Obtaining a Mistrial in Alberta
In the recent case of , Roberts v Edmonton Northlands, 2022 ABQB 515 the court considered mistrials in Alberta.
The Court said at paragraph 7:
In R v Burke, 2002 SCC 55 at para 75, Justice Major directed trial judges deciding mistrial applications with the following test: “in declaring a mistrial, the trial judge therefore turns his or her mind to the question of whether a mistrial is needed to prevent a miscarriage of justice.”
 The following legal principles govern an application for a mistrial in both civil and criminal matters:
• A mistrial is a discretionary remedy and should be avoided if reasonable alternatives exist: Craggs v Stolz, 2004 ABCA 196 at para 4 and Homeniuk v Costain, 2008 ABQB 197 at para 3.
• Competent counsel is a component of a fair trial and counsel is presumed competent: R v GDB, 2000 SCC 22 at paras 25 and 27 [GDB].
• The onus to demonstrate the necessity of a mistrial rests on the party seeking the mistrial: GDB at para 27.
• Incompetence of counsel can amount to a miscarriage of justice; however, a nexus must exist between the incompetence and prejudice to client: R v Meer, 2015 ABCA 141 at para 43.
• A court should generally only opine on competence of counsel if it is apparent that prejudice has occurred: GDB at para 29.
• Evidence is required to support an application for a mistrial: R v Levin, 2012 ABQB 769 at para 57.
