If any section or part of a section of this Charter shall be held invalid by a court of competent jurisdiction, such holding shall not affect the remainder of this Charter, nor the context in which such section or part of a section so held invalid may appear, except to the extent that an entire section or part of a section may be inseparably connected in meaning and effect with the section or part of a section to which such holdings shall directly apply; and if any section or part of a section concerned with election procedures shall be held invalid by such court, the pertinent election procedures set forth in the laws of the State of Rhode Island shall apply.
