The new revision of the code and rule , reflects the party39。 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。s eighteen, ten eight plenary, the spirit of the Fourth Plenary Session of the Eleventh Central Committee and General Secretary Xi Jinping important instructions on the revised low political criterion and Regulations , highlighting the ruling party characteristics, serious discipline, the discipline quite in front of the law, based on the current, a longterm, advance as a whole, with Bu Xiuding independent rule and rule . Main principle is: first, adhere to the party constitution to follow. The constitution about discipline and selfdiscipline required specific, awaken the party constitution of party passes party consciousness, maintaining the authority of the constitution. General Secretary Xi Jinping pointed out that no rules, no side round. Party constitution is the fundamental law, the party must follow the general rules. In early 2015 held the eighth session of the Central Commission for Discipline Inspection Fifth Plenary Session of the 16th Central Committee, Xi Jinping again pointed out that constitution is the party must follow the general rules, but also the general rules. the revision of the code and rule is Method in adhere to the regulations established for the purpose of bining rule of virtue is to adhere to the party constitution as a fundamental to follow, the constitution authority set up, wake up the party constitution and party rules the sense of discipline, the party constitution about discipline and selfdiscipline specific requirements. 4 second is to adhere to in accordance with the regulations governing the party and the party. The Party of rule of virtue de, mainly refers to the party39。s advanced nature and purity, to reflect the revised standards requirements. Members of selfdiscipline norms around the party members how to correctly treat and deal with the public and private, cheap and rot thrifty and extravagance bitter music, put forward the four norms. Party leader cadre clean fingered selfdiscipline norms for the leadership of the party members and cadres of the vital few, around the clean politics, from civil servant of the color, the exercise of power, moral integrity, a good family tradition and other aspects of the leadership of the party members and cadres of the four norms norm norm. The Party member39。s leadership and the party39。s eighteen years implement the spirit of the central provisions of the eight, against the requirements of the four winds and transformation for disciplinary provisions, reflecting the style construction is always on the road, not a gust of wind. In the fight against corruption out of new problems, increase the trading rights, the use of authority relatives profit and other disciplinary terms. Prominent discipline of the masses, the new against the interests of the masses and ignore the demands of the masses and other disciplinary terms and make provisions of the disposition and the destruction of the party39。s image, the damage to the party, the state and the people39。s court shall make a conviction and exempted from criminal punishment shall be given within the party is removed from his post, probation or expelled from the party. Party members and crime, sheets were fined in accordance with For acts
