The bill titled "An Act relative to tribal government representation on the Martha's Vineyard Commission" proposes amendments to the existing law regarding the composition of the Martha's Vineyard Commission. Specifically, it seeks to replace the current provision that allows for "one member of the cabinet, or his designee, appointed by the governor" with a new requirement for "1 representative of the Wampanoag Tribe of Gay Head Aquinnah, appointed by the Indian tribal government." This change aims to enhance tribal representation within the commission.

Additionally, the bill removes the third sentence from the fifth paragraph of section 2 of chapter 831 of the acts of 1977, although the specific content of that sentence is not detailed in the provided text. Overall, the proposed legislation emphasizes the importance of including tribal governance in local decision-making processes, particularly in relation to the Martha's Vineyard Commission.
