根据西班牙的证人保护法律（第 19/94 号法律），采取证人保护措施需要一项司 法判决；这些措施由内政部分派警察部队执行。法官可指令证人或鉴定人在不 披露其身份、视频保护或在登记法院而不是他们的住所情况下参与诉讼程序，并且警察可禁止对他们进行拍照或录像。进一步援助包括警察保护、使用新身 份或经济手段在不同地方开始新的生活。西班牙没有具体的机构证人保护方 案；在个案基础上决定采取何种措施。这些措施的最小持续时间是从法院诉讼 开始持续到必要长的时间。没有关于被保护证人人数的统计数据，也没有关于 在其中向证人提供了保护的犯罪类型以及关于采取何种措施使证人受到保护的 统计数据。
According to Spain’s witness protection law (Law 19/94), witness protection measures require a judicial decision; they are implemented by the Ministry of Interior, respectively the police forces. The judge can order that the witness or expert participate in the proceedings under reservation of their identity, under visual protection or under registration of the court instead of their residence, and that the police can inhibit that their photos or videos are taken. Further assistance includes police protection, new identities or economic means to initiate a new life at a different place. Spain does not have a specific institutional witness protection programme; the measures are decided upon on a case by case basis. The minimum duration of the measures is the time of the court proceedings, extending as long as necessary. No statistics are kept concerning the number of protected witnesses, neither with regard to the type of offences in which witness protection had to be provided, nor the measures by which witnesses were protected.
