Canadian Foundation for Children, Youth and the Law v Canada (AG)

Canadian Foundation for Children, Youth and the Law v Canada (AG), [2004] 1 S.C.R. 76, 2004 SCC 4 - known also as the spanking case - is a leading Charter decision of the Supreme Court of Canada where the Court upheld section 43 of the Criminal Code that allowed for a defence of reasonable use of force by way of correction towards children as not in violation of section 7, section 12 or section 15(1) of the Charter.
Background.
The Canadian Foundation for Children, Youth and the Law ("Foundation") applied for a declaration to strike-down section 43 of the Criminal Code which states, under the section entitled "Protection of Persons in Authority", 
The basis of which is because the provision violates: 
Ruling.
The Supreme Court handed down its 6 to 3 decision on January 30, 2004.
The majority opinion was written by Chief Justice McLachlin with Gonthier, Iacobucci, Major, Bastarache and LeBel JJ. concurring.
Section 7.
Section 7 protects individuals from violation of their personal security. McLachlin found that there was no violation of the section. The Crown had conceded that the law adversely affected the child's security of person, so the issue was whether the violation offended a principle of fundamental justice. The Foundation proposes three claims as mentioned above. McLachlin rejected the first claim that it failed to give procedural protection as children receive all the same protection as anyone else. On the second claim, she rejects that the "best interests of the child" is a principle of fundamental justice as there is no "consensus that it is vital or fundamental to our societal notion of justice."
On the third claim she rejects the claim that the law is vague and overbroad on grounds that the law "delineates a risk zone for criminal sanction". She examines the meaning of "reasonable under the circumstances" stating that it includes only "minor corrective force of a transitory and trifling nature", but it does not include "corporal punishment of children under two or teenagers", or "degrading, inhuman or harmful conduct" such as "discipline by the use of objects", "blows or slaps to the head" or acts of anger. The test is purely objective, McLachlin claims.
Section 12.
Section 12 prevents "cruel and unusual punishment". Citing the standard of showing cruel and unusual punishment from "R. v. Smith" [1987] 1 S.C.R. 1045 as "so excessive as to outrage standards of decency", McLachlin rejects the claim as the section only permits "corrective force that is reasonable" thus cannot be excessive by definition.
Section 15(1).
Section 15(1) is the equality guarantee that protects individuals from discrimination. McLachlin examines the claim using the analytical framework from "Law v. Canada".
When identifying from whose perspective the analysis must be, McLachlin notes that rather than take the perspective of a young child, which would prove too difficult, it must be viewed from the perspective of a "reasonable person acting on behalf of a child" and apprised of the law.
McLachlin says that the claim hinges on demonstrating the lack of "correspondence between the distinction and the claimant's characteristics or circumstances" (the second contextual factor from the "Law v. Canada" test). On this point she acknowledges that children need to be protected, and in furtherance of this goal parents and teachers require protection as well. Section 43 decriminalizes "only minimal force of transient or trivial impact" and to remove such protection would be dangerous as it would criminalize acts such as "placing an unwilling child in a chair for a five-minute "time-out"" which would risk destroying the family.
