Cassation appeal dismissed; employee cannot challenge termination effects without timely appeal or valid claim.

The Supreme Court dismissed the cassation appeal filed by a teacher against her employer's termination of her employment contract. The court found that the employee failed to timely appeal the dismissal, which legally terminated the employment relationship and barred her from challenging its effects. Furthermore, the court ruled that the employee lacked a legal interest in establishing the existence of a separate appointment-based relationship after the contract had definitively ended.
