Her Majesty The Queen in Right of the Province of Saskatchewan, 2015 SCC 4
This constitutional labour appeal addressed whether a statutory prohibition on designated essential-services employees striking substantially interfered with meaningful collective bargaining under s. 2(d) of the Charter.
The Court held that the right to strike is an indispensable component of meaningful collective bargaining, and that the statutory scheme’s unilateral employer designations and lack of a meaningful impasse-resolution substitute rendered the infringement unjustified under s. 1.
The declaration of invalidity concerning the essential-services regime was suspended for one year.
The companion challenge to amendments governing union certification, decertification, and employer communications was dismissed.
