Federal School Segregation Challenge
Fiona Foster, a Black student in the District of Columbia, was denied admission to a nearby public school because of her race under a federal policy. She sued the federal government claiming the policy violated constitutional guarantees. The court applied the Fifth Amendment to strike down the segregation as lacking any rational basis.
State Officer Background Check Mandate
State A sheriff Frank Fisher received a federal directive requiring his deputies to perform background checks on all handgun buyers using a federal database. Fisher refused, arguing the order commandeered state resources. The court held the federal government could not compel state officers to administer the program.
Felicity French and her same-sex spouse, married under State B law, were denied federal tax benefits because a federal statute defined marriage as opposite-sex only. They sued the federal government. The court found the definition violated equal protection by demeaning state-recognized marriages without justification.

Frostline Textiles deposited a federal subsidy check issued by the United States Treasury that bore an allegedly unauthorized endorsement. When the government reversed payment, Frostline invoked a state commercial paper rule protecting good-faith holders. The court applied a uniform federal standard instead of state law.
