Regulations form part of the body of law known as administrative law. Regulations set forth standards for public health and safety, licensing of professionals, consumer and environmental protection, among others. Regulations have the force and effect of law-like statutes. They are created and enforced by executive branch agencies, which are given the rulemaking authority by the legislature. Regulations are promulgated by individual state agencies after providing for required public notifications and hearings. Regulations must be filed with the Secretary of the Commonwealth.
The CMR can be difficult to use and understand. The Massachusetts Trial Court Law Libraries have compiled answers to questions such as "How is the CMR organized?" and "Are the electronic versions of CMR as good as print versions?"
