Massachusetts Constitution Amendments Art. II, § 3

Every city and town shall have the power to adopt or revise a charter in the following manner: A petition for the adoption or revision of a charter shall be signed by at least fifteen per cent of the number of legal voters residing in such city or town at the preceding state election. Whenever such a petition is filed with the board of registrars of voters of any city or town, the board shall within ten days of its receipt determine the sufficiency and validity of the signatures and certify the results to the city council of the city or board of selectmen of the town, as the case may be. As used in this section, the phrase “board of registrars of voters” shall include any local authority of different designation which performs the duties of such registrars, and the phrase “city council of the city or board of selectmen of the town” shall include local authorities of different designation performing the duties of such council or board. Objections to the sufficiency and validity of the signatures on any such petition as certified by the board of registrars of voters shall be made in the same manner as provided by law for objections to nominations for city or town offices, as the case may be.

Within thirty days of receipt of certification of the board of registrars of voters that a petition contains sufficient valid signatures, the city council of the city or board of selectmen of the town shall by order provide for submitting to the voters of the city or town the question of adopting or revising a charter, and for the nomination and election of a charter commission.

If the city or town has not previously adopted a charter pursuant to this section, the question submitted to the voters shall be: “Shall a commission be elected to frame a charter for (name of city or town)?” If the city or town has previously adopted a charter pursuant to this section, the question submitted to the voters shall be: “Shall a commission be elected to revise the charter of (name of city or town)?”

The charter commission shall consist of nine voters of the city or town, who shall be elected at large without party or political designation at the city or town election next held at least sixty days after the order of the city council of the city or board of selectmen of the town. The names of candidates for such commission shall be listed alphabetically on the ballot used at such election. Each voter may vote for nine candidates.

The vote on the question submitted and the election of the charter commission shall take place at the same time. If the vote on the question submitted is in the affirmative, the nine candidates receiving the highest number of votes shall be declared elected.

Within eighteen months after the election of the members of the charter commission, said commission shall submit the charter or revised charter to the city council of the city or the board of selectmen of the town, and such council or board shall provide for publication of the charter and for its submission to the voters of the city or town at the next city or town election held at least two months after such submission by the charter commission. If the charter or revised charter is approved by a majority of the voters of the city or town voting thereon, it shall become effective upon the date fixed in the charter.
