Appeal misdirected to wrong court after proper notice does not justify missing statutory deadline under Polish Civil Procedure Code.

The Supreme Court dismissed the cassation appeal filed by a worker against a decision denying his request to restore the appeal deadline. The lower courts found that although the applicant's mother mailed the appeal to the wrong court, the applicant had been properly informed of the correct procedure and failed to exercise due diligence. The Supreme Court held that this error constituted negligence rather than a procedural violation warranting relief, thus upholding the dismissal of the appeal.
