Opinion of the Court
McLachlin, writing for the majority, held that the law was a valid Act of the Parliament of Canada.
Her analysis began by examining the pith and substance of the law. She divided it into two steps. First, the court must determine the "essential character of the law", and second, whether "that character relates to an enumerated head of power" under the Constitution Act, 1867.
On the first step she consolidates all of the principles from the previous case law on the matter.
- What is the true meaning or dominant feature of the impugned legislation? This is resolved by looking at the purpose and the legal effect of the regulation or law... The purpose refers to what the legislature wanted to accomplish. ... The legal effect refers to how the law will affect rights and liabilities, and is also helpful in illuminating the core meaning of the law. The effects can also reveal whether a law is "colourable", i.e. does the law in form appear to address something within the legislature's jurisdiction, but in substance deal with a matter outside that jurisdiction. [3]
McLachlin says that the court must look at the wording of the Act as well as the circumstances that it was enacted.
On the facts of the case the purpose of the regulation was
- to regulate the seal fishery by eliminating the commercial hunting of whitecoats and bluebacks through a prohibition on the sale, while at the same time allowing for a limited harvesting of these animals for non-commercial purposes. Stated another way, the "mischief" that Parliament sought to remedy was the large-scale commercial hunting of whitecoats and bluebacks. This was done to preserve the economic viability of not only the seal fishery, but the Canadian fisheries in general." [4]
Consequently, the "pith and substance' of the law was found to be in relation to the "management of the Canadian fishery" [5] which McLachlin found would fall within the federal fisheries power under section 91(12) of the Constitution Act, 1867.
Pith and substance is a legal doctrine in Canadian constitutional interpretation used to determine under which head of power a given piece of legislation falls. The doctrine is primarily used when a law is challenged on the basis that one level of government has encroached upon the exclusive jurisdiction of another level of government.
