Regulation 23 Witnesses
As soon as practicable after any list of proposed witnesses has been—
agreed under regulation 22(5); or
where there is no agreement under regulation 22(4), supplied under regulation 22(4),
the appropriate authority shall supply that list to the person conducting or chairing the misconduct proceedings.
The person conducting or chairing the misconduct proceedings shall—
consider the list or lists of proposed witnesses; and
subject to paragraph (3), determine which, if any, witnesses should attend the misconduct proceedings.
No witness shall give evidence at misconduct proceedings unless the person conducting or chairing those proceedings reasonably believes that it is necessary for the witness to do so in the interests of justice, in which case he shall—
where the witness is a police officer, cause that person to be ordered to attend the misconduct proceedings; and
in any other case, cause the witness to be given notice that his attendance is necessary and of the date, time and place of the proceedings.
