In 2010, represented the Université du Québec à Trois-Rivières before the Supreme Court of Canada. In this case, the highest court in the country was asked to determine whether a grievance arbitrator had jurisdiction to hear a dispute in which an employee claimed protection under section 124 of the Act Respecting Labour Standards (A.L.S) (dismissal for good and sufficient cause) when the employee’s collective agreement did not provide for recourse in the event of termination of employment.
Contrary to what the Union had argued, the Supreme Court ruled that section 124 A.L.S could not be implicitly incorporated into collective agreements. Rather, it found that under the “hierarchy of relevant sources” test, section 124 A.L.S had the effect of invalidating any provision of a collective agreement that was contrary to that section.
