The employer subsequently questioned the conclusion of the agreement, stating that the rules for delivery under the Labour Code were not observed. The Supreme Court stated that the Labour Code lacks a comprehensive regulation of legal acts, and therefore the rules in the Civil Code will apply to concluding agreements. This means that even if the rules for delivery in employment relations are not observed, bilateral legal acts may arise in the manner described above, which is in accordance with the Civil Code.

The problem, however, is that the Supreme Court (with regard to the appeal argumentation) did not address the question of the validity of such a legal act in this case.
