By Order in Council 112/2019, the Lieutenant Governor in Council referred the following question to the Court of Appeal of Alberta pursuant to s. 26 of the Judicature Act, R.S.A. 2000, c. J-2:
Whether the Greenhouse Gas Pollution Pricing Act is unconstitutional in whole or in part.
A majority of the Court of Appeal for Alberta found that Parts 1 and 2 of the Act are unconstitutional in their entirety and declined to express any opinion on Parts 3 and 4. In concurring reasons, Wakeling J.A. came to the same conclusions as the majority, but for different reasons. In a dissenting opinion, Feehan J.A. would have found the Act constitutional.
