The applicants sought mandamus compelling the SIU Director to lay a murder charge against a subject officer following a fatal police shooting, and also sought a declaration that the decision not to charge was tainted by anti-black racism.
The court held that, under s. 32 of the Special Investigations Unit Act, the Director's determination of whether reasonable grounds exist includes both subjective and objective components and permits consideration of all reliable information, including an obvious self-defence issue.
The Director did not err by considering self defence, and mandamus could not be used to force a particular charging result absent jurisdictional error, bad faith, discrimination, or failure to consider a highly relevant factor.
The court found no evidence that race motivated either the officer's conduct or the Director's decision.
Mandamus was also unavailable because a private prosecution under s. 504 of the Criminal Code provided an adequate alternative remedy.
