Bank of Montreal v Marcotte
Bank of Montreal v Marcotte,  2014 SCC 55 is a ruling of the Supreme Court of Canada. Together with Amex Bank of Canada v. Adams,  2014 SCC 56 and Marcotte v. Fédération des caisses Desjardins du Québec,  2014 SCC 57 (collectively known as the "Marcotte trilogy"), it represents a further development in Canadian constitutional jurisprudence on the doctrines of interjurisdictional immunity and paramountcy, together with significant clarifications on the law concerning class actions in the Province of Quebec, which is similar to that in operation in the common law provinces.
