Canadian legal standards and tests are generally referred to by the names of the appellants or complainants in the case (like Chee Chow David KOO) not the Gentleman or Lady Justice who presided (and generally prefer to just be called "Justice Last Name", rather than Old Man Justice, Young Woman Justice, Brunette Justice, Overweight Justice, Latino Justice, etc).
