Justices of the Supreme Court of Canada have the option of releasing reasons for a unanimous decision anonymously by simply attributing the judgment to "The Court".
The practice began around 1979 by Chief Justice Bora Laskin, borrowing from the US Supreme Court practice of anonymizing certain unanimous decisions.
[2] It has been suggested that the practice has been used to give greater authority to the decision by having the entire court speak as a single voice.
[3] Peter McCormick, a professor of political science at the University of Lethbridge who studies Canada's appellate courts, calls these "per coram decisions", but his terminology is not in general use.
McCormick states that there were 9 reported per coram decisions prior to Laskin's term as Chief Justice of Canada, 15 reported per coram decisions under Laskin's chief justiceship, and 51 reported per coram decisions under Brian Dickson's chief justiceship.
