No section or provision of this charter may be repealed or amended unless the act making the repeal or amendment refers specifically to this charter and to the sections or provisions so repealed. Any amendment to this charter must be submitted to the voters for their approval and, upon approval, submitted as provided by statutes. Amendments may be placed on the ballot by the Selectboard, a duly authorized Charter Review Commission appointed by the Selectboard, or upon petition filed with the Town Clerk by 10 percent of the voters. The petition must clearly state the amendment and must be filed at least 45 days before any annual or special Town election, but the Town shall not be required to hold a special Town election solely for the purpose of considering a proposed charter amendment. (Amended 2019, No. M-1, § 2, eff. April 19, 2019.)
