I would just point out that the other provisions of the act continue to apply. If the minister were to deny a case using (l) and using a factor that others considered questionable, the minister would be obligated to provide written reasons to an applicant where a denial is issued. Those reasons would be on the record and of course would then be subject to judicial review if the applicant felt so inclined.
