Quick Summary of Hostile Witness


A hostile witness (also known as an adverse witness or unfavourable witness) is someone whose testimony is considered unfavourable to the party who called them to testify. A hostile witness may be asked leading questions and may be cross-examined by the party who called them to the stand after the questioning attorney asks the judge to declare the witness as hostile. After this declaration, the attorney will have more leeway to question the witness and possibly produce testimony which is better for their client.

Having a witness declared as hostile is done much less frequently in real life than in television crime dramas. Prior to the trial each attorney has prepped their witness and questioned them enough to understand what their testimony is likely to cover, although occasionally there is testimony provided by a witness that is unexpected or is less supportive than originally thought.




What is the dictionary definition of Hostile Witness?

Dictionary Definition


n. technically an “adverse witness” in a trial who is found by the judge to be hostile (adverse) to the position of the party whose attorney is questioning the witness, even though the attorney called the witness to testify on behalf of his/her client. When the attorney calling the witness finds that the answers are contrary to the legal position of his/her client or the witness becomes openly antagonistic, the attorney may request the judge to declare the witness to be “hostile” or “adverse.” If the judge declares the witness to be hostile (i.e. adverse), the attorney may ask “leading” questions which suggest answers or are challenging to the testimony just as on cross-examination of a witness who has testified for the opposition.


Full Definition of Hostile Witness


A witness is ‘hostile’ if his oral testimony is harmful to the side calling him, and in conflict with the expectations of that side.

Suppose, for example, that a witness makes a statement to the police that supports a particular view of the facts surrounding an offence (see previous statement), and is later called as a witness to be examined on that view. If he then offers evidence that is in outright disagreement with his original statement, the party calling him may ask the judge to grant leave to treat him as a hostile witness. If leave is granted, the witness may be examined on his previous statement, and he may be asked leading questions (R v Thompson1976).

Until recently it was strictly the case that evidence of previous statements, whether made by a hostile witness or not, were not admissible to show the truth of their contents, but only to attack the credibility of the witness’s testimony. In practice, particularly in jury trials, it was impossible to expunge from the memory the contents of the previous statement, and it would be almost impossible not to take it into account. This situation is tidied up by s.119 of the CJA 2003, which allows for previous statements to be admitted to prove the truth of the matters stated.

Until recently there was some uncertainty whether a witness who was not compellable (see compellable witness) could be declared hostile. After all, if the witness cannot be compelled to testify at all, surely he or she cannot be compelled to testify in line with the expectations of the person calling that witness?

However, in R v Pitt 1982, it was held that once a non-compellable witness takes the oath, that witness must give testimony just like any other witness, and so can be declared hostile.

However, the Court of Appeal suggested that the situation should never arise – the judge ought to ensure that a non-compellable witness is fully aware of his or her right not to testify before taking the oath.
