Supreme Court dismisses appeal for failure to cite legal grounds, even with later submission of a supplementary brief.

The Supreme Court rejected the appellant's cassation appeal against a labor dispute judgment regarding wrongful termination. The appellant argued for a material law violation and procedural error but failed to explicitly cite the specific legal provisions violated in the initial filing. The court held that a supplementary letter submitted within the deadline could not cure this defect because it was not formally filed by the appointed attorney, rendering the appeal inadmissible.
