Selected case law

Commonwealth v. Thompson, 87 Mass. App. Ct. 572, 32 NE 3d 1273 (2015) The defendant struck a moored sailboat, and his passenger died from her injuries.  The police officer responding to the accident placed the defendant under arrest.  After the defendant was treated at a hospital, the officer asked him for consent to give a blood sample for chemical testing.  The defendant moved to have the test results suppressed based upon a lack of effective consent.  “The statute prohibiting boating while impaired, like the motor vehicle OUI statute, contains an "implied consent" provision.”  The court found that “the constitutional standard for evaluating consent to a search” does not apply in this case.  The allowance of the defendant’s motion to suppress was vacated and the case was remanded to the Superior Court. 

O’Shaughnessy v. Besse, 7 Mass. App. Ct. 727, 389 NE 2d 1049 (1979) Passenger sued harbormaster and patrolman for injuries caused by speedboat collision with unlit floats.  The Appeals Court affirmed the lower court’s allowance of the defendant’s motion for judgment notwithstanding the verdict.  The court found that the statute does not require lights on a moored vessel, and the operator of the boat was also at fault for his handling of the boat.
