Public International Law - Montreal Convention. International Air Transport Association v. Canadian Transportation Agency
In International Air Transport Association v. Canadian Transportation Agency (Fed CA, 2022) the Federal Court of Appeal considered whether 'Ministerial Directions' under the Canada Transportation Act and related Regulations violated the Warsaw Convention, and it's successor the Montreal Convention, treaties addressing international aviation:
 The appellants challenge numerous provisions of the new Regulations on the basis that they exceed the Agency’s authority under the CTA. They claim that the regulations contravene Canada’s international obligations under the Convention for the Unification of Certain Rules Relating to International Carriage by Air, 12 October 1929, 137 L.N.T.S. 11 (the Warsaw Convention), its successor the Convention for the Unification of Certain Rules for International Carriage by Air, 28 May 1999, 2242 U.N.T.S. 309 (the Montreal Convention), and the Carriage by Air Act, R.S.C. 1985, c. C-26 (the CAA). They also allege that many of the Regulations’ provisions are ultra vires because they have impermissible extraterritorial effects, which violate fundamental notions of international law. Finally, the appellants challenge the Minister’s Direction on the basis that it exceeds the limitations imposed by its enabling statute.
