【Abstract】 The establishment and going into effect of the contract are two different concepts. The establishment of a contract does not necessarily mean it shall go into effect. If the contract does not confirm to the valid essential elements stipulated by the contract law, it shall be void and have no legal binding force. Parties shall not perform the invalid contract for its violation of the contract law; otherwise they shall bear the responsibility for breach of the contract law.

These provisions shall be applied to handling cases.更多还原
