Executive Summary: Key Legal and Evidentiary Issues

• Judicial review centred on whether the Tribunal reasonably denied an extension of time to seek a re-hearing.
   
• Reasonableness was confirmed as the governing standard, consistent with Vavilov.
   
• Deference to the Tribunal's discretion under the Act and Rules shaped the entire analysis.
   
• Five Petersen factors were applied to assess prejudice, delay, intention, arguable case, and justice.
   
• Continuing intention to seek re-hearing was found lacking given the Applicant's deliberate pursuit of judicial review instead.
   
• No arguable case for re-hearing was established despite claims of unaddressed procedural and evidentiary errors.
   

Facts of the case

Paul Yuriy filed a psychological injury claim with the Workers' Safety and Compensation Commission (WSCC) in September 2020 following a workplace incident while employed by the City of Yellowknife. The WSCC denied the claim, but the Review Committee overturned that decision and found him eligible for compensation. The City appealed to the Workers' Compensation Appeals Tribunal, which held a documentary hearing on March 17, 2023; Yuriy had notice but did not participate. On June 24, 2023, the Tribunal reversed the Review Committee and denied the claim (the "Compensation Decision"). Rather than seeking a re-hearing within the six-month window set by Rule 57(2)(d) of the Appeals Tribunal Rules of Procedure, Yuriy filed an Originating Notice for judicial review on July 27, 2023. The City successfully moved to strike that notice as premature, and the Court did so on March 8, 2024 — by which point the re-hearing deadline had lapsed. Yuriy then applied to the Tribunal on May 6, 2024 for an extension of time and leave to re-hear; the Tribunal denied both on August 27, 2024 (the "Re-Hearing Decision"). Yuriy filed a fresh Originating Notice on September 25, 2024, seeking review of both decisions. At a pre-hearing conference, the Court limited the scope of review to the Re-Hearing Decision alone.

Policy and legislative provisions at issue

The case turned on provisions of the Workers' Compensation Act and its accompanying Rules. Section 132 of the Act gives the Tribunal discretion to re-hear an appeal, while Rule 57 permits a party to request that discretion be exercised, generally within six months absent new evidence. Rule 53(1) allows a party to request an extension of time, and Rule 53(4) confirms the Tribunal's power to adjourn proceedings or extend deadlines. Notably, the Act and Rules impose no statutory conditions or mandatory considerations governing this discretion. A privative clause in section 133 further restricts judicial review of Tribunal decisions to two narrow grounds: denial of natural justice and excess of jurisdiction. Rule 43 was also relevant, as it deems a party who does not participate in a hearing to have waived their right to do so.

Reasoning and analysis

Justice Taylor applied the reasonableness standard from Vavilov, emphasizing that significant deference was owed to the Tribunal. Framing her analysis around the five-factor test from Workers' Safety and Compensation Commission v Petersen, she addressed prejudice, continuing intention, explanation for delay, arguable case, and the justice of the case. On prejudice, she found it reasonable for the Tribunal to conclude the City would suffer some prejudice — increased legal costs and managerial uncertainty — even though not "significant." Regarding continuing intention, she agreed with the Tribunal that Yuriy's deliberate choice to pursue judicial review rather than a re-hearing, despite being warned his remedies were unexhausted, undermined any claim of continuing intention to seek re-hearing; she cited Petersen and Hughes v GN for the principle that pursuing one remedial avenue does not demonstrate intention to pursue another. On delay, she found Yuriy's explanations — reliance on the judicial review process and later, new counsel's need for preparation time — insufficient, particularly since he had legal representation and clear notice of the re-hearing deadline throughout. Turning to arguable case, she rejected arguments concerning the Tribunal's denial of a further extension for submissions on an unpublished decision, its treatment of certain factual findings, and its interpretation of WSCC policy; while she agreed the Tribunal's reasoning on one point (the interpretation of "traumatic" under WSCC policy) was inadequately explained, she held this did not render the decision as a whole unreasonable, citing Vavilov's guidance that decision-makers need not address every argument raised. Finally, on the justice of the case, she found the Tribunal reasonably prioritized finality and certainty, and that obiter comments from the earlier judicial review judge suggesting an extension should be granted did not bind the Tribunal's independent exercise of discretion.
