Vance provides security services. The company was hired by the government of Saudi Arabia to help with security for Princess Anud, a wife of King Fahad, while she was undergoing medical treatment in California. Security was supervised by the Saudi military. Vance hired Butters as a part-time, at-will security agent in the team guarding the Saudi royal family. Vance recommended she serve a full rotation in the command post at the family’s California residence. The Saudi officer in charge of security rejected that recommendation, saying it would violate Islamic law for a woman to be in a command position and that the Princess only wanted to speak to male officers when she called the command post. Butters quit and sued Vance for sex discrimination. The district court entered summary judgment for Vance. Butters appealed; does she have grounds?
