Brown and Brown, Inc. v. Richard Blumenthal

Summary

The court held that materials obtained by the attorney general during a preaction antitrust investigation generally may not be disclosed to anyone outside the attorney general's office, including third parties involved in interviews or depositions. Disclosure to federal or state officials is permitted only if those officials agree to maintain equivalent confidentiality, and investigatory materials later used in court must be lodged so the source can seek sealing or limited disclosure. The court therefore reversed the judgment for the attorney general and directed judgment for Brown and Brown, Inc.
