Most Supreme Court cases are narrow technical rulings. Cases become landmarks when they resolve fundamental questions about rights, powers, or the Constitution's meaning.

Three markers:

1. Addresses major constitutional question: The case involves core rights (speech, religion, due process) or structural powers (federalism, separation of powers, checks and balances).
2. Creates new legal standard: The ruling establishes a test or framework that lower courts apply to future cases, like Miranda warnings or the strict scrutiny test.
3. Overturns precedent or shifts doctrine: The decision breaks from past rulings, expanding rights (Loving v. Virginia legalizing interracial marriage) or restricting them (Dobbs overturning Roe).

Landmark cases often emerge from social movements. Civil rights groups, advocacy organizations, and test case strategies deliberately bring challenges to push the Court toward constitutional change. The NAACP spent decades building the legal foundation for Brown v. Board through earlier school segregation cases.
