Certiorari is granted either on two grounds: error of law on face of the record or jurisdictional error. Certiorari can only be granted if it is "possible to identify a decision which has a discernible or apparent legal effect upon rights". Certiorari may also be granted to correct errors of law that can be established on the face of the record. "The record" includes documents that initiate proceedings, pleadings of the parties, ultimate order in the proceedings etc. However, it does not include transcripts of proceedings, exhibits, or the reasons given for decisions, unless the tribunal chooses to incorporate reasons.
