Court of Appeal, February 26, 2026, request for discretionary review, UPC_CoA_34/2026

3 min Reading time

Key takeaways

The appellant argued that the CFI’s reference to R. 354.4 RoP in the impugned order created the impression that leave to appeal had already been granted, analogous to Total v. Texas Instruments (CoA_651/2024). The Court of Appeal rejected this, holding that R. 354.4 RoP clearly refers to R. 220.2 RoP.

An attorney-represented party is expected to recognize from the applicable rules and Court of Appeal case law that a request for leave to appeal is required. Ambiguity in the CFI’s guidance does not excuse failure to comply with the procedural requirements.

Discretionary review by the Court of Appeal is only available where the CFI has actually denied a request for leave to appeal. Where the appellant failed to file a timely request for leave within the 15-day period of R. 220.2 RoP, the precondition for discretionary review is not met and the request is inadmissible.

The Court left open what applies where the CFI fails to decide within the 15-day time limit despite a timely request for leave to appeal (citing Suinno v. Microsoft, CoA, 9 October 2024, UPC_CoA-586/2024).

The appellant’s auxiliary request that the Court of Appeal itself grant leave to appeal was dismissed as inadmissible. Art. 73(2)(b) UPCA empowers “the Court” – meaning the court that issued the impugned order – to grant leave. The Court of Appeal’s role is limited to discretionary review under R. 220.3 RoP, if admissibility conditions are met.
