The applicant sought leave to intervene in an appeal concerning the constitutionality of workers' compensation legislation that bars private compensation claims.
The applicant was involved in similar pending litigation in another province where her action was stayed pending the outcome of this appeal.
The Supreme Court of Canada granted the motion to intervene, finding that involvement in a similar case can satisfy the interest requirement, particularly to remedy the unfairness of the opposing provincial Attorney General having an automatic right to intervene.
The Court also found the applicant could provide useful and different submissions by ensuring a full adversarial context.
