The European Union’s Reform Process: The Lisbon Treaty

Summary
The Lisbon Treaty, the latest institutional reform treaty of the European Union (EU), went into
effect on December 1, 2009. The document was signed by the heads of state or government of the
27 EU member countries in December 2007. The process of completing ratification by each
individual member country lasted nearly two years, concluding with ratification by the Czech
Republic on November 3, 2009. The Lisbon Treaty reforms the EU’s governing institutions and
decision-making process to enable the EU to operate more effectively. The treaty grew out of the
proposed “constitutional treaty” that foundered after French and Dutch voters rejected it in
referendums in 2005.
The Lisbon Treaty seeks to give the EU a stronger and more coherent voice with the creation of a
new position, President of the European Council. The first holder of this office will be former
Belgian Prime Minister Herman Van Rompuy. He will chair the activities of the 27 EU heads of
state or government, working to facilitate consensus, coordinate the activities of the Council, and
ensure policy continuity. Additionally, the Lisbon Treaty creates the new position of High
Representative of the Union for Foreign Affairs and Security Policy, a de facto EU foreign
minister who may increase the weight and visibility of the EU on the world stage. The “foreign
minister” will be supported by a new EU diplomatic service. Catherine Ashton (from the United
Kingdom), formerly European Commissioner for Trade, was chosen for this position.
The treaty also makes changes to the EU’s internal decision-making mechanisms. These changes
have been designed to streamline the process and make it less susceptible to gridlock or blockage.
Additional reforms attempt to address concerns about democratic accountability and transparency
in EU policy-making by granting a greater role to the directly elected European Parliament,
national parliaments, and citizens’ initiatives.
Experts assert that the Lisbon Treaty could have positive implications for U.S.-EU relations.
Some observers believe that it could allow the EU to move past its recent preoccupation with
distracting internal questions and take on a more active and effective role as a U.S. partner in
tackling global challenges. There are indications that adoption of the Lisbon Treaty could make
the EU more amenable to future enlargement, including to the Balkans and perhaps Turkey,
which the United States supports. On the other hand, some observers doubt how much of an
impact the Lisbon Treaty will have, and some skeptics maintain that a stronger EU poses a
potentially detrimental rival to NATO and the United States.
This report provides information on the Lisbon Treaty and possible U.S.-EU implications that
may be of interest to the 111th Congress. Also see CRS Report RS21372, The European Union:

and the Treaty of Amsterdam (1999) refined arrangements for a Union at 15. The Treaty of Nice
(2003) further amended the workings of the EU to prepare for eastward enlargement.3 The Nice
Treaty was also supposed to streamline EU decision-making to allow an enlarged Union to
function more effectively. However, critics charged that Nice set up an even more complex and
less efficient decision-making process that was too prone to confusion and gridlock. Some also
lamented that Nice did not provide sufficient mechanisms and arrangements that would allow the
EU to assert a stronger global role. In addition, Nice did little to stem charges that EU institutions
and decision-making lack transparency and democratic accountability and are unintelligible to the
average European citizen.
As the scope of EU policy continues to grow, future enlargement beyond 27 members is likely:
Iceland, Turkey, and the countries of the Western Balkans are in line for admission. In this
context, as well as in the context of perceived institutional shortcomings, many leaders and
analysts advocated the adoption of a new EU treaty that enacts what they have considered to be
necessary internal reforms. The Lisbon Treaty is the result of these efforts.
The Constitutional Treaty
The Lisbon Treaty grew out of the so-called constitutional treaty, an earlier failed attempt to
merge the EU’s existing treaties into a single document while enacting institutional reforms.
Already in December 2001—before ratification of the Treaty of Nice and the EU’s eastward
enlargement—EU leaders announced they would convene a Convention on the Future of Europe
to examine the EU’s institutional arrangements and make proposals that would increase
democratic legitimacy and encourage the development of the EU as a stronger global actor.
The Convention began work in March 2002 under the leadership of former French President
Valéry Giscard d’Estaing and finalized a 240-page “Draft Treaty establishing a Constitution for
Europe” in July 2003.4 After a period of discussion and negotiation among the member state
governments, EU leaders signed the treaty in October 2004 and set November 2006 as the target
date for its adoption.
However, in order to come into effect the treaty had to be ratified individually by all 27 member
states through either parliamentary approval or public referendums. In May 2005, French voters
rejected the document in a national referendum, and in June 2005 Dutch voters followed suit.
Although a number of EU members had already approved the treaty by this point, these setbacks
effectively ended its prospects. In both France and the Netherlands, some arguments against the
constitutional treaty reflected concerns that it would entrench liberal economic ideas that could
undermine social protections. In addition, many French and Dutch voters viewed a “no” vote as a
way to express dissatisfaction with their unpopular national governments, EU bureaucracy, and
Turkey’s prospective EU membership.

The European Union’s Reform Process: The Lisbon Treaty

The Lisbon Treaty
In January 2007, as Germany took over the six-month EU presidency, Europe remained in what
some analysts called a “period of reflection”—a condition of stasis born in the uncertainty that
followed the rejection of the constitutional treaty. German Chancellor Angela Merkel made
reviving the stalled reform process one of her key priorities, seeking a new treaty deal that would
institute crucial reforms. Analysts say that Merkel received a key assist with the May 2007
election of Nicolas Sarkozy as President of France: Sarkozy shared Merkel’s goal of reviving the
constitutional treaty in some form, at least in part to restore France’s role as a leader in Europe
following its 2005 “no” vote.
Germany and others that had ratified the constitutional treaty wanted to preserve as much of the
original document as possible. However, some changes were considered necessary in order to
address concerns raised by French and Dutch voters, as well as to satisfy countries such as the
UK, which sought to protect its national sovereignty in some areas, and Poland, which wanted
more voting weight in the Council of Ministers.
After contentious negotiations at the June 2007 EU Summit, EU leaders announced the outlines
of a new “reform treaty” that would amend, rather than replace, the existing EU treaties. EU
leaders also dropped the term “constitution,” given that it had become negatively associated in
some countries with creating an EU “superstate.” After working out the text at a July 2007
Intergovernmental Conference, EU leaders met in Lisbon and signed the new treaty in December
2007.5 Analysts assessed that over 90% of the substance of the constitutional treaty had been
preserved in the Lisbon Treaty.
As an amendment to existing treaties, EU leaders sought to present the new document as one that
would be ratified by parliaments, thereby avoiding the risks of public referendums. However,
Ireland is required by its national law to hold a public vote on any major change to the EU rules.
EU officials initially hoped that the Lisbon Treaty would be ratified by all 27 member states and
enter into force before the June 2009 European Parliament elections, but rejection of the treaty in
Ireland’s June 2008 referendum threw the timetable for adoption into disarray. Influenced by an
active “no” campaign, Irish voters feared the treaty would hurt their economy, strip their
sovereignty on tax policy and sensitive issues such as abortion, and impinge on their stance of
neutrality in security and defense issues. Irish leaders agreed to hold a second referendum, and
following the negotiation of EU concessions and “guarantees” in areas of concern to Ireland, as
well as a stronger “yes” campaign that sought to convince the public of the treaty’s benefits, Irish
voters decisively approved the treaty on October 2, 2009. The Czech Republic completed the
final national ratification on November 3, allowing the treaty to come into effect on December 1.
Key Reforms
Major changes under the Lisbon Treaty aim to achieve three broad goals:
(1) A stronger and more coherent EU voice. The Lisbon Treaty creates the new position of
President of the European Council to chair the meetings of the 27 EU heads of state or

government. The President of the European Council is elected by the member states for a term of
two and one-half years, renewable once.
Some had envisioned this position as a driver of EU policy, a heavyweight presidential figure
who would play a highly visible international role. In choosing former Belgian Prime Minister
Herman Van Rompuy, however, EU leaders have initially defined this position as more of a
manager who will coordinate the activities of the Council, help ensure policy continuity, and
work to facilitate consensus. Van Rompuy’s experience in negotiating and holding together
coalitions in the often fractious arena of Belgian national politics was considered by many as an
asset that fit well with the job description. According to some analysts, this choice confirms that
even as its members pursue a stronger and more integrated EU, considerations of national
influence and prestige remain key: leaders from both large and small countries sought to avoid
establishing a powerful President who might overshadow or marginalize their own roles.
The Lisbon Treaty also creates another important new position to boost the EU’s international
visibility: High Representative of the Union for Foreign Affairs and Security Policy. The position
was originally called the EU “foreign minister” in the constitutional treaty, but this term was
dropped due to British objections. Nevertheless, this individual is to be the EU’s chief diplomat,
exercising the former responsibilities of the Council of Ministers’ High Representative for the
Common Foreign and Security Policy (formerly Javier Solana) and the Commissioner for
External Relations (formerly Benita Ferrero-Waldner), who oversaw the EU’s foreign aid and
development policies. The new High Representative will therefore be an agent of the Council of
Ministers (representing the member states) and hold the title of a Vice-President of the European
Commission, an institutional adjustment intended to impart greater coherence by marrying the
EU’s political and economic clout in one powerful new office. The High Representative is to have
extensive staff support with the creation of a European External Action Service, in effect a new
EU diplomatic corps.
The desired nature of the “foreign minister” produced a debate similar to that over the
President—whether the position should act as a strong, independent-minded leader who both
drives and oversees EU foreign policy, or as more of a facilitator who advances the members’
consensus. At this time, the answer remains inconclusive. After some EU officials unsuccessfully
attempted to promote UK Foreign Secretary David Miliband for the position, EU leaders
ultimately agreed on Baroness Catherine Ashton (also of the United Kingdom), formerly
European Commissioner for Trade. Some observers were surprised at this choice, given Ashton’s
relative lack of foreign policy experience. Others note, however, that she has a considerable
opportunity to define the nature of the position through her actions and initiatives. Some analysts
assert that with its extensive political and developmental aid resources and potential to wield
considerable influence, this strengthened High Representative post could be the more significant
of the positions created by the Lisbon Treaty.
The Lisbon Treaty also promotes steps toward building a stronger common EU defense policy. As
proposed in the former constitutional treaty, the Lisbon Treaty asserts that the EU shall seek “the
progressive framing of a common Union defense policy,” which “will lead to a common
defense.” It will establish a “mutual assistance clause” permitting a member state that is the
victim of armed aggression to ask for military assistance from the other members. Member states
may also engage in “structured cooperation,” which would allow a smaller group of members to
cooperate more closely on military issues.

(2) More streamlined decision-making. After a contentious debate with Poland, EU leaders agreed
on a simplified formula (ultimately similar to that proposed in the constitutional treaty) for the
Council of Ministers’ Qualified Majority Voting (QMV) system. Decisions made by QMV would
pass if supported by 55% of member states, representing 65% of the EU’s population. As a
concession to Poland, this new “double majority” system is to be introduced in 2014 (instead of
2009-2010), gradually phased in over three years, and not fully implemented until 2017.
The use of QMV is also expanded to policy areas previously subject to unanimity, especially in
matters related to police and judicial cooperation (the UK, however, has been granted an opt-out
in this area). Unanimity will continue to be required (any member state may veto a common
policy) in sensitive areas such as taxation and most aspects of foreign and defense policy.
The Lisbon Treaty had initially planned to slim down the size of the European Commission
starting in 2014. To help decrease gridlock, EU leaders had proposed reducing the number of
Commissioners from one per member state to correspond to two-thirds of the number of member
states. However, concessions related to Ireland’s attempt to ratify the treaty shelved this idea, and
the Commission will remain at one Commissioner per member state.
(3) Increased transparency and democratic accountability. In many policy areas, the directly
elected European Parliament holds the right of “co-decision” with the Council of Ministers: both
institutions must approve a piece of legislation for it to become law. The Lisbon Treaty extends
the European Parliament’s “co-decision” powers to include many additional policy areas,
including agriculture, trade, and “home affairs” issues.
The treaty also gives national parliaments a greater role in EU policy-making and more authority
to challenge draft EU legislation. The treaty introduces the concept of citizens’ initiatives,
whereby European citizens may petition the European Commission with legislative suggestions.
Additionally, the Lisbon Treaty makes the Charter of Fundamental Rights—a declaration of
citizens’ basic political, economic, and social rights—legally binding for all EU institutions and
member states. Poland, the Czech Republic, and the United Kingdom negotiated “opt-outs” from
applying the Charter.
Implications for the United States
Many experts assert that the Lisbon Treaty could have positive implications for U.S.-EU
relations. After the appointment of Van Rompuy and Ashton, a White House statement asserted
that “the United States has no stronger partner than Europe in advancing security and prosperity
around the world. These two new positions, and related changes to take effect on December 1 as a
result of the implementation of the Lisbon Treaty, will strengthen the EU and enable it to be an
even stronger partner to the United States.”6
If the EU is able to increasingly “speak with one voice” on global issues—a stronger, more
consistent, and more coherent voice—proponents of close U.S.-EU ties argue that the EU could

take a more active and assertive international role and be a more credible and effective partner for
the United States in tackling common challenges. The Lisbon Treaty is not a revolutionary
overhaul of the way the EU works, but the changes it makes may allow the EU to achieve
consensus more easily, make policy decisions more quickly, and project its weight and influence
more effectively. Supporters of the Lisbon Treaty also note that efforts to encourage a common
EU defense policy and the proposal for “structured cooperation” seek to improve European
defense capabilities. A more militarily capable Europe, they argue, could shoulder a greater
degree of the security burden with the United States. In addition, some analysts assert that the
Lisbon Treaty may help lead to the formation of stronger EU-wide policies in policing and
judicial issues, which could further enhance transatlantic cooperation in matters of homeland
security.
Analysts assert that the treaty could remove some obstacles to further EU enlargement to the
Balkans and perhaps eventually Turkey, which the United States supports. European leaders had
previously asserted that the streamlining reforms of the treaty could make the political
atmosphere more amenable to additional enlargement, and some had called for a freeze on
enlargement until the treaty was passed.
Critics, on the other hand, contend that the Lisbon Treaty will do little to simplify the EU, and
assert that many difficult issues that are often the source of gridlock—such as foreign policy and
taxation—will remain subject to national vetoes. Some question whether the new positions
created by the treaty will resonate in the United States. They wonder, for example, how much of a
difference U.S. officials might discern between the new “foreign minister” and the previous
position that was held by Javier Solana. Some skeptics of the EU in the United States contend that
a larger and potentially more united EU may seek to rival the United States and could sometimes
be an opponent, rather than a partner, in a variety of policy areas. They maintain that a more
unified EU would likely lessen Washington’s leverage on individual members and could
complicate U.S. efforts to rally support for its initiatives in institutions such as the United Nations
or NATO. These skeptics remain concerned that parts of the Lisbon Treaty promoting greater EU
defense coordination could lead to the eventual development of EU military structures that would
duplicate those of NATO and weaken the transatlantic link.
In any case, most agree that one considerable benefit of the adoption of the Lisbon Treaty is that
the EU can now move past this decade’s preoccupation with process and internal institutional
questions to focus more time and energy on “doing things.”
U.S.-EU trade relations could potentially be affected by the new treaty. The European
Commission maintains its role in formulating the EU’s external trade policy and negotiating trade
agreements, and the Council of Ministers must still approve or reject trade agreements negotiated
by the Commission. However, it is significant that the European Parliament gains “co-decision”
powers with the Council in trade matters, and now acts as a “co-legislator” with an enhanced and
more formal role in these areas.
This change reflects the fact that the overall institutional power and responsibilities of the
European Parliament have been increased by the Lisbon Treaty. The European Parliament has
long sought to strengthen interparliamentary ties with the U.S. Congress, and its enhanced role
may further prompt those who argue for deepening the relationship between the two institutions.
The Transatlantic Legislators’ Dialogue (TLD) is the formal mechanism for engagement and
exchange between the U.S. House of Representatives and the European Parliament.
