Johnson worked for Security Agents, Inc. as a security guard at a building in New York City owned by the Abu Dhabi Investment Authority, a sovereign wealth fund owned by the government of Abu Dhabi. While the building was being renovated, Johnson slipped and fell on something "that had been spilled on the floor." Contending that he suffered permanent injuries in the fall, he sued the Abu Dhabi government in tort for his injuries. The district court dismissed the suit, holding that the government was immune due to the Foreign Sovereign Immunities Act. Johnson appealed. Does the Act bar his suit
