Cassation appeal dismissed; salary determination for customs officer not an administrative act subject to administrative court jurisdiction.

The Supreme Court dismissed the cassation appeal filed by a customs officer against a labor court judgment awarding him back pay. The lower courts correctly identified that setting a customs officer's salary is a service relationship matter governed by the Customs Service Act, not an administrative act requiring administrative court review. The appeal failed because the plaintiff relied solely on procedural errors without citing specific material law provisions that would substantiate his claim.
