A federal appellate panel has upheld a decision to let McDonald’s Corp. out of a lawsuit over an incident in which a restaurant employee was strip-searched at the instructions of a caller posing as a police officer.

According to a district court order recounting the largely undisputed details, the plaintiff was a 19-year-old woman working at a franchisee-owned McDonald’s in Hinesville, Ga., on Feb. 2, 2003, when a caller purporting to be a police officer guided a male maintenance worker through a body-cavity search of the plaintiff.
