Failure to specify the value of the subject matter of appeal in a social security increase case leads to dismissal of the cassation appeal.

The Supreme Court dismissed the cassation appeal filed by Marian W. against a decision regarding the recalculation of his disability pension. The appellant argued that the lower court incorrectly assumed he was properly summoned to complete the appeal, claiming the summons lacked identifying details. The court ruled that because the dispute concerned an increase in social security benefits, the appellant was legally obligated to specify the value of the subject matter of the appeal, a requirement independent of its relevance to admissibility.
