Proposal for a legislative amendment to the Constitution establishing an independent redistricting commission

This bill proposes a constitutional amendment to create an independent redistricting commission in Massachusetts that would draw state legislative and congressional district lines. The commission would be composed of members appointed by state officials and political leaders, with specific rules ensuring that district lines are not drawn to favor any political party or dilute the voting strength of racial or ethnic groups. Key provisions require districts to be contiguous and roughly equal in population while prioritizing the preservation of neighborhoods and municipal boundaries over partisan interests. The bill also sets the federal census as the basis for redistricting every ten years and adjusts the residency requirements for state representatives and senators.
