The proposed law provides that the official ballot in the biennial State election for the year 1970 shall contain a question asking the voters whether there shall be a convention in 1971 to (1) revise, alter or amend the constitution of the Commonwealth on the following subject, insofar as they relate to the structure of government, and no others: the Executive Branch; the General Court; the Executive Council; the government of cities; towns and counties and their relationship to each other and to the government of the Commonwealth; (2) simplify and rearrange the constitution, and (3) provide methods of amendment thereof. The question will state that the convention shall not consider or propose any measure which relates to the Massachusetts Declaration of Rights, the provisions of the Massachusetts constitution concerning the "Judiciary Power" (other than provisions respecting the Executive Council), or any of the excluded matters enumerated in Article XLVIII, 11, Section 2 of the Massachusetts constitution.
The question will fix the number of delegates to the convention at 150, of whom 20 members shall be members of the General Court; the remaining 130 members shall be elected by the votes in the manner summarized below. The Question will also state that the convention shall conclude its business but later than 120 days from its first session.

The proposed law provides that if a majority of the votes on the foregoing question is in the affirmative, the convention shall be held in July, 1971 to revise, alter or amend the constitution on the matters enumerated above only. The House of Representatives and the Senate shall each elect as delegates 10 of its members, not more than 6 from each branch coming from the same, not more than 6 from each branch coming from the same political party. Of the remaining 130 delegates, 10 shall be elected at large and 120 shall be elected from the 40 senatorial districts. 3 from each. Provision is made for the manner of nominating and electing these 140 delegates, without party or political designation, for filling vacancies occurring in the position of any delegate, form whatever source chosen, and for the conduct of the convention's business.

Any revisions, alterations and amendments of the Massachusetts constitution adopted by the convention shall be submitted to the people at the State election in 1972 for their ratification and adoption in such manner as the convention may direct. If a majority of the people voting thereon ratify and adopt such revision, alteration or amendment, the constitution shall be deemed to be changed accordingly.

The proposed law also provides that if the vote on the question to be submitted at the biennial State election in 1970 is in the affirmative, the Governor shall appoint a proprietary commission of 5 members to compile data to aid the convention in the discharge of its duties. Each member of the commission shall receive compensation of $10,000 and the commission may expend a sum not in excess of $200,000, as the Governor may approve, for its expenses.
