刑事回避对于保障司法公正和当事人权益、提高司法公信力具有重要的制度价值。但现行制度存在回避事由狭窄、举证责任不明确、单位回避缺失等问题,建议从扩大回避事由,明确举证责任,增设单位回避和建立公安司法人员公示制度等方面进行完善。 Criminal avoidance has an important institutional value for safeguarding judicial fairness and the rights and interests of parties, and enhancing the credibility of the judiciary. However, the current system has some problems such as narrow evasion, unclear burden of proof and lack of avoidance of units. Suggestions are made to improve such aspects as expanding the evading cause, clarifying the burden of proof, setting up units to evade and establishing a public announcement system for public security officers.
