Polish Supreme Court dismisses cassation when a party fails to submit evidence and later claims procedural violation.

The Polish Supreme Court dismissed the cassation appeal filed by Jadwiga B. against a decision denying her rural disability pension. The applicant argued that the lower court violated procedural rules by relying on expert opinions without allowing her to present new evidence. The court ruled that because the applicant refused to actively participate in proceedings and did not submit any evidence, she cannot later claim a procedural violation in the cassation stage.
