three-year limitation period on
claims beginning on the date on which the claimant had actual or constructive knowledge of the
respondent state’s breach of the investment agreement, as well as knowledge that the claimant or
the relevant enterprise “incurred loss or damage.”49 The parties generally have a large amount of
discretion in jointly choosing the facilities at which the arbitration will be conducted as well as
many of the procedural rules that will govern the arbitration.50
In terms of investor eligibility to ISDS under an investment agreement, one issue is the amount of
business activity an investor would need to have in the host country in order to qualify. Under the
KORUS FTA(Chapter 11), a Party may deny investment benefits to investors of the other Party
that are enterprises and to their investments if: (1) the enterprise has “no substantial business
activities” in the territory or the other Party; and (2) persons of a non-Party, or of the denying
Party, own or control the enterprise.51 The threshold for “substantial business activities” is not
defined in Chapter 11 of the KORUS FTA. According to USTR, in the TPP, the United States is
seeking a “denial of benefits” provision that would prevent “the use of shell companies” from
accessing ISDS.52
Must investors exhaust their remedies in the host country’s court system first
before using ISDS?

Neither NAFTA nor the 2012 Model BIT requires exhaustion of local administrative or judicial
remedies as a prerequisite to a tribunal’s jurisdiction over an ISDS claim against a host country.53

International Investment Agreements (IIAs): Frequently Asked Questions

This may be related to U.S. concerns about inadequate judicial systems or corruption in potential
partner countries. However, at least under NAFTA, it appears that, as a matter of substantive law,
an investor seeking to establish a violation of the minimum standard of treatment obligation based
on “denial of justice” by a host country’s judiciary must have first exhausted its judicial remedies
(i.e., pursued all appeals) unless these remedies are not reasonably available.54 Tribunals have
deemed this requirement to be an element of a “denial of justice” claim under NAFTA Article
1105 (minimum standard of treatment) rather than a prerequisite to a tribunal’s exercise of
jurisdiction.55
Do investment agreements allow “forum shopping”?
“Forum shopping” generally refers to a practice in which an investor first pursues compensation
in either the host country’s local courts or before an ISDS tribunal and, if the investor is unhappy
with the outcome, then pursues compensation in the other forum. U.S. IIAs typically provide that
an investor cannot seek local remedies in the form of monetary compensation after consenting to
arbitration under the agreement. For example, under the 2012 Model BIT, an investor must, as a
condition of pursuing a claim under the ISDS provisions, agree to waive “the right to initiate or
continue before any administrative tribunal or court under the law of either Party, or other dispute
settlement procedures, any proceeding with respect to any measure alleged to constitute a breach
... ” except to the extent that the investor seeks interim injunctive relief during the pendency of
the arbitration.56 However, this does not prevent an investor from seeking local remedies in the
form of monetary compensation prior to bringing a dispute before an international investment
arbitration tribunal.
Impact on U.S. Law
What are the possible remedies?
U.S. IIAs limit the remedies that an arbitration tribunal may award. For example, in both NAFTA
and the 2012 Model BIT, the ISDS provisions state that a tribunal may award only monetary
damages and/or restitution of property.57 Furthermore, if a tribunal elects to award restitution of
property, the respondent state has the option of paying monetary damages in lieu of such
restitution.58 NAFTA and the 2012 Model BIT also provide that an arbitration panel cannot award
punitive damages.59

International Investment Agreements (IIAs): Frequently Asked Questions

Can ISDS change domestic laws?
The Constitution governs how federal statutes may be enacted, amended, or repealed.60 Therefore,
in order to amend a duly enacted statute, Congress must follow the processes established in
Article I of the Constitution.61 Because the Constitution is superior to ISDS provisions in BITs
and investment chapters in FTAs, such ISDS provisions cannot alter federal law.62 Although, to
date, the United States has yet to lose a claim brought against it under an IIA, if it were to lose a
claim in the future, the arbitration panel would not be able to amend, void the application of, or
repeal the laws of the United States.
However, a tribunal’s inability to change the laws or regulations of the United States directly does
not mean that arbitration awards cannot be substantial. For example, in Occidental Petroleum
Corp. v. Ecuador
, the tribunal ordered Ecuador to pay Occidental $1,769,625,000—over 1 billion
dollars—in damages.63 The tribunal rendered that award, which is one of the largest awards in
favor of a claimant under ISDS arbitration, after finding that Ecuador violated an investment
agreement by expropriating Occidental’s property in response to Occidental transferring some of
its economic interests under an oil production contract in contravention of Ecuador law.64
Therefore, although a tribunal lacks authority to alter a U.S. statute directly, some commentators
believe that the possibility for such large monetary damages potentially could influence
lawmakers and regulators when they consider proposed laws or regulations that may run afoul of
IIA obligations.65 However, other commentators counter that the federal government faces
potential monetary damages under its own domestic legal system for claims filed against the
government and that most would not consider this practice a threat to democratic principles.66

60 See U.S. Const. art. I; see also INS v. Chadha, 462 U.S. 919, 951 (1983) (holding the Article I of the Constitution

International Investment Agreements (IIAs): Frequently Asked Questions

How transparent is ISDS?
The level of transparency in ISDS proceedings depends on the underlying IIA giving rise to the
dispute and on the rules that the parties agree to follow during the arbitration. Generally speaking,
U.S. IIAs are regarded as providing a great level of transparency when compared to other
agreements between other countries.67 For example, under the NAFTA Free Trade Commission
interpretation of the NAFTA investment chapter, the public has access to “all documents
submitted to, or issued by, a [investor-state dispute settlement] tribunal, subject to redaction of”
confidential information, such as trade secrets or information related to national security.68
Similar transparency requirements are a U.S. trade negotiating objective, and are provided for in
the 2012 Model BIT69 and other U.S. IIAs.70
Although the transparency provisions provided for in the underlying IIA would control,
regardless of which set of arbitration rules are followed during the proceeding, it is worth noting
that the ICSID Arbitration Rules and the UNCITRAL Arbitration Rules differ with regard to
transparency requirements. Under the ICSID Arbitration Rules, the transparency provisions are
less robust than what the United States has negotiated in recent IIAs. ICSID awards are only
made publicly available if both disputing parties consent.71 Importantly, if the disputing parties do
not consent to the publication of the full award decision, ICSID Arbitration Rules still provide for
publication of “excerpts of the legal reasoning of the Tribunal.”72 Further, commentators have
noted that “oral and written submissions of the disputing parties and their experts and witnesses ...
almost always remain confidential.”73
UNCITRAL amended its Arbitration Rules in 2013 by adding Rules on Transparency in Treaty-
Based Investor-State Arbitration (Rules on Transparency).74 The Rules on Transparency will
apply to all arbitrations conducted under treaties governed by UNCITRAL Arbitration Rules that
were entered into after April 1, 2014, “unless the Parties to the treaty have agreed otherwise.”75 In
order to facilitate states to agree to follow these new transparency rules, states can sign the United
Nations Convention on Transparency in Treaty-based Investor-State Arbitration, known as the
Mauritius Convention on Transparency (Mauritius Convention).76 The Mauritius Convention
opened for signature on March 17, 2015, and provides for the Rules on Transparency to apply to

International Investment Agreements (IIAs): Frequently Asked Questions

IIAs entered into by both parties prior to April 1, 2014, by stipulating that if both parties have
signed the Mauritius Convention, they will be deemed to have agreed to apply the Rules on
Transparency to such IIAs.
Does the United States support ISDS transparency reforms?
The United States has supported ISDS transparency reforms and efforts have been made in recent
years to expand transparency, for instance through the 2004 and 2012 U.S. Model BITs. Indeed,
commentators regard U.S. IIAs as some of the most transparent agreements currently in
existence. Furthermore, the United States signed the Mauritius Convention on Transparency,
discussed above, on the first day that the Convention was opened for signature, March 17, 2015.77
In a memorandum to reporters, the USTR stated that transparency provisions in U.S. IIAs
afford respondent governments and interested members of the public the ability to monitor
the progress of ISDS proceedings in a way that they could not if the claims were filed in
many countries’ domestic court systems. Investment arbitration hearings under recent U.S.
trade and investment agreements, as well as all key documents submitted to investor-state
tribunals and tribunal decisions, are public and available on the State Department website.78
At the same time, some stakeholders remain concerned about the level of transparency in ISDS
proceedings. In the TPP, the United States is seeking “full transparency” in ISDS cases, such that
governments “must make all pleadings, briefs, transcripts, decisions, and awards in ISDS cases
publicly available, as well as open ISDS hearings to the public,” with a key objective in these
provisions being to “allow governments that are party to the agreement, as well as the public at
large, to carefully monitor pending proceedings and more effectively make decisions about
whether to intervene.”79
Can non-disputing parties contribute to the proceedings?
Similar to submissions of amicus briefs to the United States Supreme Court, ISDS arbitration
tribunals may allow interested persons, who are not parties to the dispute, to present their views to
the tribunal. The rules governing the submission of third-party statements vary depending on
whether the arbitration is governed by the ICSID Arbitration Rules, the UNCITRAL Arbitration
Rules, or some other arbitration provision. NAFTA is generally silent on amicus submissions but
provides that NAFTA parties, even when they are not involved in the particular dispute in
question, may “make submissions to a Tribunal on a question of interpretation of this
Agreement,”80 while the Model BIT provides that a non-disputing state that is a party to the treaty
“may make oral and written submissions to the tribunal regarding interpretation” of such treaty.81
The U.S. Model BIT further provides that the presiding arbitration tribunal “shall have the

authority to accept and consider amicus curiae submissions from a person or entity that is not a
disputing party.”82
The KORUS FTA provides more discretion to the tribunal regarding amicus curiae submissions.
It states that, “[a]fter consulting the disputing parties, the tribunal may allow a party or entity that
is not a disputing party to file a written amicus curiae submission with the tribunal regarding a
matter within the scope of the dispute.”83 It also provides a set of factors to be considered in
determining whether to permit an amicus curiae filing including the extent to which
• the submission would assist the tribunal in determining a factual or legal issue
related to the proceeding by bringing a perspective, particular knowledge, or
insight that differs from that of the disputing parties;
• the submission would address a matter within the scope of the dispute; and
• the third party has a significant interest in the proceeding.
Further, the KORUS FTA requires the tribunal to ensure that the submission does not disrupt the
proceeding or unduly burden or unfairly prejudice either disputing party, and that the disputing
parties are given an opportunity to present their observations on the amicus curiae submission.
The ICSID Arbitration Rules were amended in 2006 to permit submission of amicus briefs
expressly.84 ICSID arbitration tribunals have interpreted the ICSID Arbitration Rules in a manner
that requires a third-party to ask for leave to provide written statements for the tribunal’s
consideration.85 Pursuant to Rule 37, the tribunal must consult with the disputing parties prior to
permitting the submission.86 However, notably, the disputing parties do not have a “veto”
power—that is, the tribunal may allow third-party submissions over the objection of a party to the
dispute. Under the ICSID Arbitration Rules, the grant of permission to provide amicus
submissions does not permit the nonparty to attend closed hearings or get access to documents
that have not been made publicly available.87
The new UNCITRAL Rules on Transparency provisions on third-party submissions, discussed
above, are similar to the ICSID rules. The UNCITRAL Rules on Transparency provide clear
authority and procedural requirements for accepting written statements from third parties and
non-disputing states that are parties to the treaty in question.88 A third party must apply to the

85 Though Rule 37 does not explicitly state that a third-party must seek leave to submit an amicus brief, tribunals have
functioned in this manner because the tribunal, under the rule, must make a decision as to whether to allow the third-
party submission. See ICSID Arbitration Rule 37; Suez, Sociedad General de Aguas de Barcelona S.A. and Vivendi
Universal S.A. v. Argentine Republic, ICSID ARB/03/19, Order in Response to a Petition for Transparency and

who establish to the Tribunal’s satisfaction that they have the expertise, experience, and independence to be of

tribunal to make a submission, the tribunal must consult with the disputing parties, and the
tribunal must consider whether the submission would be able to assist the tribunal in making a
determination on the dispute.89 A notable difference between the UNCITRAL Rules on
Transparency and the ICSID Arbitration Rules is that the UNCITRAL Rules on Transparency
require third-party submissions to be made public.90
Do ISDS cases create precedent?
When rendering decisions in ISDS cases, investment arbitration tribunals do not establish legally
binding precedent.91 Thus, investment arbitration tribunals do not have to follow the decisions of
prior tribunals in the way that, for example, U.S. federal courts must adhere to the decisions of
the U.S. Supreme Court. However, arbitrators serving on ISDS tribunals have noted that a
tribunal departing from a holding of a prior tribunal (particularly, in a case brought under the
same IIA) may feel inclined to explain its reasoning in detail.92 As the Glamis Gold tribunal put it,
a NAFTA tribunal, “while recognizing that there is no precedential effect given to previous
decisions, should communicate its reasons for departing from major trends present in previous
decisions, if it chooses to do so.”93 Other commentators argue that there may be some value in
evaluating each case on its own merits without being tied to precedent.94
Is there an appeals process?
Currently, U.S. IIAs lack a mechanism under which a disputing party may appeal a decision of an
investment arbitration tribunal. Under ICSID Arbitration Rules,95 a committee may be established
to consider annulment of an award on five limited grounds.96 However, these committees are not
supposed to serve as appellate bodies.97

UNCITRAL Rules on Transparency are only applicable to IIAs entered into after April 1, 2014, unless the parties agree

International Investment Agreements (IIAs): Frequently Asked Questions

The United Nations Conference on Trade and Development (UNCTAD), ICSID, and other
commentators have suggested that establishing an international appellate system for ISDS arbitral
decisions could improve the overall operation of investment agreements.98 For example, an
appellate mechanism might bring some coherence to inconsistent tribunal decisions, resulting in
greater certainty for investors and host countries regarding their rights and obligations under
IIAs.99 However, to date, there does not appear to have been any concrete progress toward
establishing such a body. Some observers have noted that including an appeals process could lead
to additional delays and costs for disputing parties.100 In addition, some commentators have
questioned whether a global appellate body would be able to reconcile inconsistent decisions
based on numerous investment treaties that provide different substantive and procedural rights to
investors.101
While NAFTA does not mention an appeal process, the 2012 U.S. Model BIT provides that if “an
appellate mechanism for reviewing awards rendered by investor-State dispute settlement tribunals
is developed in the future under other institutional arrangements, the Parties shall consider
whether awards rendered under Article 34 should be subject to that appellate mechanism.”102 The

International Investment Agreements (IIAs): Frequently Asked Questions

Model BIT also provides that the parties should “strive to ensure” that any appellate process
agreed to is transparent.103
In terms of TPA, the possible creation of an appellate mechanism was first identified as a U.S.
trade policy negotiating objective on foreign investment in the 2002 TPA. The 2015 bicameral
TPA bill (H.R. 1890/S. 995) incorporates this objective as well.
What is the relationship between ISDS and state-to-state dispute settlement?
Some U.S. IIAs provide for state-to-state dispute settlement when a respondent state to an ISDS
proceeding fails to pay compensation to a prevailing investor or when state parties to the IIA
disagree about an issue of interpretation. For example, the 2012 Model BIT provides that the non-
disputing state party may bring a dispute settlement case against the respondent state if the
respondent does not comply with a final award.104 The panel hearing the dispute may determine
that the respondent state has breached its obligations under the BIT and recommend that the
respondent state abide by or comply with the award.105 State-to-state dispute settlement
proceedings may also be available when state parties to the IIA disagree over the interpretation or
application of its provisions.106
Cases and Overall Trends
Has the United States ever lost an ISDS case?
The United States has never been ordered to pay compensation to an investor in an ISDS case. At
the same time, the United States has spent a considerable amount in costs and attorneys’ fees
defending ISDS cases. According to the USTR, ISDS is “accompanied by similar legal costs to
complex litigation in [U.S. domestic] courts.”107 In addition, the United States entered into
settlement agreements with investors’ home countries to resolve issues raised by investors in the
Softwood Lumber Consolidated Proceedings (Canada)108 and the CANACAR case (Mexico).109
However, in both cases, a state-to-state dispute settlement panel had already determined that some
aspects of the U.S. measures at issue were inconsistent with U.S. WTO or NAFTA obligations.110

International Investment Agreements (IIAs): Frequently Asked Questions

How common are ISDS cases?
The right to ISDS, in some form, is a common feature of many international investment
agreements. Despite the inclusion in BITs of ISDS provisions since 1968, it was not until the mid-
1990s, following the passage of several investment agreements between advanced economies,
that the number of cases of investment disputes began increasing. Since then, the prominence of
ISDS has increased concurrent with the rapid growth of FDI in recent decades – From a
negligible amount in the 1960s global FDI flows were $1.45 trillion in 2014. Globally, in 2014,
investors initiated 42 known ISDS cases, bringing the overall known number of ISDS cases to
608 since the early 1960s.111 At the same time, in the overall context, ISDS appears to be
relatively infrequently used; for example, about 90% of all BITs in force reportedly have operated
without any claims filed.112

Who are the most frequent claimants and respondents in ISDS cases?
Investors from capital-exporting countries most frequently file ISDS claims. In terms of the total
at the end of 2014, the main users of ISDS have been investors from the United States (around
130 cases); several European countries, namely the Netherlands (over 60), the United Kingdom

(around 50), Germany (over 40), and France (nearly 40); and Canada (around 30)—collectively
representing over 80% of all ISDS claims filed.113
By contrast, developing and transition countries are the most frequent respondents in ISDS
claims. In 2014, 60% of all cases were brought against developing and transition economies, with
Argentina, Bolivia, and the Czech Republic the top three historically. In 2014, Spain was the most
frequent respondent (with five cases).114
What issues and sectors are most commonly involved in ISDS cases?
The nature of disputes brought under ISDS has evolved. For example, claims over direct
expropriation, such as those related to the nationalization of economic sectors in the 1970s and
1980s, have largely given way to disputes involving foreign investment regulation and indirect
expropriation.115 In 2014, the two types of government conduct most commonly at issue in ISDS
were cancellations or alleged violations of contracts and revocations or denial of licenses.116
Around 61% of the cases filed in 2014 related to the services sector, followed by primary
industries (28%) and manufacturing (11%).117 According to one analysis of ISDS cases during
2003-2013, the primary (oil, mining, hydrocarbon, etc.) and electricity generation and distribution
sectors were the most frequently involved in cases.118 Another analysis characterizes the
economic sectors most frequently involved in ISDS cases generally as ones with “significant
government involvement or those governments view as critical for the national economy.”119
Who typically wins ISDS cases?
Cumulatively, in 2014, the global number of concluded ISDS cases reached 356, with 37%
decided in favor of the host country; 25% in favor of the investor, and 28% settled.120 Information
regarding the amounts claimed by investors is limited, though efforts to enhance transparency
exist: for example, in the 2012 U.S. Model BIT and the new UNCITRAL rules. Internationally,
from available information on cases, the amounts sought in claims by investors historically have
varied from about $8 million to $2.5 billion.121 In cases where investors win, the damages
awarded are often lower (see text box).122 One dispute that has been characterized as being a
record high is the aggregate amount of $1.77 billion sought by three claimants who constituted

the majority shareholders of the former Yukos Oil Company in an arbitration proceeding against
Russia, and the subsequent award issued against Russia of $50 billion.123
How Do ISDS Award Amounts Vary by Countries’ Development Status?
Of both policy and academic interest has been the extent to which amounts awarded have varied between countries,
based on development status, particularly with respect to the debate over whether ISDS causes a regulatory chilling
effect. One recent analysis, which used a dataset of 159 final investment treaty arbitration awards from before January
2012, found that the average amount awarded was $2.95 million.124 The study did not find a statistically significant
difference in the average award amounts for arbitration cases based on whether countries were OECD or non-
OECD members. In contrast, it found an overall statistical y significant pattern for average award amounts based on
countries’ World Bank classification by income (high, upper-middle, lower-middle, and low income)—specifically that
average awards for investors against high-income countries ($626,000) were lower than average awards for investors
against upper-middle income countries (about $4 million). It explored the outcomes in other ways as well. The study
noted several limitations to its findings, including possible statistical modeling limitations, variables omitted (e.g., the
possible impact of democracy levels on outcomes), and assumptions. Such analysis has been used by some ISDS
supporters to give weight to the argument that ISDS is not biased against developing countries. On the other hand,
amounts claimed and awarded can nevertheless “exert significant pressure on public finances and create potential
disincentives for public-interest regulation.”125 At the same time, exposure to ISDS might also encourage more non-
discriminatory treatment. . Additionally, some scholars have observed that while empirical research on ISDS may play
a role in informing the investment policy debate, empirical research has limitations and “cannot… prove or disprove
systemic bias in arbitral decision-making.”126
Under which agreements have ISDS cases most commonly been brought
against the United States?

According to the USTR, under the 50 agreements the United States has concluded which include
ISDS, the United States has faced “17 ISDS cases, 13 of which were brought to conclusion.”127
Nearly all ISDS cases brought by investors against the United States have been brought under
NAFTA. Additionally, one case has been filed under each of the CAFTA-DR, the U.S.-Chile
FTA, the U.S.-Peru FTA, and the U.S. Uruguay BIT by foreign investors.128 None of these cases
was decided against the United States.
What are examples of recent ISDS cases?
The Appendix contains a summary of the facts and outcomes of recent ISDS cases that may be of
interest to Congress. Not all of these cases involve claims under U.S. IIAs. Some have played a
role in current U.S. investment negotiations and the U.S. trade policy debate over immigration.

International Investment Agreements (IIAs): Frequently Asked Questions

For example, in recent years, two cases concerning the pharmaceutical industry and intellectual
property rights have been prominent: one filed by a subsidiary of Philip Morris against Australia
concerning its plain packaging law for tobacco129 and the other filed by Eli Lilly against Canada
regarding its so-called “promise doctrine” concerning patent utility.130 For example, businesses
claim an interest in seeking compensation for what they consider to be deprivation of their
property (IPR) through a fair hearing in a neutral body.131 Others argue that these cases infringe
on a state’s right to regulate in the public welfare, and that the “mere threat” of litigation can have
a “chilling effect on policy.”132 Some observers argue that these cases are not “representative” of
ISDS, and express caution as to drawing any conclusions from either case, given that in neither
case has the tribunal yet issued an award on jurisdiction or on the merits in the dispute.133


129 On December 1, 2011, the Tobacco Plain Packaging Act 2011 became law in Australia. The law requires “plain
packaging” and new and expanded health warnings on tobacco products, and prohibits the use of logos, brand imagery,
and promotional text on tobacco products. See Australian Government, The Department of Health, “Plain Packaging of
Tobacco Products,” updated March 2, 2015, http://www.health.gov.au/tobaccopp.
130 According to the Canadian government, the so-called “promise doctrine” “consists of distinct tests for patent
validity under Canadian law.” Further, “[i]n Canadian patent law, fulfilment of the three core criteria of patentability—
novelty, non-obviousness, and utility—is judged no later than as at the time of filing of the patent application.” A
Canadian court reviewing a claim that a patent is invalid on utility grounds “will first seek to determine whether the
applicant itself asserted (“or promised”) a particular level of utility for its invention in its patent specification.”
According to the USTR 2014 Special 301 Report, the United States has “serious concerns about the lack of clarity and
the impact of the heightened utility requirements for patents that Canadian courts have applied recently.” USTR states
that, “[u]nder this amorphous and evolving standard, courts can invalidate a patent on utility grounds by construing the
“promise of a patent” years after the patent has been granted, leading to uncertainty for patent holders and applicants
and undermining incentives for investment in the pharmaceutical sector. In applying this standard, courts have
invalidated a number of patents held by U.S. pharmaceutical companies, finding now that those products lack utility
(i.e., not capable of industrial application), even though such products have been in the market and benefiting patients
for years.”

In its defense, Canada argued that

patents did not amount to a “denial

had provided Lilly with sufficient due
process. Nor, in Canada’s view,
could the court’s violation of the
alleged “expectations” the investor
had with regard to Canada’s patent
law breach NAFTA the minimum
standard of treatment.
With respect to Lilly’s expropriation
claim, Canada argued that a court’s
invalidation of an initial patent grant
does not amount to an
expropriation. Instead, it constitutes
a determination that the investor has
no property rights in the alleged
invention. Canada also argued that
the court decisions were consistent
with NAFTA Chapter 17.
