Multi-tier arbitration clauses can defer limitation until pre-reference steps fail; Final Bill claims were timely, reimbursement claim was not.

A multi-tier dispute resolution clause postpones the accrual of the right to arbitrate until the agreed negotiation and Chief Executive reference process fails, so limitation for invoking arbitration runs only from that contractual breaking point. On that basis, the Final Bill claims were treated as within limitation because the pre-reference process failed on 21.12.2012 and arbitration was invoked on 27.01.2014 within three years. By contrast, the reimbursement claim for supplier payments stayed time-barred because no sufficient factual basis showed postponement or extension of limitation, and the dispute was not pursued within the permissible period.

Issues: (i) whether the claims included in the Final Bill were barred by limitation when the contract required prior negotiation and reference to the Chief Executives before arbitration; (ii) whether the claim for reimbursement of supplier payments was within limitation.

Issue (i): whether the claims included in the Final Bill were barred by limitation when the contract required prior negotiation and reference to the Chief Executives before arbitration.

Analysis: The dispute resolution clause required the parties to first attempt mutual negotiation and, failing that, refer the dispute to their Chief Executives before invoking arbitration. In a multi-tier dispute resolution mechanism, the right to seek arbitration arises only after the agreed pre-reference procedure is exhausted. Limitation for referring disputes to arbitration therefore does not begin to run before the parties reach the contractual breaking point and the pre-arbitral process has failed. On the facts, the reference to the Chief Executives failed on 21.12.2012 and arbitration was invoked on 27.01.2014, which was within three years. The contrary view treated the claims as time-barred from the date of bill certification and failed to account for the contractual precondition to arbitration.

Conclusion: The claims in the Final Bill were not barred by limitation and the rejection of Claims I, II and III on that ground was set aside in favour of the appellant.

Issue (ii): whether the claim for reimbursement of supplier payments was within limitation.

Analysis: This claim depended on invoices dated between 26.05.2007 and 30.06.2008. No sufficient factual basis was shown for postponing or extending the limitation period in respect of this claim, and no timely escalation of the dispute was demonstrated within three years of the cause of action. The contractual dispute-resolution steps were not pursued for this head of claim within the permissible period.

Conclusion: The claim for reimbursement of supplier payments remained barred by limitation and was not disturbed.

Final Conclusion: The appeal succeeded substantially, with the limitation ruling against the appellant reversed for the Final Bill claims, while the reimbursement claim was left undisturbed.

Ratio Decidendi: Where an arbitration clause prescribes negotiation and other pre-reference steps as a condition precedent, limitation for invoking arbitration begins only when that pre-reference procedure fails and the right to refer the dispute to arbitration accrues.
