The Unilateral Extension
You chair a three-member tribunal seated in a Model Law jurisdiction. The parties' arbitration agreement incorporates institutional rules whose Article 27 provides that 'the arbitral tribunal may extend any time limit, save that the final award shall be rendered within twelve months of constitution, which period may be extended only by written agreement of the parties.' The tribunal was constituted on 3 February. On 20 January of the following year the tribunal issued a procedural order extending the deadline to 30 June, relying on its general case-management powers; neither party objected. The respondent has now discovered the order and, on 2 April, asks the tribunal to declare the proceedings terminated for want of jurisdiction, arguing that the extension was invalid and that the tribunal has been functus officio since 3 February. The claimant urges you to proceed and issue the award by 30 June. Neither party has applied to any court.
1. Identify the two competing characterisations of the tribunal's power to extend its own deadline, and explain which is correct on the wording of Article 27.

The competing readings are, first, that Article 27 confers a general power of extension exercisable by the tribunal unless the parties agree otherwise, and, second, that the twelve-month period is a hard ceiling that only the parties can lift.
The second reading is correct. Article 27 has two limbs. The first is a general power: the tribunal 'may extend any time limit'. The second is a specific carve-out: the final award must be rendered within twelve months, and that period 'may be extended only by written agreement of the parties'. The word 'only' is exhaustive. Where a general power and a specific exception sit in the same provision, the specific exception governs the case it addresses. The tribunal's general case-management powers therefore cannot reach the final-award deadline; that deadline is outside the tribunal's unilateral competence.
The consequence is that the 20 January order was made without power as regards the twelve-month period. The parties' silence is not written agreement: a failure to object is not the positive, documented consent the clause requires, and it cannot create a jurisdiction the rules withhold.
2. The respondent seeks a declaration that the proceedings are terminated. What is the tribunal's correct course, and what is the status of an award issued after 3 February?
Read the worked answer
The tribunal should not simply declare itself functus officio and terminate. Functus officio means the tribunal has discharged its function by rendering a final award; it does not describe a tribunal that has run out of time before doing so. Termination on the respondent's theory would be a jurisdictional ruling that disposes of the reference, and it would be wrong for two reasons.
First, the twelve-month period is a rule of the procedure the parties chose, not a limit on the tribunal's underlying jurisdiction derived from the parties' agreement to arbitrate. Breach of it is a procedural irregularity, not an absence of consent.
Second, the tribunal should invite the parties to cure the defect. Article 27 permits extension by the parties' written agreement at any time before the award is made. The tribunal should convene a short hearing, state plainly that the 20 January order could not extend the final-award date, and ask both parties to sign a written extension to 30 June. If both do so, the tribunal proceeds and the award is regular. If the respondent refuses, the tribunal should record the refusal and consider whether to seek the parties' agreement to a shorter timetable, or whether the respondent's conduct amounts to a waiver.
An award issued after 3 February without party agreement is exposed to a setting-aside or enforcement challenge as a procedural irregularity going to the tribunal's mandate. The tribunal should not knowingly create that exposure.
3. Assume the respondent refuses any extension and the claimant asks you to proceed. How do you weigh the competing risks, and what procedural step best protects the award?
Read the worked answer
The tribunal must weigh the risk of an award that is vulnerable to challenge against the risk of denying the claimant a determination on the merits. Neither is attractive, so the tribunal should reduce the exposure rather than gamble on it.
The best step is a reasoned procedural order that (i) records the tribunal's own analysis of Article 27, (ii) records that the 20 January order was ineffective as to the final-award date, (iii) records the respondent's refusal to extend, and (iv) invites the respondent to state any prejudice it would suffer from proceeding, with a short deadline. This creates a clear record for any reviewing court and gives the respondent a fair opportunity to be heard, which is itself a ground on which challenges are often defeated.
The tribunal should then consider whether the respondent's refusal, coupled with its earlier non-objection and its continued participation without seeking court relief, amounts to an implied waiver or estoppel. That argument is available but uncertain; the tribunal should not treat it as a licence to ignore the rule. A safer course is to press the parties toward a short written extension, even if only to a date the respondent can accept, and to explain that the alternative is a challenge that will cost both sides more than the extension.
If no extension is forthcoming and the claimant insists, the tribunal may proceed, but it should do so with a fully reasoned record and should not represent to either party that the timetable problem has been solved.
