The Boston City Council is the legislative branch of government for the city of Boston, Massachusetts, United States. It is made up of 13 members: 9 district representatives and 4 at-large members. Councillors are elected to two-year terms and there is no limit on the number of terms an individual can serve. Boston uses a strong-mayor form of government in which the city council acts as a check against the power of the executive branch, the mayor. The council is responsible for approving the city budget; monitoring, creating, and abolishing city agencies; making land use decisions; and approving, amending, or rejecting other legislative proposals.
