MacKay v. DEA
Petitioner Dewey MacKay, M.D. petitioned the Tenth Circuit to review a decision of the Deputy Administrator of the Drug Enforcement Administration (DEA) that revoked his registration to dispense controlled substances and denied all pending requests for renewal of modification. This case concerned Petitioner's prescribing behavior from 2005 to 2009 when his practice focused primarily on chronic pain management. The DEA began investigating Petitioner after receiving information from local authorities that he was issuing unlawful prescriptions for controlled substances. the Deputy Administrator of the DEA issued an order to show cause why it should not revoke Petitioner's registration, alleging that Petitioner "issued numerous purported prescriptions for controlled substances without a legitimate medical purpose outside the usual course of professional practice." The Tenth Circuit denied Petitioner's petition for review: "Petitioner never admitted any fault or taken responsibility for his misconduct. Nor [could] he point to any evidence that he reformed his habits. Instead, he continued to illegitimately dispense controlled substances even when he knew the DEA was investigating him. The Deputy Administrator’s revocation of [Petitioner's] registration is consistent with the DEA’s policy and practice of revoking registration under such circumstances."
