A federal judge dismissed a lawsuit by Massachusetts cannabis businesses challenging the federal prohibition on marijuana, ruling that only the Supreme Court can overturn its previous decisions on this matter. The plaintiffs, represented by Boies Schiller Flexner, argued that changes in state-level marijuana regulations should exempt them from the Controlled Substances Act (CSA). However, Judge Mark Mastroianni stated that the relief sought is beyond his court's authority and inconsistent with Supreme Court precedent. The plaintiffs were advised to seek reclassification or removal of marijuana from the CSA through the Supreme Court. The case highlights ongoing legal battles regarding marijuana's federal status and the impact of Supreme Court rulings on state-regulated cannabis industries.
