Polish Supreme Court dismisses appeal for retrial, ruling appellate court erred by deciding on a closed session instead of a public hearing.

The Polish Supreme Court dismissed the cassation appeal against an appellate court's decision to reject a motion for retrial. The appellant argued the lower court improperly decided the case on a closed session rather than a public hearing, and failed to address a new ground for retrial raised in the written petition. The Supreme Court held that the appellate court erred by ruling on the admissibility and merit of the retrial motion during a closed session, violating the principle of public hearings, and thus remanded the case for a proper hearing.
