Rules of evidence govern whether, when, how, and for what purpose, proof of a legal case may be placed before a trier of fact for consideration. Prevailing in court requires a good understanding of the rules of evidence in the given venue. The rules vary depending upon whether the venue is a criminal court, civil court or family court, and they vary by jurisdiction. One reason to have a lawyer, among others, is that he or she should be familiar with the rules of evidence. If one were allowed simply to tell the court what one knew to be the truth, and how one knew it, one might prevail. However, the rules of evidence may prohibit one from presenting one's story just as one likes. Some important rules involve relevance, privilege, witnesses, opinions, expert testimony, hearsay, authenticity, identification and rules of physical evidence. ==History== The rules of evidence were developed over several centuries and are based upon the rules from Anglo-American common law brought to the New World by early settlers. Their purpose is to be fair to both parties, disallowing the raising of allegations without a basis in provable fact. They are sometimes criticized as a legal technicality, but are an important part of the system for achieving a just result. Perhaps the most important of the rules of evidence is that, in general, hearsay testimony is inadmissible (although there are many exceptions to this rule). In the United Kingdom, the Civil Evidence Act 1995, section 1, specifically allows for admission of 'hearsay' evidence; legislation also allows for 'hearsay' evidence to be used in criminal proceedings, whichg makes it impossible for the accuser to induce friends or family to give false evidence in support of their accusations because, normally, it would be rejected by the presiding authority or judge. There are several examples where presiding authorities are not bound by the rules of evidence. These include the military tribunals in the United States and tribunals used in Australia to try health professionals. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「rules of evidence」の詳細全文を読む スポンサード リンク
