Massachusetts Criminal Law and Procedure
What this domain tests
The Massachusetts Criminal Law and Procedure domain asks you to connect statutory elements to lawful police action from encounter through arraignment. Expect questions that require you to name the offense, identify each element, and then justify the arrest, search, or charging decision under Massachusetts law.
Core rules
- Offenses are defined by the General Laws; the common law supplies some elements and defenses. Know the elements of the charged crime before you arrest.
- Warrantless felony arrests require probable cause. For misdemeanors, arrest authority is offense-specific; check the statute rather than assuming a general power.
- Article 14 of the Massachusetts Declaration of Rights can be more protective than the Fourth Amendment. The exclusionary rule applies, and Massachusetts does not recognize a good-faith exception for defective warrants.
- A search incident to arrest is limited to the arrestee's person and the area within immediate control; a vehicle search needs a separate theory.
- Bail and dangerousness are governed by G.L. c. 276; the arraignment is the first court appearance and triggers counsel issues.
Worked example
An officer sees a man throw a rock through a store window at night, reach in, and take a display item. The officer has probable cause for breaking and entering with intent to commit a felony under G.L. c. 266 and can arrest without a warrant. The search incident to arrest covers the man's pockets and the area within his immediate reach, not the entire store or a locked cabinet. If the man is in a car, the passenger compartment is not automatically searchable; the officer must articulate a separate exception.
Traps
Treating federal standards as identical to Massachusetts law; assuming automatic standing issues do not apply; arresting for a misdemeanor not committed in the officer's presence without statutory authority; and omitting an element from the complaint application.
