Nevertheless, when an applicant demonstrates that application of a law, rule, or regulation violates its rights in some cognizable manner and/or imposes a substantial burden on its religious practice, it shall seek relief from the Planning Board, which relief shall be granted unless it is found that the law, rule, or regulation is in furtherance of a compelling public interest. In the event there is a compelling public interest for the law, rule, or regulation, the Planning Board shall, if possible, grant relief which is the least restrictive means of furthering that compelling public interest.
