Polish Supreme Court dismisses appeal and cassation due to untimely submission of case value without valid excuse.

The Polish Supreme Court dismissed both the appeal and cassation filed by a social insurance claimant against a labor court decision. The lower court rejected the cassation because the lawyer failed to submit the case value within the statutory deadline, and the subsequent request to extend the deadline was also denied. The Supreme Court upheld this ruling, finding that the claimant's inability to contact his lawyer did not constitute a valid reason for the delay.
