A recent hearing before the First Circuit Court of Appeals raised skepticism regarding a challenge to the federal prohibition on marijuana. Litigator David Boies argued that the foundational principles of a 19-year-old Supreme Court precedent on cannabis policy have become outdated, suggesting that its relevance has diminished in light of the current marijuana landscape. This sentiment was echoed by the court, which appeared likely to reject claims from several Massachusetts cannabis businesses asserting that the federal ban is no longer constitutional. Meanwhile, in Colorado, the Court of Appeals ruled that a cannabis attorney could not be held liable for a client's business failure due to land use violations, as the attorney was not representing the client at that time. Additionally, the Nebraska Court of Appeals is being asked to reconsider a lawsuit that aims to overturn recently approved medical cannabis legalization initiatives. In a related development, doctors have requested a postponement of a marijuana rescheduling hearing due to ongoing court challenges concerning the DEA's witness selection process.
