WTO Dispute Settlement: Stages and
Pending U.S. Activity Before the
Dispute Settlement Body
Todd B. Tatelman
Legislative Attorney

Summary
World Trade Organization (WTO) member countries resolve disputes pursuant to
the WTO Dispute Settlement Understanding (DSU), which establishes the Dispute
Settlement Body (DSB) to administer dispute proceedings and contains the rules and
procedures that apply to these proceedings. Since the inception of the DSU in January
of 1995, there have been 324 complaints filed. Of these complaints, the United States
has been actively involved, either as a complainant or defendant, in slightly more than
half, or 167 of these cases. This report briefly describes the various stages of the WTO
dispute settlement process, and provides a statistical overview of the pending cases in
which the United States is a party. This report will be updated.
Stages of a WTO Dispute1
Consultations.2 When a dispute arises between WTO member countries, the
complaining party may request that the other nation(s) enter into consultations to attempt
to resolve the dispute. Consultations are required to be active for a period of 60 days
before the complaining party can request the formation of a panel to resolve the dispute.
If, however, the responding party fails to agree to consultations, or the parties agree that
the dispute cannot be settled in consultations, then a panel may be requested before the
expiration of the 60 days.

Establishment of Panel and Panel Procedures.3 If a member party requests
that the DSB establish a panel, the DSB must establish the panel unless there is a
consensus not to do so. Panels are usually composed of three members who are proposed
by the DSB Secretariat and approved by the disputing parties. If no agreement over panel
members can be reached within 20 days of the panel’s establishment, either party may
request that the WTO Director General appoint the members of the panel.
Once the members have been selected, the panel receives written submissions from
the parties and hears oral arguments. The panel then has six months, unless an extension
is granted, to issue a final report to the disputing parties. The panel report is then
circulated to the WTO membership for adoption. The time period from establishment of
a panel to circulation of the final report should not exceed nine months.
Appellate Review.4 The panel report is to be adopted within 60 days of circulation
to WTO members, unless a disputing party issues a notice of appeal. If a notice has been
issued, the Appellate Body (AB) has 60 days to issue a report that either affirms, reverses
or modifies the panel report. The appellate report is then circulated to the WTO
membership who must adopt it, along with the original panel report as modified by the
AB report, unless there is a consensus not to do so.
Implementation and Compliance.5 After the adoption of either a final panel
or appellate report, a member will have 30 days to notify the DSB as to how the findings
of the report will be implemented. Implementation, however, often cannot be achieved
quickly, so a reasonable period of time is provided to the country for implementation. If
a dispute arises as to how long a reasonable period of time should be, the compliance
period will be determined by binding arbitration. If there is a dispute as to whether
implementation or compliance has been achieved, the parties may also seek to settle the
dispute through binding arbitration. If an arbitration panel is established to settle a
dispute over implementation or compliance, it generally has 90 days to complete its report
and issue its findings.

Pending U.S. Activity Before the DSB6
The following chart is compiled from documents produced by the WTO, and reports
only the cases that involve the United States.7 The table does not indicate the outcome
on the merits with respect to any of the reported cases, except for noting the number of
cases in the implementation phase.8
6 World Trade Organization, Update of WTO Dispute Settlement Cases, WT/DS/OV/22 (Oct. 14,
2004), available at [http://www.wto.org]. According to the most current chronological list of
disputes maintained by the WTO, there has been a total of 324 complaints filed since the
inception of the DSU on January 1, 1995. See WTO, Disputes Chronologically, available at [
http://www.wto.org/english/tratop_e/dispu_e/dispu_status_e.htm] (last visited Jan. 6, 2005).
In addition, the Office of the United States Trade Representative (USTR) publishes a report
that provides a statistical breakdown of WTO disputes involving the United States, however,
USTRs report is divided based on the stages of the WTO dispute settlement process, as well
as the general outcome of proceedings involving the United States. See USTR, Snapshot of
WTO Cases Involving the United States, (Dec. 3, 2004), available at
[http://www.ustr.gov/assets/Trade_Agreements/Monitoring_Enforcement/Dispute_Settlement
/WTO/asset_upload_file306_5696.pdf]. According to the USTR report, the U.S. has filed 75
complaints and been a respondent in 99 cases. Id.

2004), available at [http://www.wto.org].
8 The table provides a breakdown of only the cases that are actively pending. The figures
reflecting the total number of cases filed includes the active cases, as well as cases that have
completed the dispute settlement process and/or have been concluded in a manner mutually
agreeable to the parties.

a. This figure reflects all requests for consultations that were notified to the WTO as of Dec. 31, 2004
including WT/DS317 US – Measures Affecting Trade in Large Civil Aircraft; WT/DS320 US – Continued
Suspension of Obligations in the EC – Hormones Dispute; WT/DS322 US – Measures Relating to Zeroing
and Sunset Reviews; and WT/DS324 US – Provisional Antidumping Measures on Shrimp from Thailand.
See WTO, Disputes Chronologically, available at [http://www.wto.org/english/tratop_e/dispu_e/dispu_st]
atus_e.htm (last visited Jan. 6, 2005).
b. This figure includes all cases in which panels have been established by the DSB, even cases where panels
have not been constituted.
c. The Panel Reports include WT/DS281 US – Measures Relating to the Cross-Border Supply of Gambling
and WT/DS267 US-Upland Cotton.
d. According to WTO Documents, the United States has notified its intent to appeal in WT/DS281 US –
Measures Relating to the Cross-Border Supply of Gambling.
e. Currently, in five of these cases legislative action appears to be required to bring the United States into
full compliance with the rulings of the DSB: WT/DS160 Section 110(5)(B) of the Copyright Act;
WT/DS176 Section 211 of the Omnibus Appropriations Act of 1998; WT/DS 184 Hot-Rolled Steel
Products from Japan; WT/DS217/234 Continued Dumping and Subsidy Offset Act; and WT/DS268 US –
Oil Country Tubular Goods Sunset Reviews. In the remaining cases, administrative action could be required
to bring the United States into compliance: WT/DS264 US – Final Dumping Determination on Softwood
Lumber from Canada. See CRS Report RL32014, WTO Dispute Settlement: Status of U.S. Compliance in
Pending Cases, by Jeanne Grimmett.
f. The 108th Congress enacted legislation to repeal the non-compliant measures in both WT/DS108 Foreign
Sales Corporation (FSC) Statute and WT/DS136/162 Antidumping Act of 1916, however, because our
actions are still subject to review by the DSB at the request of the affected countries, the disputes are still
considered to be active. In addition, administrative action has been taken in the following cases: WT/DS212
European Communities- Countervailing Measures Concerning Certain Products; WT/DS257 US – Final
Countervailing Duty Determination with Respect to Certain Softwood Lumber from Canada; and
WT/DS277 US – Investigation of the International Trade Commission in Softwood Lumber from Canada.
It remains to be seen, however, whether these measures will actually result in termination of the respective
disputes. See CRS Report RL32014, WTO Dispute Settlement: Status of U.S. Compliance in Pending
Cases, by Jeanne Grimmett.
