修改后的刑事诉讼法对证人在何种情况要出庭做出了规定,并对证人不履行出庭义务规定了强制出庭制度,同时还规定了证人强制出庭作证的豁免。另外还对证人出庭的后续保障即证人作证补偿及证人保护进行了规定。但对证人不出庭或者出庭不作证没有进行规定。 The amended Criminal Procedure Law provides for the circumstances under which witnesses appear to attend court and provides for mandatory court appearances on the failure of witnesses to fulfill their obligations of attendance. At the same time, it also provides for the exemption of witnesses from compelling to testify in court. In addition, follow-up support for the appearance of witnesses is provided for witness compensation and witness protection. However, there is no provision for the witness not to appear in court or not to appear in court.
