The two regulations supporting each other, the code adhere to a positive advocate, focusing on morality is of Party members and Party leading cadres can see, enough to get a high standard。 rule around the party discipline, disciplinary ruler requirements, listed as negative list, focusing on vertical gauge, draw the party organizations and Party members do not touch the bottom line . Here, the main from four square face two party rules of interpretation: the first part introduces two party Revised regulations the necessity and the revision process。 the second part is the interpretation of the two fundamental principles of the revision of laws and regulations in the party。 the third part introduces two party regulations modified the main changes and needs to grasp several key problems。 the fourth part on how to grasp the implementation of the two regulations of the party. code and Regulations revised the necessity and revised history of the CPC Central Committee the amendment to the Chinese Communist Party members and leading cadres honest politics several guidelines and Chinese Communist Party discipline and Punishment Regulations column 1 by 2015 to strengthen party laws and regulations focus. Two party regulations revision work lasted a Years, pooling the wisdom of the whole party, ideological consensus, draw historical experience, respect for the wisdom of our predecessors, which reflects the unity of inheritance and innovation。 follow the correct direction, grasp the limited goals, adhere to the party39。s leadership, to solve the masses of the people reflect a focus on the problem. The new revision of the code and rule , reflects the party39。s 18 and the eighth session of the third, the spirit of the fourth plenary session, reflecting the experience of studying and implementing the General Secretary Xi Jinping series of important speech, reflects the party39。s eighteen years prehensive strictly practice. (a) revised two regulations of the party need of the ICAC guidelines in in 1997 Leaders as members of the Communist Party of China clean politics certain criteria (Trial) based on revised, the promulgation and implementation of January 2010, to strengthen the construction of the contingent of leading cadres play an important role. But with the party to manage the party strictly administering the deepening, has not been able to fully meet the actual needs. Content is too plicated, eight prohibition, 52 are not allowed to hard to remember, and also difficult to put into practice。 the second is concisely positive advocated by the lack of prohibited provisions excessive, no autonomy requirements。 the third is banned terms and discipline law, both with the party discipline, disciplinary regulations repeat and Criminal law and other laws and regulations repeat。 the fourth is to clean the theme is not prominent, not for the existing problems, and is narrow, only needle of countylevel leading cadres above. rule is in 1997 Chinese Communist Party disciplinary cases (Trial) based on revision, in Dece
