In a 7 to 1 decision, the U.S. Supreme Court ruled today that courts of appeals should largely defer to lower courts’ decisions when policing subpoenas issued by the Equal Employment Opportunity Commission (EEOC). By requiring that lower court rulings should be reviewed for abuse of discretion, rather than under a de novo review standard, the Supreme Court’s decision keeps a more sensible, reasonable limit on the EEOC’s investigatory powers, including the scope of requests for information in administrative subpoenas.
