The applicant, a retired school principal, sought an order of prohibition to restrain the Ontario College of Teachers from proceeding with a discipline hearing against him.
The allegations related to his failure to properly screen and discipline a teacher who was later convicted of sexual offences.
The applicant had retired and cancelled his teaching certificate before the professional misconduct regulation came into effect.
The Divisional Court held that the College lacked jurisdiction to apply the professional misconduct regulation retrospectively to a former member who had resigned before the regulation was enacted, as the proceedings would be purely punitive rather than for public protection.
The application for prohibition was granted.
