Whenever any ordinance or part thereof is repealed or modified by a subsequent ordinance, such ordinance or part thereof thus repealed shall continue in force until due publication of the ordinance repealing or modifying the same, unless therein expressly provided otherwise; but no proceeding, right, fine or penalty instituted, created or given, secured or acquired, under any ordinance previous to its repeal or modification, shall in any way be affected, released or discharged, but may be prosecuted, enjoined and recovered as fully as if such ordinance had continued in force, unless it is therein otherwise expressly provided. (Prior code § 1-4-9)
