Article 450. Grounds for amendment and termination of the contract.
1. Change and termination of the contract are possible by agreement of the parties, unless otherwise provided by this Code, other laws or the contract. 2. At the request of one of the parties, the contract may be changed or terminated by a court decision only: 1) in the event of a material breach of the contract by the other party; 2) in other cases stipulated by this Code, other laws or a contract. A violation of a contract by one of the parties is recognized as significant, which entails for the other party such damage that it is largely deprived of what it was entitled to expect when concluding the contract. 3. In the event of a unilateral refusal to perform the contract in full or in part, when such a refusal is permitted by law or by agreement of the parties, the contract shall be deemed terminated or modified accordingly.
