Filing a bill puts an idea before the Legislature. Most bills are not voted on as filed: committees often combine several bills into one new bill, so a law can include a legislator’s idea without carrying their bill number. MassVoter lists what was filed, not what passed. Bills marked “by request” were filed for a constituent, as the state constitution’s right of petition allows, and may not reflect the legislator’s own view.

Jacob R. Oliveira signed on as a co-sponsor of 855 bills filed by other legislators this session. Co-sponsoring means adding your name in support when a bill is filed; it is not a vote. Sorted by subject from each bill’s title; a bill can fall under more than one.
