Recently, in order to promote learning and making good use of the third batch of guiding cases of discipline enforcement and law enforcement of the Central Discipline Inspection Commission and the State Supervision Commission, all personnel of the case trial Office of the Hubei Provincial Discipline Inspection Commission and the supervision commission went to Huangshi City to hold a seminar on "three cascades" with relevant personnel of the case trial departments of the municipal and county discipline inspection commissions and the supervision commission. At the meeting, the participants conducted interactive exchanges and answered questions and doubts around the problems in the grass-roots accurate accountability, fault tolerance and correction, and discipline enforcement. The atmosphere was very warm. "The 'three cascade learning' has provided a good platform for grassroots discipline inspection and supervision cadres to learn and make good use of guiding cases. Through joint learning, discussion and exchange, our ability to accurately grasp discipline enforcement standards and apply policies and strategies has been further improved." Liu Youping, director of the case trial Office of the Hubei Provincial Discipline Inspection Commission and the Supervision Commission, said. In the trial practice, the situations of violations of discipline and law vary greatly. The means and forms of violations of discipline and law are invisible and varied. It is difficult for the relevant regulations and rules to cover all the problems and phenomena in detail. When encountering specific cases, there are often situations such as being unable to find, dare not use, and cannot use. In order to provide accurate and effective guidance to the lower level, from August 2021 to now, the Central Discipline Inspection Commission and the State Supervision Commission have issued three batches of guiding cases for Discipline enforcement and law enforcement. For the issued guiding cases, the discipline inspection and supervision organs at all levels conscientiously organized the discipline inspection and supervision cadres to carry out study, exchange and discussion through personal self-study, centralized discussion, telephone answering, case submission and other forms, deepen the application of case study results, promote the discipline inspection and supervision cadres to grasp the standards of discipline and law, and improve the level of accurate discipline enforcement ability. "In the guiding case, 'Wu's illegal apportionment case' indicates that such behavior has increased the burden of the masses and should be identified as illegal apportionment, which is a violation of mass discipline. In practice, we also need to accurately identify the nature of the problem according to whether the 'donation' is targeted at individuals or the majority of people, and whether the public officials receiving the 'donation' have 'special' profit-making matters for the donors." On July 4, the case trial Office of the supervision commission of Henan Provincial Discipline Inspection Commission organized all cadres to conduct in-depth study on the specific points in the guiding cases. The third batch of guiding cases focused on issues such as "eating official letters" in official receptions, "indiscriminate apportionment" that harms the interests of the masses, and the identification of the nature of opposing organizational review, and doing a good job in fault tolerance and responsibility reduction. Through vivid cases, the discipline explanation and reasoning provided clear guidance for Discipline Inspection and supervision organs at all levels to accurately and regularly carry out supervision, discipline enforcement and law enforcement. "In the process of investigating and handling corruption nest cases and string cases, the Discipline Inspection Commission and the supervision committee of the Inner Mongolia autonomous region often failed to truthfully explain problems, transfer hidden evidence, and other violations of discipline and law that did not cooperate with the review and investigation work. In particular, when discussing whether it was determined that it was a confrontation organization review or an organization letter that did not truthfully explain problems, there would be divergent opinions. The guiding case of the 'Xu confrontation organization review case' explained the problems thoroughly and accurately , it is very comprehensive, and everyone's doubts about this problem have been solved. " Said a relevant responsible person of the case trial Office of the Discipline Inspection Commission and the supervision commission of the Inner Mongolia Autonomous Region. In combination with the fact that Hainan Province is accelerating the construction of a free trade port with Chinese characteristics, Chi Xiaojuan, director of the case trial Office of the supervision commission of the Discipline Inspection Commission of Hainan Province, believes that the guiding cases issued by the Central Discipline Inspection Commission and the State Supervision Commission provide important guidance for the discipline inspection and supervision organs to standardize the work of fault tolerance and correction
