Supreme Court Rules 2000

Any party in any proceeding, by subpoena to give evidence or subpoena to produce documents, may require the attendance of any witness before the examiner in the same manner as the witness would be required to attend and be examined at a trial.

A person who makes an affidavit intended to be used in the proceeding is bound on being served with such a subpoena to attend before the examiner for cross-examination.
