This case concerns whether police may access private and sensitive medical records without a warrant as part of a criminal investigation of an individual, when those records are contained within state prescription drug monitoring databases.

During the 2014-2015 Ebola outbreak, state officials quarantined multiple people who had arrived in the United States from Liberia, without adequate scientific justification, thereby violating their constitutional rights.

The ACLU and its Oregon affiliate are challenging the federal Drug Enforcement Administration's claim that it can access Oregonians' private prescription records without a warrant. The ACLU and the ACLU of Oregon represent a group of Oregon patients and a physician who are concerned about the impact on medical privacy and the doctor-patient relationship if federal law enforcement were permitted to access prescription records without demonstrating probable cause to a neutral judge. A district court judge ruled in February 2014 that patients have a reasonable expectation of privacy in their prescription records and that law enforcement must obtain a warrant in order to search such information. In June 2017, the Ninth Circuit Court of Appeals reversed the district court’s ruling on procedural grounds but recognized that medical records are private and sensitive and require strong legal safeguards, leaving the door open to future challenges.
