Self‑represented applicants sought mandamus with certiorari in aid compelling a justice of the peace to issue process on several private informations alleging child abduction, perjury, conspiracy, and accessory offences against a Children’s Aid Society worker, school principal, and other officials.
The justice of the peace had refused to issue process following a pre‑enquête hearing.
The court held that mandamus is available only where jurisdictional error is established, such as a failure to exercise jurisdiction or breach of natural justice.
The applicants were not denied a fair hearing and the justice considered the materials before him.
Even if some evidence arguably supported a perjury allegation, the proposed prosecution was frivolous, vexatious, and an abuse of process.
