#waiver

The Delhi HC held that waiver of the right to object to an arbitrator’s appointment under Section 12(5) requires an express written agreement after the dispute; mere participation does not suffice. This clarifies the law for parties in arbitration.

Delhi High Court ruled Section 34 challenges to international commercial arbitral awards are limited to patent illegality, rejecting waiver-of-timeline arguments. The decision narrows judicial interference, reinforcing finality of cross-border awards. Parties must rely on these narrow grounds.
