Almost every seriously contested arbitration opens with the same question: is the tribunal even entitled to decide this dispute? A jurisdictional challenge is not a technicality on the margins of a case — it is a contest over the source of the tribunal's authority, and it engages two of the most elegant doctrines in the field: competence-competence and separability. Handled well, it is a scalpel. Handled late, the objection is simply lost.
Two doctrines that let arbitration begin
Arbitration is a creature of consent. A tribunal has power only because the parties agreed to give it power. That creates an obvious paradox: if a respondent says "there was never a valid agreement to arbitrate," who decides that question — the tribunal whose very existence is under attack, or a court? The law answers with two interlocking principles.
Competence-competence (Kompetenz-Kompetenz) holds that the tribunal itself has authority to rule on its own jurisdiction. The rationale is practical: without it, any reluctant party could stall proceedings for years simply by disputing the clause and running to court. The doctrine denies that delaying tactic. Critically, however, it is not the last word. Competence-competence gives the tribunal the first word; the supervising court retains the power to review that determination. The tribunal decides; the court, ultimately, controls.
Separability (or severability) supplies the doctrine that makes this coherent. The arbitration clause is treated as an agreement autonomous from the contract that contains it. So an attack on the main ("container") contract — that it was procured by fraud, is void, was terminated or rescinded — does not automatically defeat the arbitration clause. The clause survives to allow the very tribunal it creates to decide whether the surrounding contract stands or falls. Without separability, every challenge to the contract would collapse the mechanism meant to resolve it.
Competence-competence gives the tribunal the first word on its own jurisdiction; the court keeps the last.
The grounds of a jurisdictional objection
Jurisdictional challenges are not free-floating complaints; they cluster around a limited set of arguments. In practice a respondent will say one or more of the following:
- No valid or existent arbitration agreement — the clause was never concluded, is void, has expired, or was signed by someone without authority or capacity.
- A party outside the agreement — the claimant or respondent never signed, raising the difficult territory of non-signatories, group-of-companies arguments, assignment and agency.
- The dispute falls outside the clause's scope — the matter is real, but this particular claim is not one the parties agreed to submit.
- Non-arbitrability — the subject matter is one the law reserves to the courts (certain criminal, insolvency, real-property, family or public-policy matters), so no clause can validly send it to arbitration.
- Unfulfilled conditions precedent — multi-tier clauses requiring negotiation, mediation or a cooling-off period before arbitration; if those steps were skipped, the tribunal may not yet be validly seised.
Timing is everything: plead early or waive
The single most common way to lose a jurisdictional objection is to raise it too late. Arbitral rules and statutes require a plea of no jurisdiction to be made at the outset — typically no later than the statement of defence — and a narrower objection, that a specific issue exceeds the tribunal's mandate, to be raised as soon as that issue arises. A party that participates in the proceedings without objecting is generally taken to have accepted the tribunal's authority. Appointing an arbitrator does not, by itself, forfeit the right to object; but silence at the proper moment does. The message is unforgiving: object first, argue the merits second — never the reverse.
The tribunal's choice: preliminary question or joined to the merits
Once a jurisdictional plea is raised, the tribunal faces a strategic fork. It may rule on jurisdiction as a preliminary question, issuing a partial award that decides jurisdiction before touching the merits; or it may join the objection to the merits and resolve everything in the final award.
Each path carries trade-offs. A preliminary award is efficient where the objection is clean and potentially dispositive — why hear a two-year case if the tribunal has no power? It also allows early court review of the jurisdiction question. But bifurcation costs time and money if the objection ultimately fails, and it can hand a losing respondent an early route to court to delay. Joining to the merits avoids duplicated hearings where jurisdiction and substance overlap heavily, but forces the parties to litigate a full case that a court may later unwind on jurisdictional grounds. The decision is genuinely tactical, and experienced counsel weigh it deliberately.
The court's role: before, during and after
Competence-competence coexists with judicial control at three moments. Before, when a party sues in court despite an arbitration clause, the court is asked to stay its proceedings and refer the parties to arbitration — the "negative" face of competence-competence, under which courts conduct only a prima facie review and leave the deep jurisdictional analysis to the tribunal. During, court intervention is deliberately limited, confined to supportive functions and, where allowed, review of a preliminary jurisdiction ruling. After, jurisdiction becomes a ground to challenge the award itself — to set it aside at the seat, or to resist recognition and enforcement abroad. Under the New York Convention, Article V(1)(a) permits refusal where the arbitration agreement was invalid or a party lacked capacity, and Article V(1)(c) where the award decides matters beyond the scope of the submission. This is where competence-competence meets its ceiling: the tribunal ruled, but the court has the last word.
The UAE position
The Federal Arbitration Law (Federal Law No. 6 of 2018) adopts both doctrines squarely. Article 19 confers competence-competence: the tribunal may rule on its own jurisdiction, including objections that no arbitration agreement exists, is void, or does not cover the dispute, and may do so as a preliminary decision or in the final award. Where it rules as a preliminary matter that it has jurisdiction, a party may ask the court to decide the point within a short window after notification — a targeted, time-boxed judicial check. Article 6 enacts separability: the arbitration agreement is treated as independent of the other terms of the contract, and the nullity, rescission or termination of the contract does not affect a valid arbitration agreement, subject to questions of capacity.
Article 20 imposes strict timing: a plea that the tribunal lacks jurisdiction must be raised no later than the statement of defence, and a plea that a matter exceeds the scope of the arbitration must be raised promptly when it arises, failing which the right is waived — though the tribunal may admit a late plea if the delay is justified. Finally, Article 53 makes jurisdiction a ground to set aside an award, including where there was no valid arbitration agreement, a party lacked capacity, or the award dealt with matters outside or exceeding the scope of the agreement — mirroring the New York Convention grounds a UAE court would apply when asked to enforce a foreign award. For any party contemplating a jurisdictional challenge in the UAE, the practical discipline is the same everywhere: identify the ground precisely, and raise it on time.
