证人证言是刑事诉讼中运用最普遍、最复杂的证据种类之一,它有利于尽快查明案件事实,提高诉讼效率。长期以来,在司法实践中,询问证人困难、证人拒绝出庭等现象屡见不鲜。因此侦查机关、司法机关特别强调证人的作证义务,追求证人的出庭率,并且通过相关的法律制定、宣传教育等方式来加强公民履行作证义务的法律意识。但是在这一过程中,我们往往忽视了对证人合法权益的有效保障。证人的拒证权就是其中十分重要的一项。 Witness testimony is one of the most common and complex types of evidence used in criminal proceedings. It is good for ascertaining the facts of a case and improving the efficiency of litigation as soon as possible. For a long time, in the judicial practice, it is not uncommon to ask witnesses for difficulty or to refuse to appear before a court. Therefore, the investigating authorities and the judiciary especially emphasize the witness’s obligation to testify, pursue the witness’s attendance rate, and strengthen the legal awareness of citizens in performing their duty of giving evidence through relevant laws, publicity and education. However, in this process, we often neglect the effective protection of the legitimate rights and interests of witnesses. The right of witness to testify is one of the most important ones.
