Section 21 of the Arbitration and Conciliation Act, 1996: Commencement of Arbitral Proceedings

Section 21 of the Arbitration and Conciliation Act, 1996 specifies when arbitral proceedings commence in respect of a particular dispute. Unless the parties have agreed otherwise, commencement occurs on the date when the respondent receives a request that the particular dispute be referred to arbitration.

What Section 21 means

Section 21 creates a default rule. The parties may agree on a different mechanism or date for commencement. If they do not, three elements are central: there must be a request to refer a dispute to arbitration, the request must relate to the particular dispute sought to be arbitrated, and the request must be received by the respondent.

1. The request must invoke arbitration

A communication relied upon under Section 21 should clearly communicate that the sender seeks reference of the identified dispute to arbitration. Ordinary correspondence, negotiations or a demand for payment may not, by themselves, amount to commencement of arbitral proceedings unless the communication can properly be understood as a request to refer the dispute to arbitration.

2. The request must concern the particular dispute

Section 21 uses the expression "particular dispute". The notice should therefore identify, with reasonable clarity, the dispute or claims proposed to be referred. This is especially important where the contractual relationship has generated several distinct claims or disputes.

3. Receipt by the respondent is important

Under the statutory default rule, the relevant date is the date on which the respondent receives the request. Section 3 of the Act contains rules concerning receipt of written communications, subject to any agreement between the parties.

Supreme Court guidance on commencement and limitation

The Supreme Court has explained that the purpose of Section 21 is to specify when arbitral proceedings in respect of a dispute commence where the arbitration agreement does not provide otherwise. The Court has also linked this date directly with Section 43 and the law of limitation.

In BSNL v. Nortel Networks India Pvt. Ltd., the Supreme Court emphasised that a clear notice invoking arbitration in respect of the particular dispute must be issued within the applicable limitation period. Mere exchanges of letters or ongoing settlement discussions do not automatically stop limitation from running.

Practical requirements of a Section 21 arbitration notice

• Refer to the arbitration agreement: identify the contractual clause or agreement under which arbitration is invoked.
• Identify the dispute: briefly state the nature of the dispute and the principal claim or relief sought.
• Expressly request arbitration: make it clear that the dispute is being referred, or is requested to be referred, to arbitration.
• Follow the agreed appointment procedure: where applicable, propose or nominate an arbitrator in the manner required by the arbitration clause and Section 11.
• Use a provable method of delivery: retain reliable evidence showing when the request was received by the respondent.
• Check limitation before service: Section 21 does not revive a claim that was already barred before valid invocation.

Section 21 is distinct from constitution of the arbitral tribunal

Commencement under Section 21 does not necessarily mean that the arbitral tribunal has already been constituted or has entered upon the reference. The statutory commencement date serves a particular legal function, especially for limitation, while appointment of arbitrators is governed principally by the arbitration agreement and Section 11 of the Act.

Key takeaway

Unless the parties have agreed otherwise, arbitral proceedings for a particular dispute commence when the respondent receives the request to refer that dispute to arbitration. Because Section 43 connects this date with limitation, parties should invoke arbitration clearly, identify the dispute, follow the contractual notice procedure and preserve proof of receipt.

Note: This page provides general legal information. The validity and effect of an arbitration notice depend on the wording of the arbitration agreement, the facts of the dispute and the applicable limitation period.
