Administrative law consists of regulations and orders issued by the executive branch of government. Federal regulations are codified in the Code of Federal Regulations (CFR), after first being published in the Federal Register. The CFR is in 50 titles similar to the arrangement of the United States Code. Each title is subdivided into chapters, subchapters, parts and sections. Each volume contains the text of regulations in force, incorporating those promulgated during the preceding 12 months and deleting those revoked.
State regulations are codified in the Code of Massachusetts Regulations, known as the CMR. State agencies issue regulations that are compiled in the code. The code is update on a bi-weekly basis by the Massachusetts Register.
