If any provision of a section of these codified ordinances or the application thereof to any person or circumstance is held invalid, the invalidity does not affect other provisions or application of the section or related sections which can be given effect without the invalid provision or application, and to this end the provisions are severable. (ILCS Ch. 5, Act 70, § 1.31)  ('64 Code, § 1-4) (Ord. , passed      )
