回避制度是保证刑事诉讼活动能够客观、公正的重要措施,其核心问题是回避理由,即何种情形下司法人员须回避。从理论上讲,回避理由在原则上很明确,就是凡可能影响案件公正处理的司法人员都得回避。但因为这一原则在司法实践中不便操作,我国刑事诉讼法采取列举的方式予以具体化,? The avoidance system is an important measure to ensure that criminal proceedings can be objective and fair. The core issue is to evade the reasons, that is, under any circumstances, judicial personnel should evade. In theory, the grounds for avoidance are clear in principle, that is, judicial personnel who may affect the fair handling of cases must be circumvented. However, because this principle is inconvenient to operate in judicial practice, China’s criminal procedure law should be enacted by enumeration.
