World Trade Organization (WTO) Decisions and Their Effect in U.S. Law

Summary
Congress has comprehensively dealt with the legal effect of World Trade Organization (WTO)
agreements and dispute settlement results in the United States in the Uruguay Round Agreements
Act (URAA), P.L. 103-465. The act provides that domestic law prevails over conflicting
provisions of WTO agreements and prohibits private remedies based on alleged violations of
these agreements. As a result, provisions of WTO agreements and WTO panel and Appellate
Body reports adopted by the WTO Members that are in conflict with federal law do not have
domestic legal effect unless and until Congress or the executive branch, as the case may be, takes
action to modify or remove the conflicting statute, regulation, or regulatory action. Violative state
laws may be withdrawn by the state or, in rare circumstances, invalidated through legal action by
the federal government.
The URAA also contains requirements for agencies to follow where a change in a regulation or
the issuance of a new agency determination in a trade remedy proceeding is needed to comply
with a WTO decision and existing law may be sufficient to carry out the action.
While the URAA prohibits private rights of action based on Uruguay Round agreements,
plaintiffs, in cases brought under other statutes, have argued that the agency actions they are
challenging in court are inconsistent with a WTO agreement or a WTO decision and should
conform with U.S. WTO obligations. Although courts have deemed WTO decisions to be
persuasive, they have also held that they are not binding on the United States, U.S. agencies, or
the judiciary, leaving the issue of whether and how the United States complies in a particular
WTO proceeding to the executive branch.
Legislation introduced in recent Congresses generally reflected congressional concerns that the
WTO Appellate Body had interpreted WTO agreements in an overly broad manner to the
detriment of the United States and that the executive branch had in some cases too readily used
existing statutory authorities to comply with these decisions, particularly where U.S. trade
remedies were involved. Legislation particularly focused on WTO decisions finding the U.S. use
of “zeroing” in antidumping proceedings to be in violation of the WTO Antidumping Agreement
and an administrative modification instituted by the Department of Commerce in original
antidumping investigations in response to one of the earliest of these decisions. Under the
practice, the department calculates dumping margins by taking into account only sales below fair
market value—generally the price in the exporting country—and assigns a zero value to sales at
or above this price. While it is argued that zeroing improperly creates or inflates dumping
margins, U.S. courts have consistently upheld the department’s use of the practice as valid under
U.S. antidumping law.

World Trade Organization (WTO) Decisions and Their Effect in U.S. Law

Uruguay Round Agreements Act (URAA)
The Uruguay Round of Multilateral Trade Negotiations, initiated in 1986 under the auspices of
the General Agreement on Tariffs and Trade (GATT), concluded in 1994 with the signing of the
Marrakesh Agreement Establishing the World Trade Organization (WTO Agreement). The WTO
Agreement, which entered into force January 1, 1995, requires any country that wishes to be a
WTO Member to accept all of the multilateral trade agreements negotiated during the Round. The
Uruguay Round package of agreements not only carries forward long-standing GATT obligations,
such as according goods of other parties nondiscriminatory treatment, not placing tariffs on goods
that exceed negotiated or “bound” rates, generally refraining from imposing quantitative
restrictions such as quotas and embargoes on imports and exports, and avoiding injurious
subsidies, but also expands on these obligations in new agreements such as the Agreement on
Agriculture, the Agreement on the Application of Sanitary and Phytosanitary Measures, the
Agreement on Antidumping, the Agreement on Subsidies and Countervailing Measures, the
General Agreement on Trade in Services (GATS), and the Agreement on Trade-Related Aspects
of Intellectual Property Rights (TRIPS).
The Uruguay Round package also includes the Understanding on Rules and Procedures
Governing the Settlement of Disputes (Dispute Settlement Understanding or DSU), which applies
to disputes between WTO Members arising under virtually all WTO agreements. Dispute
settlement is administered by the WTO Dispute Settlement Body (DSB), an entity consisting of
all WTO Members. The dispute settlement process consists of consultations, panels and possible
appeals, adoption by the DSB of the resulting panel and appellate reports, and, if the defending
Member is found to have violated a WTO obligation, implementation of the WTO decision by
that Member, generally within an established “reasonable period of time.” If the Member has not
complied by this date, the prevailing Member may seek compensation from the non-complying
Member or obtain authorization from the DSB to impose retaliatory measures, such as increased
tariffs on selected products exported from the non-complying Member’s territory.
Congress approved and implemented the WTO Agreement and the other agreements negotiated in
the Uruguay Round in the Uruguay Round Agreement Act (URAA), P.L. 103-465, 19 U.S.C. §§
3501 et seq. In enacting the URAA, Congress comprehensively dealt with the legal effect in the
United States of both the Uruguay Round agreements and WTO decisions adverse to the United
States resulting from dispute settlement proceedings under the new DSU. The URAA addresses
the relationship of WTO agreements to federal and state law and prohibits private remedies based
on alleged violations of WTO agreements. It also requires the United States Trade Representative
(USTR) to keep Congress informed of disputes challenging U.S. laws once a dispute panel is
established, any U.S. appeal is filed, and a panel or Appellate Body report is circulated to WTO
Members. In addition, the URAA places requirements on agencies taking domestic regulatory
action to implement WTO decisions, including provisions specific to successfully challenged
agency determinations in U.S. trade remedy proceedings.

World Trade Organization (WTO) Decisions and Their Effect in U.S. Law

Domestic Legal Effect of WTO Decisions Under
the URAA

As is the case with previous trade agreements, including the North American Free Trade
Agreement (NAFTA) and the GATT Tokyo Round agreements, Congress considers the Uruguay
Round agreements to be non-self-executing; that is, their legal effect in the United States is based
on their implementing legislation (i.e., the Uruguay Round Agreements Act (URAA)).1 To this
end, the URAA approves the agreements and contains provisions “necessary or appropriate” to
implement them, including provisions setting out new and revised authorities as well as any
needed repeals. In addition, section 102 of the URAA and its legislative history establish that
domestic law supersedes any inconsistent provisions of WTO agreements approved and
implemented in the URAA and that WTO decisions involving U.S. laws or regulatory actions that
are successfully challenged in the WTO do not have direct or automatic legal effect in the United
States. Instead, specific congressional or administrative action, as the case may be, is required to
implement these WTO decisions.
Federal Law
Section 102(a)(1) of the URAA states that “[n]o provision of any of the Uruguay Round
Agreements, nor the application of any such provision to any person or circumstance, that is
inconsistent with any law of the United States shall have effect.”2 Section 102(a)(2) further
provides that nothing in the statute “shall be construed ... to amend or modify any law of the
United States ... or ... to limit any authority conferred under any law of the United States ... unless
specifically provided for in this act.”3
The Statement of Administrative Action (SAA) that accompanied the WTO agreements when
they were submitted to Congress by the President in 1994 explains that “[i]f there is a conflict
between U.S. law and any of the Uruguay Round agreements, section 102(a) of the implementing
bill makes clear that U.S. law will take precedence.”4 Moreover, § 102 is intended to clarify that
all changes to U.S. law “known to be necessary or appropriate” to implement the WTO

Uruguay Round SAA, which was expressly approved in § 101(a)(2) of the URAA, 19 U.S.C. § 3511(a)(2), is to be
regarded as “an authoritative expression by the United States concerning the interpretation and application of the
Uruguay Round Agreements and ... [the URAA] in any judicial proceeding in which a question arises concerning such
interpretation or application.” URAA, § 102(d), 19 U.S.C. § 3512(d). The submission of an SAA—that is, “a statement
of any administrative action proposed to implement” the trade agreements being sent to Congress—is a requirement of
the statutory authority under which the Uruguay Round agreements were approved and implemented. See Omnibus
Trade and Competitiveness Act (OTCA), as amended, P.L. 100-418, § 1103 (a)(1)(B), 19 U.S.C. § 2903(a)(1)(B).

agreements are incorporated in the URAA and that statutory changes needed “to remedy an
unforeseen conflict” between U.S. law and WTO agreements “can be enacted in subsequent
legislation.”5 This approach, which Congress has taken in addressing potential conflicts between
domestic law and prior GATT and free trade agreements, is considered to be “consistent with the
Congressional view that necessary changes in Federal statutes should be specifically enacted, not
preempted by international agreements.”6
The implementation of WTO dispute settlement results is to be similarly treated. URAA
legislative history states that “[s]ince the Uruguay Round agreements as approved by the
Congress, or any subsequent amendments to those agreements, are non-self-executing, any
dispute settlement findings that a U.S. statute is inconsistent with an agreement also cannot be
implemented except by legislation approved by the Congress unless consistent implementation is
permissible under the terms of the statute.”7 In the event a statute permits implementation
consistent with the WTO decision, Congress has specified procedures for agencies to follow in
taking administrative action to comply. These requirements are discussed below.
State Law
Where state law is at issue in a WTO dispute, section 102(b) of the URAA provides for federal-
state cooperation in the WTO proceeding, requires the USTR to work with the state to “develop a
mutually agreeable response” to an adverse WTO ruling, and allows the United States alone to
bring domestic legal challenges to the state law. The act’s general preclusion of private remedies
(discussed below) further centralizes the response to adverse WTO decisions involving state law
in the federal government.8
Section 102(b) states that “[n]o State law, or the application of a such a State law, may be
declared invalid as to any person or circumstance on the ground that the provision or its
application is inconsistent with any of the Uruguay Round Agreements, except in an action
brought by the United States for the purposes of declaring such law or application invalid.”9
According to legislative history, the provision “makes clear that the Uruguay Round agreements
do not automatically preempt State laws that do not conform to their provisions, even if a WTO
dispute settlement panel or the Appellate Body were to determine that a particular State measure
was inconsistent with one or more of the Uruguay Round agreements.”10 The statute also contains
restrictions on any such U.S. legal action, including that the report of the WTO dispute settlement

The SAA states: “Reports issued by panels or the Appellate Body under the DSU have no binding effect under the law
of the United States and do not represent an expression of U.S. foreign or trade policy. They are no different in this
respect than those issued by GATT panels since 1947. If a report recommends that the United States change federal law
to bring it into conformity with a Uruguay Round agreement, it is for the Congress to decide whether any such change
will be made.”

panel or the Appellate Body may not be considered binding on the court or otherwise accorded
deference.11 Any such suit by the United States is expected to be a rarity.12
Preclusion of Private Remedies
Private remedies are prohibited under § 102(c)(1) of the URAA, which provides that “[n]o person
other than the United States ... shall have a cause of action or defense under any of the Uruguay
Round Agreements or by virtue of congressional approval of such an agreement” or “may
challenge, in any action brought under any provision of law, any action or inaction by any
department, agency, or other instrumentality of the United States, any State, or any political
subdivision of a State, on the ground that such action or inaction is inconsistent with such
agreement.”13 Congress has additionally stated in the statute that it intends, through the
prohibition on private remedies:
to occupy the field with respect to any cause of action or defense under or in connection with
any of the Uruguay Round Agreements, including by precluding any person other than the
United States from bringing any action against any State or political subdivision thereof or
raising any defense to the application of State law under or in connection with any of the
Uruguay Round Agreements—(A) on the basis of a judgment obtained by the United States
in an action brought under any such agreement; or (B) on any other basis.14
The House Ways and Means Committee report on the URAA explains that because of this
provision a private party, for example, “cannot bring an action to require, preclude, or modify
government exercise of discretionary or general ‘public interest’ authorities under the other
provisions of law.”15 The joint Senate committee report on the act adds that this provision would
preclude any action by a private party against a state “under or in connection with any Uruguay
Round agreement, including … [one] based on Congress’ authority under the Commerce Clause
of the U.S. Constitution.”16 Overall, the House Ways and Means Committee report states, the
prohibitions on private rights of action “are based on the premise that it is the responsibility of the
Federal Government, and not private citizens, to ensure that Federal or State laws are consistent
with U.S. obligations under international agreements such as the Uruguay Round agreements.”17
The SAA notes, however, that § 102(c) “does not preclude any agency of government from
considering, or entertaining argument on, whether its action or proposed action is consistent with

12 Uruguay Round SAA, supra note 4, at 674; H.Rept. 103-826(I), at 26; S.Rept. 103-412, at 15. The SAA states, inter
alia
, that the Attorney General “will be particularly careful in considering recourse to this authority where the state
measure involved is aimed at the protection of human, animal, or plant health or of the environment or the state
measure is a state tax of a type that has been held to be consistent with the requirements of the U.S. Constitution. In
such a case, the Attorney General would entertain use of this statutory authority only if consultations between the
President and the Governor of the State concerned failed to yield an appropriate alternative.” Uruguay Round SAA,

the Uruguay Round agreements, although any change in agency action would have to be
authorized by domestic law.”18
Domestic Administrative Implementation of WTO
Decisions Under the URAA

The Uruguay Round Agreements Act sets out procedures that agencies must follow in
implementing WTO decisions that are adverse to the United States where existing statutory
authorities may be sufficient to do so. Section 123 of the URAA addresses regulatory
modifications in general, while § 129 addresses the issuing of new determinations in certain
domestic trade remedy proceedings. In some cases, implementation of a WTO decision may
involve the exercise of authorities under both provisions.
Domestic Regulations and Administrative Practices
(URAA, § 123(g))

Section 123(g) of the URAA provides that in any case in which a report of a WTO panel or the
Appellate Body finds that an administrative regulation or practice is inconsistent with a WTO
agreement, the regulation or practice may not be “amended, rescinded or otherwise modified in
implementation of such report unless and until” the USTR and relevant agencies consult with
Congress, seek private sector advice, and publish the proposed change in the Federal Register
with a request for public comment, and the final rule or other modification is published in the
Federal Register.19 Section 123(g) mandates a 60-day consultation period with Congress and
provides that the Senate Finance and House Ways and Means Committees may vote to indicate
their agreement or disagreement with the proposed action during this period.20 Section 123(g)
does not apply to regulations or practices of the U.S. International Trade Commission.
Determinations in Trade Remedy Proceedings (URAA, § 129)
Section 129 of the URAA sets forth authorities and procedures to be used by the United States
Trade Representative, the U.S. International Trade Commission (USITC), and the Department of
Commerce (DOC) in implementing adverse WTO panel and Appellate Body (AB) reports
involving agency determinations in U.S. safeguards, antidumping, and countervailing duty
proceedings.21 The conduct of these proceedings is subject to rights and obligations in,

18 Uruguay Round SAA, supra note 4, at 676.
19 URAA, § 123(g), 19 U.S.C. § 3533(g).
20 The provision first came into play in 1996 when the United States took regulatory action to comply with the adverse
WTO decision in United States—Standards for Reformulated and Conventional Gasoline, WT/DS2, WT/DS4. See
World Trade Organization (WTO) Decision on Gasoline Rule (Reformulated and Conventional Gasoline), 61 Fed. Reg.
33703 (June 28, 1996). The U.S. Court of Appeals for the D.C. Circuit upheld the final issued by EPA to resolve the
dispute, finding, inter alia, that the agency was not statutorily precluded from considering factors other than air quality
in issuing rules under the antidumping provision of the Clean Air Act and could thus consider the effect of the proposed
rule on U.S. treaty obligations. George E. Warren Corp. v. U.S. Environmental Protection Agency, 159 F.3d 616

respectively, the WTO Agreement on Safeguards, the Agreement on Antidumping, and the
Agreement on Subsidies and Countervailing Measures.
In safeguards proceedings, as authorized in Title II of the Trade Act of 1974, 19 U.S.C. §§ 2251 et
seq.
, the USITC, either on the basis of a domestic industry petition, executive or legislative
branch request, or its own motion, conducts an investigation to determine whether or not
increased imports of a particular product are a substantial cause of serious injury (or threat of
serious injury) to a domestic industry producing a product that is like, or directly competitive
with, the imported good. If injury is found, the President may temporarily restrict imports or take
other measures to remedy the harm to U.S. firms.
Antidumping and countervailing duty investigations, which are authorized in Title VII of the
Tariff Act of 1930, 19 U.S.C. §§ 1671 et seq., and may be initiated by petition or on the motion of
the Department of Commerce, involve determinations by both the Commerce Department and the
USITC. The Department of Commerce determines whether the product under investigation is
dumped, that is, sold in the United States at less than fair value, or subsidized by a foreign
government, while the USITC determines whether the dumped or subsidized imports cause
material injury or threat of material injury to a domestic industry. If dumping and injury are
found, antidumping duties will be imposed on imports of the product under investigation in the
amount of the dumping margin. If subsidization and injury are found, countervailing duties will
be imposed on the imported good in the amount of the net subsidy conferred.
In the event of an adverse WTO decision involving one of the above-described DOC or ITC
determinations, § 129 requires that, upon USTR request, the affected agency must first determine
if it may take action to comply with the WTO decision under existing law. If it finds that it may
do so, the USTR may request the agency involved to issue a determination—referred to by the
Commerce Department as a “Section 129 Determination” and the USITC as a “Section 129
Consistency Determination”—that would render the agency’s action “not inconsistent with the
findings” of the WTO panel or Appellate Body.22 The statute also requires consultation with
Congress at various stages of the implementation process.
Where an antidumping or countervailing duty order is no longer supported by an affirmative
injury determination—that is, where the USITC no longer finds material injury or threat from the
dumped or subsidized imports—the USTR may direct DOC to revoke the order in whole or in
part. Where a new DOC determination is issued, the USTR may direct DOC to implement the
new determination in whole or in part. Depending on the new DOC finding, DOC may raise or
lower the amount of duties to be collected on the subject imports under the order or, where
dumping or subsidization is no longer found or is found to occur at a statutory de minimis level,
DOC may revoke the order.
Section 129 determinations have prospective application, that is, they apply to unliquidated goods
(i.e., goods for which final duties have not been assessed) that enter the United States for
consumption on or after specified dates. These are as follows: (1) where a USITC material injury
determination no longer supports an antidumping or countervailing duty order, the date that the
USTR directs the Commerce Department to revoke the order, and (2) where a new DOC dumping

or subsidy determination is made, the date on which the USTR directs the Commerce Department
to implement the determination.23
Section 129 determinations that are implemented are reviewable in the U.S. Court of International
Trade or before binational panels established under Chapter Nineteen of the North American Free
Trade Agreement (NAFTA).24 As noted in the Uruguay Round Statement of Administrative
Action, “Section 129 determinations that are not implemented will not be subject to judicial or
binational panel review, because such determinations will not have any effect under domestic
law.”25
Judicial Responses
Although private rights of action based on Uruguay Round agreements are precluded under §
102(c) the URAA, WTO panel findings have at times been brought to the attention of federal
courts, most often in challenges to agency determinations in antidumping and countervailing duty
proceedings brought under judicial review provisions contained in § 516A of the Tariff Act of
1930, 19 U.S.C. § 1516a. Section 129 determinations issued by the USITC and the Commerce

23 URAA, § 129(c)(1), 19 U.S.C. § 3538(c)(1). See also Corus Staal BV v. United States, 593 F.Supp.2d 1373, 1378-80
(Ct. Int’l Trade 2008); Corus Staal BV v. United States, 515 F.Supp.2d 1337, 1346-47 (Ct. Int’l Trade 2007).
Regarding prospective application, the SAA states as follows: “Consistent with the principle that GATT panel
recommendations apply only prospectively, section 129(c)(1) provides that where determinations by the ITC or
Commerce are implemented under subsections (a) or (b), such determinations have prospective effect only.… Thus,
relief available under subsection 129(c)(1) is distinguishable from relief available in an action brought before a court or
a NAFTA binational panel, where, depending on the circumstances of the case, retroactive relief may be available.
Under 129(c)(1), if implementation of a WTO report should result in the revocation of an antidumping or
countervailing duty order, entries made prior to the date of the Trade Representative’s direction would remain subject
to potential duty liability.” Uruguay Round SAA, supra note 4, at 1026. See also Andaman Seafood Co. v. United
States, 675 F.Supp.2d 1363, 1369-73 (Ct. Int’l Trade 2010); Corus Staal BV v. United States, 593 F.Supp.2d 1373,
1378-80 (Ct. Int’l Trade 2008); Corus Staal BV v. United States, 515 F.Supp.2d 1337, 1346-47 (Ct. Int’l Trade 2007).
Regarding the scope of binational panels convened under North American Free Trade Agreement (NAFTA), see infra
note 24.
The extent to which the implementation dates in § 129(c)(1) permit the United States to comply with adverse decisions
in WTO dispute settlement proceedings was at issue in Canada’s unsuccessful WTO challenge of the provision in 2001.
Panel Report, United States—Section 129(c)(1) of the Uruguay Round Agreements Act, WT/DS221/R (July 15, 2002).
Canada did not appeal, and the panel report was adopted by the WTO Dispute Settlement Body in August 2002.
24 Tariff Act of 1930, as amended, §§ 516A(a)(2)(B)(vii), 516A(g)(1)(B); 19 U.S.C. §§ 1516a(a)(2)(B)(vii),
1516a(g)(1)(B). For further discussion of the relationship of a Section 129 determination to pending litigation in U.S.
courts over the final antidumping or countervailing duty determination that is the subject of the Section 129
determination, see Uruguay Round SAA, supra note 4, at 1027.
NAFTA Chapter Nineteen arbitral panels are available to review final domestic agency determinations in antidumping
and countervailing duty proceedings involving imports from NAFTA countries in lieu of judicial review in the country
in which the determinations are made. A NAFTA panel stands in the place of a U.S. court and is to apply the standard
of review and “general legal principles” that a U.S. court would apply in reviewing the antidumping or countervailing
duty determination before it. NAFTA arts. 1904.2, 1904.3, 1911 (definition of “standard of review”), annex 1911. In
contrast to the URAA authorities and requirements for implementation of WTO decisions, where a NAFTA panel
makes a decision remanding a determination to the Department of Commerce or the USITC, federal law directs
the agency involved to “take action not inconsistent with the decision….” Tariff Act of 1930, as amended,
§ 516A(g)(7)(A), 19 U.S.C. § 1516a(g)(7)(A). A NAFTA panel decision may be appealed to a NAFTA Extraordinary
Challenge Committee (ECC) on grounds set out in the agreement. NAFTA, art. 1904.13. A U.S. court is not bound by a
final binational panel or ECC decision, but “may take into consideration” any such decision in deciding the case before
it. Tariff Act of 1930, as amended, § 516A(b)(3), 19 U.S.C. § 1516a(b)(3).

World Trade Organization (WTO) Decisions and Their Effect in U.S. Law

Department to comply with WTO decisions are also reviewable under this statute. These cases are
heard in the U.S. Court of International Trade (USCIT), which has exclusive jurisdiction over
civil actions brought under § 516A.26 The USCIT’s decisions may be appealed to the U.S. Court
of Appeals for the Federal Circuit, whose decisions are reviewable by the U.S. Supreme Court.
Federal courts must hold a final agency determination in an antidumping or countervailing duty
proceeding or a Section 129 Determination unlawful if it is found to be “unsupported by
substantial evidence on the record, or otherwise not in accordance with law.”27 To determine
whether an agency determination is in accordance with law, the court employs the two-step
analysis for review of agency implementation of a statutory provision set out by the U.S.
Supreme Court in Chevron, U.S.A., Inc. v. Natural Resources Defense Council, 467 U.S. 837
(1984).28 First, the court, using tools of statutory construction, determines whether Congress has
clearly spoken to the issue at hand. Second, if the underlying statute is silent or ambiguous, the
court decides whether the agency’s construction of the statute is permissible and will defer to an
agency’s interpretation of a statute provided it is reasonable. It has also been argued that, in
considering whether an agency construction is reasonable, the court should apply the canon of
construction articulated by the Supreme Court in 1804 in Murray v. Schooner Charming Betsy, 6
U.S. (2 Cranch) 64, 118 (1804), namely, that where a statute does not require a specific
interpretation, that is, it permits more than one interpretation, it should be interpreted consistently
with U.S international obligations,29 in this context, a provision of a WTO agreement either by
itself or as interpreted in one or more WTO decisions.30 When read with Chevron, the Charming
Betsy
argument would come into play only where a statute is unclear as to the matter at hand;
where the statute is unambiguous, the statutory language prevails and the question of international
obligation would no longer be pertinent.
Because the underlying cause of action in domestic legal challenges to the agency actions
described above is based in the Tariff Act and not on a provision of a WTO agreement, courts
have not viewed § 102(c) of the URAA as preventing them from hearing a WTO-based argument
in these challenges.31 When faced with such arguments, some federal courts have deemed WTO

29 The Charming Betsy canon stems from the following Supreme Court language: “It has also been observed, that an act
of congress ought never to be construed to violate the law of nations, if any other possible construction remains, and
consequently, can never be construed to violate neutral rights, or to affect neutral commerce, further than is warranted
by the law of nations as understood in this country.” Murray v. Schooner Charming Betsy, 6 U.S. (2 Cranch) 64, 118
(1804).

decisions to be “persuasive”32 or a source of useful reasoning, “if sound,” to inform a court’s
decision,33 but have stated that WTO decisions are not binding on the United States, U.S.
agencies, or the judiciary.34 More commonly, however, federal courts have made clear that, given
the statutory scheme established in the URAA for implementing adverse WTO decisions,
questions as to whether the United States should comply with an adverse WTO decision and what
the extent of U.S. compliance should be are matters falling within the province of the executive
branch.35 As a result, in ruling on whether an agency action is reasonable, courts have declined to
base their decision making on a WTO decision adverse to the United States where the executive
branch has not taken the necessary domestic action to comply.36
The issue of the interaction of Chevron and Charming Betsy appears to have arisen most
frequently in court cases challenging Commerce Department antidumping determinations in
which dumping margins were calculated with the use of “zeroing,” a practice under which the
department considers only sales below fair market value—generally the price in the exporting
country—and assigns a zero value to sales at or above this price. The U.S. practice, which is
alleged to improperly create or inflate dumping margins, has been successfully challenged in
numerous WTO dispute settlement proceedings as violative of the WTO Antidumping
Agreement.37 At the same time, U.S. courts, using the Chevron standard of review, have regularly
held that, although the U.S. antidumping statute does not unambiguously require zeroing, the
Commerce Department’s interpretation of the statute as allowing the practice is a permissible
one.38 To respond to these adverse WTO decisions, the Commerce Department used § 123(g)

Court of Appeals for the Federal Circuit held that a classification opinion of the World Customs Organization “is not
binding and is entitled, at most, to ‘respectful consideration’” by a U.S. court. 454 F.3d 1361, 1366 (Fed. Cir. 2006).

Appellate Body decision faulting the U.S. practice, stating that such an amendment would be futile “given that it is not

Department.” See also Interactive Media Entertainment & Gamin Assn v. Gonzales, 2008 WL 5586713 (D.N.J.

authority to prospectively abandon the practice in original antidumping investigations in early
200739 and has recently proposed modifications in the use of zeroing in subsequent phases of U.S.
antidumping proceedings.40 In addition, where a specific antidumping order has been challenged
in a WTO proceeding, the Commerce Department has utilized § 129(c) authority to issue a new
antidumping determination in which the dumping margin was calculated without the use of
zeroing and, as a result, has either amended or, in some cases, revoked the antidumping order
involved.

(...continued)
U.S. law, a NAFTA binational panel, with two dissenting panelists, issued a decision in April 2010 in which it
remanded an antidumping determination to the Department of Commerce (DOC), directing it to recalculate the
dumping margin involved without employing the practice. NAFTA Panel Determination, Stainless Steel Strips and Coil
from Mexico
, USA-MEX-2007-1904-1 (April 14, 2010) [hereinafter Stainless Steel from Mexico], at
http://registry.nafta-sec-alena.org/cmdocuments/edce701c-9720-424b-b232-1fd714d318ba.pdf. The NAFTA panel
found that a “plain reading” of the U.S. antidumping statute—that is, the statutory definition of “dumping margin” and
a related term in 19 U.S.C. § 1677(35)—did not permit DOC to ignore non-dumped sales. Citing the Charming Betsy
canon, the panel further found that even if an interpretation is permissible under Chevron, it may be contrary to law for
Chevron purposes if it conflicts with a U.S. international obligation, here the requirements of the WTO Antidumping
Agreement. The panel further found that the provisions of the Uruguay Round Agreements Act addressing
implementation of WTO obligations—namely, § 102(a), setting out the relationship of U.S. law and WTO obligations,
as well as §§ 123(g) and 129—did not preclude the panel from in effect directing implementation of a U.S. WTO
obligation itself. Finally, the panel found that prior federal appellate court decisions upholding the use of zeroing,
which the DOC argued were binding on the panel, did not preclude a remand. The panel found that there were two
competing lines of U.S. cases on the issue of the relevance of WTO jurisprudence to judicial review, one permitting
courts to consider WTO jurisprudence in interpreting statutes and the other signaling a “retrenchment” from this
approach. Considering the issue to be “not presently reconciled” at the federal level, the panel found that it was
permitted it to look to international jurisprudence for guidance. Moreover, it found that it was not bound by the federal
appellate courts’ reasoning as to zeroing in the cases cited by the DOC on the ground that these cases were
distinguishable from the case at hand. The department issued a remand determination without zeroing in August 2010,
but filed the remand under protest, vigorously disagreeing with the panel’s decision. Remand Determination Pursuant
to NAFTA Panel:

Determination
], at http://insidetrade.com//index.php?option=com_iwpfile&file=sep2010/wto2010_2643.pdf. The
NAFTA panel has not yet issued its report on the new determination.
If the United States is ultimately displeased with the results of a NAFTA binational panel proceeding, it may seek
review of the panel decision before a NAFTA Extraordinary Challenge Committee. The United States may claim, for
example, that the panel has “manifestly exceeded its power, authority or jurisdiction, for example by failing to apply
the appropriate standard of review” and must allege as well that the cited action “has materially affected the panel’s
decision and threatens the integrity of the binational panel review process.” NAFTA art. 1904.13(a)(3), (b). The
Commerce Department in fact cited these concerns in its remand determination. Remand Determination, supra, at 3. In
a court case challenging a different DOC antidumping determination, the U.S. Court of International Trade recently
declined to consider the NAFTA panel decision in Stainless Steel from Mexico, an action permitted under 19 U.S.C.
§ 1516a(b)(3), stating that “any ‘consideration’ of the panel decision could not overcome the precedent binding on this
court, under which Commerce has statutory authority to apply the zeroing methodology ….” NSK Ltd. v. United
States, No. 10-00288, slip op. at 7-8 (Ct. Int’l Trade October 15, 2010), at http://www.cit.uscourts.gov/slip_op/

World Trade Organization (WTO) Decisions and Their Effect in U.S. Law

Recent Legislation
Legislation introduced in recent Congresses generally reflected congressional concerns that the
WTO Appellate Body had interpreted WTO agreements in an overly broad manner to the
detriment of the United States and that the executive branch had in some cases too readily used
existing statutory authorities to comply with these decisions, particularly where U.S. trade
remedies were involved. Legislation particularly focused on the various WTO disputes in which
the U.S. use of zeroing in antidumping proceedings was successfully challenged and the U.S.
response to one of the first WTO decisions on this issue, discussed earlier in this report.
111th Congress Legislation
H.R. 496 (Rangel) provided that the regulatory modification involving zeroing implemented by
the Commerce Department in 2007 in response to the adverse WTO decision faulting the U.S.
practice would expire March 1, 2009, and the prior departmental practice would thenceforth
apply, unless and until the department issues a revised methodology pursuant to procedures laid
out in the bill.41

41 The following bills were introduced in the 110th Congress: S. 364 (Rockefeller), which would have amended
§ 123(g) of the URAA to require that any regulatory modification or final rule proposed to implement an adverse WTO
decision be approved through joint resolution enacted into public law using an expedited legislative procedure; required
the USTR, after any adverse dispute finding, to work within the WTO to seek clarification of U.S. WTO obligations
under the agreement at issue and under certain circumstances prohibit the executive branch from modifying an
administrative measure in order to comply with the adverse WTO decision; rescinded certain administrative
compliance actions already in effect; and established a Congressional Advisory Commission on WTO Dispute
Settlement to review WTO decisions in light of enumerated statutory criteria; H.R. 708 (English), which, like S. 364,
would also have established a Congressional Advisory Commission on WTO Dispute Settlement; H.R. 2714 (Barrett),
which would have required the President to delay or reverse the implementation of adverse WTO decisions regarding
the use of zeroing until the United States had negotiated clarifications in the WTO that the practice is permitted in all
phases of antidumping proceedings; and H.R. 6530 (Rangel), which contained the zeroing-related provision
reintroduced in H.R. 496, 111th Congress. No action was taken on any of these bills.
