Section 12

A local boundary commission or board shall be established by law in the executive branch of the state government. The commission or board may consider any proposed local government boundary change. It may present proposed changes to the legislature during the first ten days of any regular session. The change shall become effective forty-five days after presentation or at the end of the session, whichever is earlier, unless disapproved by a resolution concurred in by a majority of the members of each house. The commission or board, subject to law, may establish procedures whereby boundaries may be adjusted by local action.
