A court grants permission by issuing a writ known as a warrant.

The court grants permission to between 40 and 75 litigants each year to appeal decisions rendered by provincial, territorial and federal appellate courts.

However, the application for a declaration can not be made unless the court grants leave for the prerogative orders to be applied for.

If the plaintiff brings only equitable claims but the defendant asserts counterclaims of law, the court grants a jury trial.

When the court grants review, and in cases involving mandatory review, the parties are notified of the briefing requirements under the court's rules.
