四个法域均有特别法律规定保护遭受威胁和身处弱势的证人。波斯尼亚和黑塞哥维那一项新的证人保护计划法律规定，须在刑事诉讼前后及 过程中有效地保护证人，确保证人能在刑事诉讼中自由公开地作证。然而，向波斯尼亚和黑塞哥维那法院呈交证人证词的做法受到诸多约束，这严重限制了 法律适用。此外，该法也仅限于特定犯罪。 目前，在国家一级作证的证人得到了国家调查保护局的保护。在实体一级，证人保护由执法机关负责。
There is a special law on the protection of witnesses under threat and of vulnerable witnesses in all four jurisdictions. A new law on the witness protection programme in Bosnia and Herzegovina provides for efficient protection of witnesses before, during and after criminal proceedings, in order to enable the witnesses to testify freely and openly in criminal proceedings. However, the restrictions on bringing witnesses testimony before the Court of Bosnia and Herzegovina seriously limit the application of the law. Moreover, the scope of the law is limited to certain crimes. Currently, witnesses testifying at the State level are protected by the State Investigation and Protection Agency. At entity level, witness protection is the responsibility of the law enforcement authorities.
