The First MPIA Appeals?

The WTO has just posted three sets of agreed procedures for arbitration under DSU Article 25, that is to say, procedures for appeals through the Multi-Party Interim Appeal Arbitration Arrangement (MPIA). The cases involved are Canada - Sale of Wine (DS537), Costa Rica - Avocados (DS524), and Canada - Aircraft (DS522). The latest info I see is that in DS537, issuance of the final report to the parties is scheduled for June 4, 2020 (WT/DS537/11/Add.3); in DS524, the panel expects to issue its final report to the parties by the second half of 2020 (WT/DS524/4); and in DS522, the panel's work was suspended effective November 25, 2019 until November 4, 2020 under DSU Article 12.12 (WT/DS522/19).
