The Supreme Court’s vote count in McCulloch v. Maryland was unanimous: 7–0, decided on March 6, 1819, with every sitting justice joining Chief Justice John Marshall’s opinion.1Justia. McCulloch v. Maryland No justice dissented. No justice wrote separately. That complete agreement gave the ruling its immediate force as a definitive statement that Congress holds broad implied powers and that states cannot tax federal institutions.
Who Voted and How
All seven justices on the bench signed on to Marshall’s opinion. The Chief Justice wrote for the Court, joined by associate justices Bushrod Washington, William Johnson, Henry Brockholst Livingston, Thomas Todd, Gabriel Duvall, and Joseph Story.1Justia. McCulloch v. Maryland
Story is worth singling out. His grasp of constitutional structure and his intellectual partnership with Marshall helped shape the reasoning in the opinion, and he became one of the most influential justices in the Court’s history. His alignment with Marshall reflected a bench that, during this period, leaned strongly toward strengthening the national government while its authority was still being tested.
Why 7–0 Was Remarkable
The complete agreement was striking because the case touched a raw political nerve. Many states viewed the Second Bank of the United States as a federal power grab, and state legislatures had been openly hostile toward it. Maryland’s suit was one expression of that hostility, and other states were watching closely. A 4–3 split, or even a 6–1 decision with a strong dissent, would have handed opponents of the bank a rallying point and a template for continued resistance.
Instead, every justice reached the same conclusion by the same route. No concurrence offered a narrower rationale that states could exploit. No dissent gave critics language to quote back at the Court. Marshall’s opinion stood alone as the Court’s voice, and that made it far harder to chip away at.
The unanimity also reflected the Marshall Court’s broader approach during this era. Marshall worked hard to build consensus, and the justices of this period shared a general commitment to establishing a functional national government. That internal cohesion produced a string of landmark rulings that shaped American constitutional structure for generations.
How Quickly the Court Moved
Oral arguments began on February 22, 1819, and stretched over nine days, an extraordinary length even by the standards of the early Court. Daniel Webster argued on behalf of James McCulloch and the bank; Luther Martin, a delegate to the Constitutional Convention and a longtime critic of broad federal power, argued for Maryland.2Cornell Law Institute.

Despite nine days of argument, the Court issued its decision just three days later, on March 6. The speed suggests the justices had already formed strong views about the constitutional questions at stake, and it is consistent with a bench that reached its 7–0 result without internal disagreement to work through.
What the Unanimous Vote Settled
The vote resolved two questions at once. First, whether Congress could charter a national bank even though the Constitution nowhere mentions banks. Second, whether Maryland could tax the Baltimore branch of the Second Bank under an 1818 state law that required non-state-chartered banks to use stamped paper or pay $15,000 annually.1Justia. McCulloch v. Maryland
On the first question, Marshall pointed to the broad powers Congress does hold under Article I, Section 8: collecting taxes, borrowing money, regulating commerce, funding armies, and conducting war. A national bank was a practical tool for carrying those out.2Cornell Law Institute. U.S. Constitution Annotated – Early Doctrine and McCulloch v. Maryland The Necessary and Proper Clause, Marshall wrote, did not require Congress to show that a chosen means was absolutely indispensable. It required only that the means be “appropriate and legitimate” for advancing a constitutional objective.3Oyez. McCulloch v. Maryland Marshall also read the Tenth Amendment to reserve to the states only those powers not delegated to the federal government, noting the amendment’s deliberate omission of the word “expressly” that had appeared in the Articles of Confederation.1Justia. McCulloch v. Maryland
On the second question, Marshall invoked the Supremacy Clause and delivered the opinion’s most quoted line: the power to tax is the power to destroy. If Maryland could tax the bank at all, nothing would stop it from setting the rate high enough to shut the branch down, letting a single state override an institution created for the entire nation. Marshall wrote that “a power to destroy, if wielded by a different hand, is hostile to, and incompatible with these powers to create and to preserve.”1Justia. McCulloch v. Maryland The Court struck down Maryland’s tax.
What the 7–0 Result Locked In
Because the decision carried no internal disagreement, its two holdings entered constitutional law without qualification. Congress could choose any appropriate means to carry out its listed powers. States could not tax federal instrumentalities in ways that would substantially interfere with federal functions, a principle later cases refined into what is sometimes called the federal instrumentalities doctrine.4Justia. The Doctrine of Federal Exemption From State Taxation
The interpretive framework a 4–3 Court might have produced would almost certainly have been narrower and more contested. The 7–0 framework Marshall actually delivered has been used to justify federal organization of the court system, enforcement of the Civil War Amendments, effect for treaties with foreign nations, and regulation of local economic activity that substantially affects interstate commerce.5Congress.gov. Modern Necessary and Proper Clause Doctrine Federal labor regulations, environmental laws, and health and safety standards all rest, in part, on the broad reading of congressional power that McCulloch established. The vote count in 1819 is where that reading became settled law.
