PDF Version: Alberta Court of Appeal Opines That Federal Carbon Pricing Legislation Unconstitutional
Decision Commented On: Reference re Greenhouse Gas Pollution Pricing Act, 2020 ABCA 74
Last month, the Alberta Court of Appeal released its decision in Reference re Greenhouse Gas Pollution Pricing Act, 2020 ABCA 74, Alberta’s challenge to the constitutionality of the federal government’s Greenhouse Gas Pollution Pricing Act, SC 2018, c 12 (GGPPA). Writing for a majority of three judges, Chief Justice Catherine Fraser concluded that the GGPPAcould not be upheld on the basis of Parliament’s residual power over matters of “peace, order, and good government” (POGG), nor any other potentially relevant federal head of power. Concurring in the result but not the analysis, Justice Wakeling also held that the GGPPA was unconstitutional. Justice Feehan, dissenting, would have upheld the law on the basis of POGG, and the “national concern” branch of that power in particular. The Alberta Court of Appeal’s decision thus stands in contrast to the earlier decisions of the Courts of Appeal of both Saskatchewan (Reference re Greenhouse Gas Pollution Pricing Act 2019 SKCA 40) (Saskatchewan Reference) and Ontario (Reference re Greenhouse Gas Pollution Pricing Act, 2019 ONCA 544) (Ontario Reference), where a majority of judges in each court upheld the law as a valid exercise of the national concern branch of the POGG power.
