Social security benefits obtained via false documents must be returned in full if not granted otherwise.

The Supreme Court partially upheld the cassation appeal, remanding the case for a new ruling on costs while clarifying the scope of the appeal. The insured argued that interest on returned benefits was time-barred, but the court found the appeal did not cover the dismissal of the social security office's appeal. The court ruled that while the return of the principal benefit is governed by specific social security statutes, interest claims are subject to civil law limitation periods starting from the decision to return the benefit.
