This case asks the Supreme Court to decide how the federal-officer removal statute, 28 U.S.C. § 1442(a)(1), which allows federal officers and persons “acting under an officer” to remove lawsuits from state to federal courts, applies to federal contractors after a 2011 amendment. In this case, it specifically asks whether three gas and oil’s companies’ production of crude oil sufficiently relates to their contracts to furnish refined aviation gasoline for the federal government during World War II. Chevron, one of the companies involved in this suit, argues that the federal-officer removal statute applies broadly to defendants requesting removal and that wartime oil refining was inherently related to its production of crude oil at the time. Plaquemines Parish, one of multiple jurisdictions that sued the companies for environmental damage, counters that, because Chevron’s refining contracts with the federal government did not address crude production, that production does not sufficiently “relate to” the refining, as required by the 2011 amendment. This case raises significant issues regarding the scope of federal contractors’ ability to litigate in federal forums, the willingness of companies to contract with the federal government, and the effectiveness of congressional amendments over established federal caselaw.
