On June 3, 2011, the U.S. District Court for the Western District of Michigan ordered the Department of Community Health to turn over its records concerning medical marihuana patients.  The Drug Enforcement Administration had subpoenaed the Department of Community Health ("DCH") for medical marihuana information, as part of an on-going investigation.  The DCH had previously refused to release information of medical marihuana users to federal investigators, citing patient confidentiality and claiming that its agents could become liable under the Michigan Medical Marihuana Act, which makes it a misdemeanor offense for the disclosure of confidential information.
