If any term, condition, or provision of this article shall, to any extent, be held to be invalid or unenforceable by a valid order of any court or regulatory agency, the remainder of this chapter shall be valid in all other respects and continue to be effective. In the event of a subsequent change in applicable law so that the provision which had been held invalid is no longer invalid, such provision shall thereupon return to full force and effect without further action by the city and shall thereafter be binding on the franchisee and the city. (Ord. 645 § 1 (part), 2004)
