Massachusetts v. Mellon
The Court dismissed both a state's lawsuit and a taxpayer's lawsuit challenging a federal law that gave states money to reduce maternal and infant deaths, ruling that neither had a legal right to bring the case in the first place.
The decision established a lasting rule that ordinary taxpayers cannot sue the federal government simply because they object to how it spends money, and that a state cannot sue on behalf of its citizens against a federal law that merely offers, rather than forces, a choice.
“The party who invokes the power must be able to show not only that the statute is invalid but that he has sustained or is immediately in danger of sustaining some direct injury as the result of its enforcement, and not merely that he suffers in some indefinite way in common with people generally.”
The Court's core rule for who has standing to challenge a federal law in court.
How it got here: Massachusetts sued directly in the Supreme Court; Frothingham's suit was dismissed by a D.C. trial court and affirmed by the D.C. Court of Appeals before reaching the Supreme Court.
The Case in Depth
What happened
Congress passed the Maternity Act of 1921, offering federal money to states that agreed to programs reducing maternal and infant mortality, with a federal bureau overseeing how the money was spent. Massachusetts, which had not accepted the funds, sued directly in the Supreme Court, arguing the law usurped powers reserved to the states. Separately, Frothingham, a federal taxpayer, sued in the District of Columbia courts, arguing the spending would eventually raise her taxes without due process.
The question before the Court
Could a state or an individual taxpayer sue to block a federal spending law just because they believed it invaded powers reserved to the states?
Why it matters
The ruling closed the courthouse door to most taxpayer lawsuits against federal spending programs, meaning citizens generally cannot challenge how Congress spends money just because they pay taxes. It also confirmed that federal grant programs offering money to states in exchange for following certain rules do not, by themselves, violate state sovereignty, a framework still used to design programs like federal highway funding and Medicaid.
What changes now
Both cases end here: the original suit by Massachusetts is dismissed, and the judgment against Frothingham is affirmed, without any court ever ruling on whether the Maternity Act itself was constitutional. The decision does not resolve the underlying question of the spending law's validity, but it sets a lasting jurisdictional barrier that later taxpayers and states would have to navigate before bringing similar challenges to federal spending programs.
What this does not decide
The Court did not decide whether the Maternity Act was constitutional or whether Congress had exceeded its spending powers. It ruled only that neither Massachusetts nor the taxpayer had shown the kind of direct, concrete injury needed to bring the challenge to court at all.
How the Court got there
The legal reasoning, step by step
- The Court explained that its power to hear a case involving a state depends not just on a state being a party, but on the dispute being a genuinely justiciable one — a real legal controversy a court can resolve, not just a political disagreement about power.
- Applying that principle, the Court found Massachusetts was not being forced to do anything: the statute only offered federal money in exchange for voluntary compliance, so no legal right or obligation of the state was actually being invaded.
- The Court held that a complaint framed only as Congress overstepping its constitutional authority, with no concrete harm done or threatened, is a political question about the scope of government power rather than a judicial dispute about rights, and courts cannot resolve such abstract disputes.
- Turning to whether Massachusetts could sue on behalf of its citizens, the Court reasoned that citizens' relationship with the federal government is represented by the United States itself, not by individual states, so a state cannot act as a protector of its people against federal law in this way.
- For the taxpayer's suit, the Court reasoned that a federal taxpayer's stake in the U.S. Treasury is shared with millions of others and is too small, indirect, and uncertain to support a lawsuit, unlike a municipal taxpayer's more direct and immediate interest in local funds.
- Because allowing one taxpayer to sue over a spending law would open the door to any taxpayer challenging any appropriation, the Court concluded that policing how Congress spends money is a matter for the political process, not for a lawsuit, absent a showing of direct personal injury.
