The school applied to the British Columbia College of Teachers for the proper certification.
The College rejected Trinity Western's application on the grounds that the school's community standards policy, which applied to all students, faculty, and staff, prohibited "homosexual behaviour".
The College argued that this policy was discriminatory and that it would not be in the public interest to approve the application.
In an eight to one decision, the Court held that the College "acted unfairly" in rejecting Trinity Western's application.
The Court concurred with the lower provincial courts, stating that "[i]n considering the religious precepts of TWU instead of the actual impact of these beliefs on the public school environment, the BCCT acted on the basis of irrelevant considerations."
