An act passed at a special session of a general assembly shall take effect ninety days after adjournment of the special session unless a different effective date is stated in an act of the general assembly.

All Acts and resolutions of a public nature which are passed prior to July 1 at a regular session of the general assembly and which are approved by the governor on or after July 1, shall take effect forty-five days after approval.
