Calling a tribunal’s jurisdictional determination an “award” does not necessarily open another appellate route.
In Grace v. United Mexican States, 2026 ONCA 700, the Ontario Court of Appeal quashed Mexico’s appeal from a Superior Court decision setting aside a NAFTA tribunal’s jurisdictional award. The court held that section 11 of Ontario’s International Commercial Arbitration Act, 2017 barred the appeal.
For arbitration counsel, the decision emphasizes the importance of identifying available court recourse before assuming that an adverse judicial decision can be appealed.
The dispute concerned jurisdiction
The arbitration tribunal found that it lacked jurisdiction. The claimants successfully sought to set aside its award in the Superior Court.
Mexico argued that the statutory appeal bar applied to preliminary jurisdictional rulings rather than awards. The Court of Appeal rejected that distinction in the circumstances, noting that the tribunal had not determined substantive liability or damages.
The decision therefore concerns a particular jurisdictional determination. It should not be described as eliminating appeals from every Ontario arbitration-related order.
Substance controls the appellate analysis
The important point is what the tribunal decided.
The form of a document may matter within an arbitration framework, but its label does not automatically settle the court’s authority to hear an appeal.
Counsel must examine the statutory language, the nature of the determination and the procedural route through which the matter reached court.
That analysis should happen early. An assumed appeal can distort strategy if the governing legislation makes the first judicial determination the final one at that level.
The first court proceeding carries greater weight
Where a further appeal is unavailable, counsel must prepare the initial court record with that finality in mind.
The legal argument needs to identify the precise basis for intervention. The evidentiary record must support the relief sought. Issues that could affect the result should be addressed fully rather than deferred in expectation of another opportunity.
That is a strategic implication of the decision, not a different standard of care created by the court.
The bias issue was not decided on appeal
The Court of Appeal did not adjudicate the remaining bias issue because it would not change the disposition.
That procedural outcome should not be presented as appellate approval or rejection of the underlying bias finding.
A court’s decision not to address an issue can reflect its lack of practical effect, rather than an assessment of its merits.
Seat selection includes court-review consequences
Parties choosing an arbitral seat should understand the relevant court framework alongside the tribunal rules.
Counsel should explain which matters can be reviewed, how that review proceeds and what appeal restrictions may apply. Those features can become consequential long after the arbitration clause is signed.
The decision reinforces a familiar principle with immediate practical effect: finality depends on the governing legislation, not the terminology a party prefers.
The appeal route comes from the statute - not the heading on the award.
