A party dragged into arbitration often wants to argue that the tribunal has no business hearing the dispute at all: the arbitration agreement does not exist, is invalid, or does not cover the claims made. Section 16 of the Arbitration and Conciliation Act, 1996 answers a threshold question about that objection: who decides it? The answer, known as the kompetenz-kompetenz principle, is that the arbitral tribunal itself is competent to rule on its own jurisdiction, with court scrutiny reserved for defined stages.
What Section 16 says
Section 16(1) of the Arbitration and Conciliation Act, 1996 provides that the arbitral tribunal may rule on its own jurisdiction, including ruling on any objections with respect to the existence or validity of the arbitration agreement. The provision then adds two propositions that carry the principle of separability:
- An arbitration clause which forms part of a contract is treated as an agreement independent of the other terms of the contract.
- A decision by the tribunal that the contract is null and void does not entail, by itself, the invalidity of the arbitration clause.
The arbitration clause is thus a contract within a contract. Even if the main contract is attacked as void, the clause survives as an independent agreement, and the tribunal constituted under it can examine the attack. Without this rule, every allegation against the main contract would automatically pull the dispute out of arbitration and into court, defeating the bargain to arbitrate.
Timing of jurisdictional pleas
Section 16 fixes when the objection must be raised, and the timelines are strict:
Plea of no jurisdiction
A plea that the tribunal does not have jurisdiction must be raised not later than the submission of the statement of defence. Participating in the appointment of the arbitrator does not preclude a party from raising the plea.
Plea of exceeding scope
A plea that the tribunal is exceeding the scope of its authority must be raised as soon as the matter alleged to be beyond the scope of its authority is raised during the proceedings.
Condonation of delay
The tribunal may admit a plea raised later than these points if it considers the delay justified. Condonation is discretionary, so a respondent should treat the statement of defence as the outer limit and plead the objection there.
The discipline serves a purpose. A party cannot keep a jurisdictional objection in its pocket, test its luck on merits, and produce the objection only if the case goes badly. The objection is either raised at the threshold or, absent justification for the delay, lost.
Two routes after the ruling
Section 16(5) directs the tribunal to decide a plea of lack of jurisdiction or excess of scope and, where it rejects the plea, to continue with the arbitral proceedings and make an award. The consequences then divide sharply depending on which way the ruling goes.
Plea rejected: continue, challenge later
If the tribunal rejects the objection and holds that it has jurisdiction, the arbitration proceeds. The Act deliberately provides no immediate appeal against that rejection. The objecting party must carry on with the arbitration, and its remedy is preserved for the end: under Section 16(6), a party aggrieved by the eventual award may apply to set it aside in accordance with Section 34, and the jurisdictional objection can be pressed there. The design prevents jurisdictional skirmishes from freezing the arbitration midway.
Plea accepted: immediate appeal
If the tribunal accepts the plea and holds that it lacks jurisdiction, the proceedings end without an award on merits. Because that outcome would otherwise leave the claimant remediless on an unreviewed ruling, the Act provides an immediate appeal: Section 37(2)(a) makes an order of the tribunal accepting the plea under Section 16(2) or 16(3) appealable to the court. The asymmetry is intentional. A ruling that keeps the arbitration alive is reviewed only after the award; a ruling that kills it is reviewed at once.
Minimal judicial interference
Section 16 works in tandem with Section 5 of the Act, which provides that, notwithstanding anything contained in any other law, no judicial authority shall intervene in matters governed by Part I except where the Part so provides. Read together, the two provisions channel jurisdictional disputes to the tribunal first and confine court scrutiny to the openings the Act itself creates, chiefly the Section 37(2)(a) appeal and the Section 34 challenge. Collateral attempts to have courts rule on the jurisdiction of a functioning tribunal sit uneasily with this scheme.
The same philosophy shapes the appointment stage. When a court is approached under Section 11 for appointment of an arbitrator, its examination is confined to a narrow threshold look at the matter, and contested jurisdictional questions, including disputes about the validity or scope of the arbitration agreement, are ordinarily left to be decided by the tribunal itself under Section 16.
Practical pointers
For respondents, the rule of thumb is to raise every jurisdictional objection in or before the statement of defence, in clear terms, and to invite a ruling under Section 16 rather than merely reserving rights. For claimants, an adverse Section 16 ruling is not the end of the road: the Section 37(2)(a) appeal exists precisely for that situation and should be pursued within limitation. And for both sides, a rejected objection is not extinguished; it is postponed to the Section 34 stage, so the record made before the tribunal on jurisdiction should be built with that eventual challenge in mind. Connected topics, including appointment under Section 11, interim measures and the scope of Section 34, are covered in separate explainers on this site.
Frequently Asked Questions
Can an arbitral tribunal decide whether the arbitration agreement is valid?
Yes. Section 16(1) empowers the tribunal to rule on its own jurisdiction, including any objections to the existence or validity of the arbitration agreement. For that purpose the arbitration clause is treated as an agreement independent of the rest of the contract, and a decision that the contract is null and void does not by itself invalidate the arbitration clause.
When must a party object that the tribunal lacks jurisdiction?
A plea that the tribunal does not have jurisdiction must be raised not later than the submission of the statement of defence, and a plea that the tribunal is exceeding the scope of its authority must be raised as soon as the matter alleged to be beyond scope arises. The tribunal may admit a later plea if it considers the delay justified. A party is not barred merely because it participated in appointing the arbitrator.
What happens if the tribunal rejects the jurisdictional objection?
The tribunal continues with the proceedings and makes its award. There is no immediate appeal against an order rejecting the plea. The aggrieved party must wait for the award and then raise the jurisdictional ground in an application to set aside the award under Section 34 of the Act.
What if the tribunal accepts the plea and holds it has no jurisdiction?
An order by which the tribunal accepts the plea that it lacks jurisdiction is appealable under Section 37(2)(a) of the Act. The claimant can therefore carry that decision to the court in appeal, since otherwise its claims would be left without a forum on the strength of an unreviewed tribunal ruling.
