"This site provides an unofficial version of the Session Laws from 1997 to the present and is updated regularly...The vast majority of Session Laws are Acts. Acts include everything from our annual state budget (the General Appropriation Act) and major legislative initiatives to reorganize government agencies. Session Laws that are not codified into the General Laws are called Special Acts and include matters affecting an individual or a particular city or town. A Resolve is most often used when the legislation's only purpose is to establish a special commission to investigate a certain issue."
