The Massachusetts Appeals Court recently suppressed evidence in a case that was seized as a result from an arrest by Boston Police based on mistaken information. In the case of Commonwealth v. Maingrette, the Appeals Court ruled that the arrest, based on a default warrant that was no longer active at the time of the defendant’s arrest, was unlawful and evidence seized as a result must be suppressed.
When “an arrest is wrongly made on the basis of mistaken information chargeable solely to the police, the burden is on the government to show that i twas not at fault in the circumstances” and that the mistake was reasonable.”
