Massachusetts Laws


MGL c.93A - Regulation of Business Practices for Consumer Protection - is the main consumer protection law in Massachusetts.  Also known as the Massachusetts Consumer Protection Act, Chapter 93A was enacted in 1967 as a "little FTC Act" - or counterpart to the Federal Trade Commission Act. Under Chapter 93A, any person can sue any other who commits an unfair or deceptive act or practice while engaged in trade or commerce, resulting in loss of money or property.

** See Massachusetts General Laws Annotated (in print or on Westlaw), or Annotated Laws of Massachusetts (in print or on Lexis), for the annotated statute which includes notes of decision and references to other primary and secondary sources.
