Case Summary: Supreme Court (Commercial Circuit A) Contestation 113/2021 (Arbitration Award Nullified for Forming the Tribunal Contrary to the Agreed Rules)

The Supreme Court held that an arbitration award is null if the tribunal is formed in a manner contrary to the procedure the parties agreed to in their contract, even where the formation complied with the default procedure of the Arbitration Law. Because the contract is the law of the parties, setting aside the agreed arbitration rules is equivalent to setting aside the law itself under article 53(1)(e) of the Arbitration Law.
