Executive Summary: Key Legal and Evidentiary Issues

• Tehama sought to set aside an arbitral award under Article 34 of the Model Law, alleging procedural unfairness.

• The dispute arose from a post-closing purchase price adjustment under an asset purchase agreement.

• Tehama argued it was denied a fair opportunity to present its case and that the award was contrary to public policy.

• The court found the arbitration was conducted fairly and in line with the parties’ agreed procedure.

• Tehama’s complaints amounted to dissatisfaction with the outcome rather than genuine violations of natural justice.

• The application was dismissed, affirming the arbitrator’s final and binding decision.

Background and arbitration dispute

Tehama Group Inc. sold its business to Pythian Services Inc. under an asset purchase agreement (APA). A key term of the deal was a purchase price adjustment based on a post-closing financial statement, designed to reflect net working capital. After closing, a dispute arose over the calculation of this adjustment. The APA provided for final and binding resolution through arbitration.

Tehama initiated arbitration, claiming that Pythian’s post-closing adjustment improperly reduced the purchase price. The parties agreed on an arbitrator and set out a specific procedure. During the process, both sides made submissions and filed financial expert reports. In June 2024, the arbitrator issued a final award rejecting Tehama’s position and siding with Pythian’s calculation.

Application to set aside the award

Unhappy with the outcome, Tehama applied to the Ontario Superior Court to set aside the arbitral award under Article 34(2) of the UNCITRAL Model Law, which governs international commercial arbitration in Ontario. Tehama alleged that the arbitrator failed to give it a fair hearing, did not adequately address its submissions, and misapplied the contract and applicable law. It also raised concerns about public policy and procedural fairness.

The court emphasized that the threshold for setting aside an arbitral award is high and requires a clear breach of natural justice or jurisdictional overreach. It rejected Tehama’s argument that it had no real opportunity to present its case, finding that it had ample chance to make written and oral submissions, present evidence, and reply to Pythian’s case.

Court’s analysis and findings

Justice Osborne carefully reviewed the arbitration record and found that the process adhered to procedural fairness and the parties’ agreed framework. The arbitrator provided reasons for rejecting Tehama’s accounting interpretations and adopted a commercially reasonable view of the APA’s language.

The court stressed that dissatisfaction with an arbitrator’s reasoning or conclusion does not constitute a ground for judicial intervention. The alleged errors were not jurisdictional and did not show any denial of the right to be heard. There was also no violation of public policy.

Outcome and implications

The court dismissed Tehama Group Inc.’s application to set aside the arbitral award and upheld the final and binding nature of the arbitrator’s decision in favour of Pythian Services Inc. The ruling confirms the Ontario courts’ strong deference to arbitral autonomy and the high bar for judicial interference under the International Commercial Arbitration Act. The award stands, and the purchase price adjustment remains as determined by the arbitrator.
