The Supreme Court noted that for an ordinance to be valid, it must not only be within the corporate powers of the local government unit to enact and must be passed according to the procedure prescribed by law, it must also conform to the following substantive requirements:
(1) must not contravene the Constitution or any statute;
(2) must not be unfair or oppressive;
(3) must not be partial or discriminatory;
(4) must not prohibit but may regulate trade;
(5) must be general and consistent with public policy; and
(6) must not be unreasonable.
