Commercial Arbitration Act 2017

(Model Law art 4)

A party who knows that any provision of this Act from which the parties may derogate or any requirement under the arbitration agreement has not been complied with and yet proceeds with the arbitration without stating the party’s objection to such non‑compliance without undue delay or, if a time-limit is provided for stating the party’s objection, within such period of time, is taken to have waived the party’s right to object.
