Justice / Era Name: John Marshall (The Marshall Court, 1801–1835)
System Title: The Original Architect
Appointed By & Year: John Adams (1801)
Defining Legacy: Transformed the Supreme Court from the weakest, least-respected branch into an equal third pillar of the federal government capable of checking both Congress and the states.
Key System Updates (Major Cases):
- Marbury v. Madison (1803): Established the power of Judicial Review, giving federal courts the authority to declare acts of Congress unconstitutional.
- McCulloch v. Maryland (1819): Upheld federal supremacy and implied powers under the Necessary and Proper Clause, ruling states cannot tax federal operations.
Core Judicial Philosophy: Federalist / Centralized Federal Power — Strongly believed that a unified nation required a powerful federal government and a supreme national court system overriding conflicting state laws.
Signature Move: “It is emphatically the province and duty of the judicial department to say what the law is.” — Marbury v. Madison (1803)
