MPIA
"Interim WTO appellate review mechanism established in 2020 by 26+ members after the WTO Appellate Body went dysfunctional."
The Multi-Party Interim Appeal Arbitration Arrangement (MPIA) is a stop-gap mechanism set up under Article 25 of the WTO Dispute Settlement Understanding (DSU) to provide binding appellate-style review while the WTO Appellate Body remains paralysed. The Appellate Body has been non-functional since December 11, 2019, when the United States blocked the appointment of new members, leaving its membership below the quorum of three required to hear appeals. To prevent disputes from being appealed 'into the void', the European Union and a group of like-minded WTO Members notified the MPIA on March 27, 2020 (formally circulated as JOB/DSB/1/Add.12). It uses retired Appellate Body members as arbitrators and follows AB-like procedures. Today over 26 WTO Members participate (EU counted as one), including China, Canada, Australia, Brazil, Japan, Switzerland, the UK, and most ASEAN economies. India, the United States, Russia, and South Korea are NOT participants — a fact that shapes India's choices when its disputes are appealed.
Directly relevant to GS2 (international institutions, WTO reform) and GS3 (external sector, trade remedies). Prelims may ask about Article 25 DSU, year of AB collapse, or India's non-membership. Mains may ask about the future of multilateral dispute settlement and India's stance.
- 1 Stop-gap appellate mechanism under Article 25 of the WTO Dispute Settlement Understanding (DSU)
- 2 Notified March 27, 2020 by the EU and partners after the Appellate Body went dysfunctional on December 11, 2019
- 3 26+ WTO Members participate; India, the US, Russia, and South Korea remain outside
- 4 Uses a pool of 10 standing arbitrators (often retired AB members); decisions are binding inter-se
- 5 Operates only between consenting parties — cannot bind non-participants such as the US or India
- 6 Linked to broader 'MC13 DSU reform' track aimed at restoring a fully functioning two-tier WTO system by 2024 deadlines that lapsed
- 7 Common Prelims hook: distinguish MPIA from the Appellate Body and from arbitration under Article 21.5/22 DSU
When India blocked China's request for a WTO panel on India's solar tariffs and ALMM at the Geneva DSB on May 22, 2026, analysts noted that India's non-participation in MPIA limits its options if China later seeks appellate-style review of any future panel ruling.
