Executive Summary: Key Legal and Evidentiary Issues

• The applicant challenged a Licence Appeal Tribunal settlement, arguing he lacked capacity to enter into it.

• Medical evidence submitted post-settlement was central to the capacity dispute and procedural fairness arguments.

• The LAT ruled it had no jurisdiction to set aside the agreement, which the Divisional Court later upheld.

• The Superior Court analyzed whether the LAT made a reviewable error in rejecting the capacity-based challenge.

• The court affirmed the LAT’s jurisdictional stance and emphasized the finality of validly executed settlements.

• The appeal was dismissed, confirming the binding nature of LAT settlements unless proven invalid through proper legal channels.

Background and procedural history

In 2021, Gerard Sistermans was involved in a motor vehicle accident and later resolved his entitlement to no-fault accident benefits through a full and final settlement with CAA Insurance Company. The settlement was executed under the Statutory Accident Benefits Schedule (SABS), and it included a waiver of any future claims related to the accident. Mr. Sistermans, unrepresented at the time, later challenged the settlement before the Licence Appeal Tribunal (LAT), arguing he lacked capacity to understand or consent to the agreement.

He filed a request to rescind the settlement under Rule 19 of the LAT Rules. The LAT adjudicator dismissed the request on jurisdictional grounds, stating that the LAT lacked authority to invalidate a settlement agreement on the basis of mental incapacity. That decision was upheld on reconsideration. Mr. Sistermans then brought an appeal to the Divisional Court and, following that, this further appeal to the Superior Court of Justice.

Allegations of incapacity and evidence submitted

The central argument on appeal was that Mr. Sistermans suffered from diminished mental capacity at the time of settlement due to brain injuries sustained in the accident. In support, he submitted retrospective medical evidence suggesting cognitive impairment. He argued that the LAT erred in failing to consider this evidence or hold a hearing to evaluate the settlement’s validity.

The LAT, however, concluded that its role was limited to enforcing the terms of the SABS and that disputes concerning a party’s capacity to enter into a contract fall outside its statutory authority. It noted that parties seeking to overturn a settlement on such grounds must do so through the Superior Court, not through LAT proceedings. The Divisional Court endorsed this position, emphasizing the LAT’s limited remedial jurisdiction.

Superior Court’s reasoning on appeal

Justice Kristjanson of the Ontario Superior Court confirmed the findings below. She held that the LAT’s interpretation of its jurisdiction was reasonable and consistent with administrative law principles under Vavilov. The court reiterated that administrative tribunals are creatures of statute and cannot assume powers beyond what legislation expressly or implicitly provides. The LAT could not adjudicate claims of legal incapacity or set aside contracts on equitable grounds—matters reserved for the courts.

The judge also rejected the appellant’s argument that the tribunal breached procedural fairness by refusing to consider the capacity evidence. The tribunal’s decision to limit its analysis to its jurisdiction was within its discretion and properly executed under its enabling framework.

Conclusion and outcome

The appeal was dismissed. The court concluded that the LAT reasonably interpreted its jurisdiction and was correct in determining it lacked authority to set aside the settlement on capacity grounds. Justice Kristjanson reinforced that while parties with valid incapacity concerns may pursue remedies, such challenges must be brought in the appropriate forum—namely, the Superior Court, not before an administrative tribunal like the LAT. Costs were awarded to the respondent in the amount of $7,500.
