French Annulment Decision confirms a pro arbitration approach by the Paris Court of Appeal and Affirms Arbitrators’ Authority to Refine and Order Effective Remedies
Arbitration analysis: Arbitrators’ authority to order specific remedies is not precluded by the broad wording of a claim, as held in substance by the Paris Court of Appeal in its decision of 13 January 2026. Under French law, the scope of arbitrators’ powers is limited by the subject matter of the dispute, which is in turn defined by the parties’ claims. Accordingly, a ruling ultra petita exposes the award to annulment. In this case, the court dismissed the application for annulment and upheld an ICC partial award, holding that the arbitral tribunal had not exceeded its powers by translating a request for good-faith performance and cooperation, subject to a per diem penalty (astreinte), into a more detailed order to execute an agreement and complete the related formalities, since these measures were provided for in the contract and had been addressed in the claimant’s submissions. This decision therefore confirms the discretion that arbitrators have when specifying the modalities of performance needed to give effect to the relief granted, even where these are not expressly requested, provided they remain consistent with the contract and the claims made.
