Saskatchewan v. Canada re Greenhouse Gas Pollution Pricing Act; Bill C-74, Part 5
Jurisdiction: Court of Appeal for Saskatchewan, Canada
Principle law(s): Greenhouse Gas Pollution Pricing Act
Side A: Saskatchewan (Government)
Side B: Canada (Government)
On May 3, 2019, the Court of Appeal for Saskatchewan ruled that the (GGPPA) is not unconstitutional in whole or in part by a 3-2 majority. The court rejected Canada's broader argument that Parliament has jurisdiction over "the cumulative dimensions of GHG emissions" under the national concern branch of its "Peace, Order, and good Government" [POGG] power. The court found this approach would exceed the constitutional authority of Parliament and intrude too far into areas of Provincial authority and limit Provincial efforts to deal with GHG emissions. However, the Court did rule that Parliament has more narrow authority under the POGG to establish "minimum national standards of price stringency for GHG emissions" because this authority "has the singleness, distinctiveness and indivisibility required by the law." Accordingly, the court ruled that the GGPPA is constitutionally valid under this more narrow POGG authority.
The Attorney General for Saskatchewan has appealed the decision. Related documents will be posted and summarized when available. The provinces of Manitoba and Ontario have also challenged the constitutionality of the GGPPA and those cases are pending. The Paris Agreement was among the laws discussed in the preamble of the GGPPA in regard to the need for a carbon pricing mechanism.
