Massachusetts SJC Holds Search Unlawful Absent Showing of Probable Cause that Defendant Was Not Registered for Use of Medical Marijuana
The rapid liberalization of Massachusetts marijuana policy—including decriminalization of possession of less than an ounce of marijuana and legalization of medical marijuana—has had dramatic consequences for the Massachusetts law regarding search and seizure, offering even some defendants whose conduct has not become legal an unexpected avenue of defense. We have written here before about the Supreme Judicial Court’s holdings that neither smelling marijuana (in a necessarily unknown quantity), nor seeing marijuana in an amount estimated to be less than an ounce, constitutes probable cause for a warrantless search following decriminalization of possession of less than an ounce of the drug. The SJC has now made it clear that the medical marijuana ballot initiative, too, changes the landscape for law enforcement seeking to search for and seize marijuana. The Court’s April 27, 2015 decision in Commonwealth v. Canning held that following passage of that initiative, “a search warrant affidavit setting out facts that simply establish probable cause to believe the owner is growing marijuana on the property in question, without more, is insufficient to establish probable cause to believe that the suspected cultivation is a crime.” To be entitled to a valid warrant, the officer must also establish that the person responsible is not registered to cultivate the marijuana for medical use.
