For a long time, the company has taken the pre conference law learning system as an important starting point to strengthen the construction of the company's rule of law and create a strong atmosphere of rule of law, and gradually formed a set of institutionalized pre conference law learning system. On March 15, 2019, the company held the 2nd general manager office meeting. During the meeting, the Legal Advisory Center organized and studied the interpretation of the Supreme People's Court on the application of law in the trial of construction contract disputes, focusing on Article 1. When the construction contract of construction project has any circumstances, it shall be deemed invalid in accordance with item (5) of Article 52 of the contract law; Article 26 If the actual construction contractor brings a lawsuit against the subcontractor or illegal subcontractor as the defendant, the people's court shall accept it according to law. If the actual construction contractor claims rights with the employer as the defendant, the people's court may add the subcontractor or illegal subcontractor as the party to the case. The employer shall be liable to the actual constructor only within the scope of the unpaid project price. Through this study, all participants have a deeper understanding of the law, which is conducive to strengthening the awareness of legal risk prevention and improving the level of compliance.
