A federal judge in New York is blocking the Justice Department from obtaining identifying and clinical records subpoenaed from NYU Langone Hospitals while the court reviews constitutional challenges to those demands.U.S. District Judge Katherine Polk Failla issues a temporary restraining order, grants class-action status to minors, parents and young adults, and says the subpoenas sweep six years of records without a legitimate investigative purpose.The subpoenas are tied to a Food and Drug Administration probe into alleged drug misbranding, and plaintiffs led by the American Civil Liberties Union argue the Justice Department is using criminal subpoenas after failing in civil litigation.The order bars hospital staff from producing sensitive information while the court schedules a hearing to consider a broader preliminary injunction and the decision could limit future federal access to medical data in politically charged probes.
