MAPS and MPP file an amicus curiae brief in the on-going Raich v. Gonzales case. On June 6, 2005, the US Supreme Court rejected the decision of the 9th Circuit Court of Appeals that there was no interstate commerce, and thus affirmed federal jurisdiction over state medical marijuana laws. However, a new lawsuit making other legal arguments has been filed. The amicus curiae brief describes the federal obstruction of MAPS’ efforts to conduct federally-approved medical marijuana research.
