Arbitration and Conciliation Act, 1996 · Chapter III

Section 15: Termination of mandate and substitution of arbitrator

In plain words

An arbitrator's mandate also ends if they withdraw for any reason or the parties agree. A substitute is appointed under the same rules as the original.

  • The tribunal may repeat earlier hearings.
  • Earlier orders remain valid despite the change of arbitrator, unless the parties agree otherwise.
