刑事证人是指犯罪嫌疑人、被告人和被害人之外的、与案件没有直接利害关系的、向公安、司法机关陈述自己耳闻目睹的案件有关事实的个人和单位。作证不应当定位为证人的义务 ,而应当定位为证人的权利。《刑事诉讼法》第 4 8条第 1款的规定存在重大缺陷 ,应将其修改为 :除法律另有规定外 ,所有耳闻目睹案件有关事实的人 (单位 )都有作证的资格。 Criminal witness refers to individuals and units other than suspects, defendants and victims who have no direct interest in the case and state to the public security and judicial organs about the facts of the cases they have heard or heard. Testification should not be a witness's obligation, but rather a witness's right. Article 48, paragraph 1, of the Code of Criminal Procedure has major defects. It should be amended to read as follows: All persons (units) that have witnessed the facts concerning the case are eligible to testify unless the law otherwise provides.
