The law of Massachusetts consists of several levels, including constitutional, statutory, regulatory, case law, and local ordinances. The General Laws of Massachusetts form the general statutory law.
Pursuant to certain statutes, state agencies have promulgated regulations, which along with administrative orders and decisions form part of the body of administrative law.[1] The Massachusetts Register is the bi-weekly publication that contains new and amended (permanent and emergency) regulations, notices of hearings and comment periods, notices of public interest, executive orders by the governor, attorney general opinions, a cumulative table of changes to regulations published during the current calendar year, and a list of acts and resolves passed by the General Court.[1][2] The Code of Massachusetts Regulations (CMR) is the canonical compilation of regulations promulgated by state agencies pursuant to the Administrative Procedures Act and is updated through the Massachusetts Register.[1] Both the Code of Massachusetts Regulations and Massachusetts Register are published by the secretary of the Commonwealth.[1]
