Judicial Review: Judicial review is the power of the courts to declare laws unconstitutional. It allows judges to review and potentially overturn laws passed by Congress or state legislatures.
Federal Supremacy: Federal supremacy means that federal law takes precedence over state law when there is a conflict between them. This principle was strengthened by Chief Justice Marshall's rulings.
Implied Powers: Implied powers are powers not explicitly stated in the Constitution but reasonably inferred from its language. Chief Justice Marshall's rulings expanded the scope of implied powers for the federal government.
