The Attorney General of Canada appealed a Divisional Court decision finding that the common law definition of marriage as between 'one man and one woman' violated the equality rights of same-sex couples under s. 15(1) of the Charter.
The Court of Appeal dismissed the appeal, holding that the exclusion of same-sex couples from the institution of marriage demeaned their dignity and was not justified under s. 1 of the Charter.
The Court allowed the cross-appeals on remedy, declaring the existing definition invalid and immediately reformulating it as 'the voluntary union for life of two persons to the exclusion of all others'.
