Selected case law

McDonough v. Whalen, 365 Mass. 506, 512 (1974)
The plaintiffs sued for property damage and personal injuries caused by the negligent design and installation of a home septic system.  The court held “a builder or contractor may be liable for injuries or damage caused by his negligence to persons with whom he has no contractual relation and even though his work is completed and accepted by the owner before the injuries or damage occurred.”

Tortorella v. Board of Health of Bourne, 39 Mass. App. Ct. 277, 281 (1995)
When deciding whether to grant a variance from Title 5 requirements, the Board of Health may consider “other factors that are relevant to potential demands on the system.”  The broad discretion given to the Board is “based on the strong public interest in protecting health and the environment.”

Vanderwiel v. Jones, 1996 Mass.App.Div. 184 (1996)
Real estate broker violated M.G.L. c. 93A when she “…negligently convinced the buyer not to have septic system inspection.”  Court found that language in purchase and sale agreement releasing broker from liability for misrepresentation of facts was “against public policy and void.”
