Along with the development of the situation, which many provisions have been unable to fully meet the prehensive strictly administering the practice needs. One is Ji law, more than half of the provisions and criminal law and other countries laws and regulations Repetition。s ideals and beliefs, excellent traditional style. The revised the code closely linked to the selfdiscipline, insisting on the positive initiative, for all members, highlight the vital few, emphasized selfdiscipline, focusing on the morality, and the majority of Party members and the ideological and moral standards. The revised Ji method separately, Ji, Ji Yan to Method, as a negative list, emphasizing the heteronomy, focusing on vertical gauge. Is this one high and one low, a positive reaction, the strict party discipline and practice results transformation for the integration of the whole party to observe moral and discipline requirements, for the majority of Party members and cadres provides benchmarking and ruler. Third, insist on to. In view of the problems existing in the party at the present stage, the main problems of Party members and cadres in the aspect of selfdiscipline and abide by the discipline to make clearly defined, especially the party39。s selfdiscipline norms and party members and leading cadre clean fingered selfdiscipline norms, a total of eight, collectively referred to as the eight. Four must and eight of the content from the party constitution and Party39。s basic theory, basic line, basic program and basic experience, the basic requirement of behavior made prescribed punishment, increase the cliques, against the organization such as violation of the provisions, to ensure that the central government decrees and the Party of centralized and unified. 3, adhere to strict discipline in the law and discipline In front, Ji separated. Revised Regulations adhere to the problem oriented, do Ji separated. Any national law existing content, will not repeat the provisions, the total removal of 79 and criminal law, repeat the content of the public security management punishment law, and other laws and regulations. In the general reiterated that party organizations and Party members must conscientiously accept the party39。s close ties with the masses. Discipline to protect the party39。s interests, we should depend on the situation Seriousness given disciplinary action. The loss of Party members, seriously damaging the party39。 the principal Ordinance amended the provisions of the preceding paragraph. This is the new content, in order to achieve Ji method effective convergence. Five is the thirty third article 10 of the provisions, the Party member due to an intentional crime is sentenced to criminal law (including probation) sheets or additional deprivation of political rights。s decision to get quickly and effectively implementing. The Party Central Committee formulated the major principles and policies, through different channels and ways, fully listen to the party organizations and Party members of the opinions and suggestions, but 12 is some people face to face not to say back blather will not say, after the meeting said, Taiwan does not say, and nonsense , in fact, not only disrupt the people thought, some causing serious consequences, the damage to the Party of the centralized and unified, hinder the central policy implementation, but also a serious violation of the democratic system of principles. There is no doubt that shall, in accordance with the Regulations 4 Specified in Article 6 to give the appropriate punishment. For did not cause serious c
