Arbitral tribunals become functus officio once the final award is made — with one carefully bounded exception. Section 33 of the Arbitration and Conciliation Act, 1996 keeps the tribunal alive for a short period to correct clerical and computational slips, interpret specific parts of the award on agreed request, and make an additional award on claims presented but omitted. Used precisely, it repairs awards without litigation; used carelessly, it wastes limitation or invites a disguised review the tribunal has no power to grant. This article walks through the provision’s three limbs, its timelines, and its interaction with the Section 34 challenge period.
The three limbs at a glance
| Limb | Who may invoke | Time (from receipt of award) | Tribunal’s time to act |
|---|---|---|---|
| Correction of computation/clerical/typographical errors — s. 33(1)(a) | Any party, with notice to the other; tribunal may also correct suo motu within thirty days of the award — s. 33(3) | 30 days (extendable by agreement) | 30 days of receipt of request; extendable by the tribunal — s. 33(6) |
| Interpretation of a specific point or part — s. 33(1)(b) | A party, only if the parties agree | 30 days | 30 days; the interpretation forms part of the award |
| Additional award on omitted claims — s. 33(4) | A party, with notice to the other, unless otherwise agreed | 30 days | 60 days if the tribunal considers the request justified — s. 33(5) |
Section 33(7) applies the form-and-content requirements of Section 31 to corrections, interpretations and additional awards alike — reasons, signatures, delivery — so the output is itself an award, challengeable and enforceable as such.
Drawing the substantive line
Slip, not second thoughts. The correction power fixes the expression of the tribunal’s intention, never the intention itself. If the award says what the tribunal meant — however wrong a party thinks it — Section 33 offers nothing; the remedy is Section 34.
Ambiguity, not advocacy. Interpretation requests must target genuine obscurity in a specific part — an operative direction whose scope is unclear, a formula whose inputs are undefined. Consent of both parties is mandatory, and tribunals properly refuse requests that re-argue the merits under an interpretive label.
Omission, not dissatisfaction. The additional-award limb answers a real and recurring defect: a pleaded claim — interest, a costs head, one invoice among many — that the award simply fails to address. The test is presented-but-omitted; the cure is adjudication of the omitted claim, not enhancement of decided ones.
Strategic dimensions
Section 33 also polices tribunals’ own errors gently: the suo motu correction power under Section 33(3) lets a tribunal fix its slips within thirty days without waiting for the parties. Institutions increasingly scrutinise draft awards precisely to make both routes unnecessary — but the statutory safety net remains, and counsel should know its mesh exactly.
The takeaway
Section 33 is the cheapest remedy in the arbitration statute — measured in days and letters rather than years and court fees — but only for the defects it actually covers: slips, genuine ambiguities and omitted claims. The month after the award arrives should be spent with a calculator and the pleadings, deciding which of the award’s problems belong to the tribunal under Section 33 and which to the court under Section 34. Confusing the two wastes the only clock that never restarts.

Frequently Asked Questions
What can be corrected under Section 33(1)(a)?
Computation errors, clerical or typographical errors, and errors of a similar nature — the slip rule. Wrong totals, transposed figures, misdescribed parties or dates, arithmetic in interest calculations. What cannot be corrected is reasoning: a tribunal cannot, under the correction power, revisit findings, reweigh evidence or change the substance of what it decided.
What is the interpretation limb?
With the agreement of both parties, a party may ask the tribunal to give an interpretation of a specific point or part of the award; the interpretation, once given, forms part of the award. The consent requirement is the gate — a unilateral request for interpretation is incompetent, which keeps the limb from becoming a review by another name.
When can an additional award be sought?
Where claims were presented in the arbitral proceedings but omitted from the award, a party may — within thirty days of receiving the award, with notice to the other party — request an additional award. The tribunal, if it considers the request justified, makes the additional award within sixty days. The limb covers omitted claims, not omitted arguments: a claim decided badly is Section 34 territory; a claim not decided at all is Section 33(4) territory.
How does Section 33 affect the Section 34 limitation?
Section 34(3) runs limitation from the date of disposal of a Section 33 request where one has been made — the three-month period counts from the date the request is disposed of by the tribunal. A genuine Section 33 application therefore defers the challenge clock; but courts scrutinise colourable applications filed only to gain time, and a request outside Section 33’s scope may not earn the deferred start.
