Whether the parents had Article III standing based on the Government's allegedly unlawful grant of tax exemptions to racially discriminatory private schools.
Holding
No. The parents alleged neither a judicially cognizable direct injury nor an injury fairly traceable to the IRS's challenged enforcement practices.
Reasoning
Article III confines federal courts to actual cases and controversies. At the constitutional core of standing, a plaintiff must show a personal injury that is fairly traceable to the defendant's allegedly unlawful conduct and likely to be redressed by requested relief. These requirements preserve the separation of powers by preventing federal courts from becoming general forums for complaints about how the Government administers the law.
The Court considered two asserted injuries: the parents' claimed injury from the Government's financial support of discriminatory schools and their children's allegedly diminished opportunity to receive an integrated public-school education. Neither theory, as pleaded, established standing.
