Failure to state termination reason in the initial notice violates Art. 30 § 4 KP; later supplementation does not cure the defect.

The Supreme Court dismissed the cassation appeal against a labor court ruling awarding damages for an unlawful termination. The employer failed to cite the reason for termination in the initial notice sent to the employee, violating Art. 30 § 4 of the Labor Code, but later provided the reason in a supplementary letter. The court held that this subsequent supplementation could not validate the initial procedural defect because the statutory requirement to state the reason is protective and must be met at the moment of delivery to allow the employee to timely exercise their right to appeal.
