This year marks the 200th anniversary of the Supreme Court’s ruling in McCulloch v. Maryland. In that case, Chief Justice John Marshall upheld Congress’s power to charter a national bank—a distant forerunner of the modern Federal Reserve System.
Nearly all constitutional writers consider McCulloch one of the Supreme Court’s most important cases. They are correct to do so.
There are at least two well-grounded reasons why Marshall’s opinion in the McCulloch ruling is important. The first is that it clarified some basic facts about the constitutional system.
The McCulloch ruling explained that the people, not the states, created the federal government and granted its powers. As a young lawyer, Marshall had been a leading spokesman for the Constitution, particularly in Virginia. In McCulloch, Marshall said—as James Madison had before him—that the Constitution’s legal force comes from approval by popularly elected state ratifying conventions that met from 1787 through 1790.
It follows that the first rule of constitutional interpretation is the understanding of the ratifiers. It isn’t, as some conservatives say, the “intent of the framers” or “the original public meaning.” Nor should we, some liberals contend, construe the Constitution through “evolving social standards” or novel interpretive theories.
Moreover, the McCulloch ruling clarified that, under the Constitution, state and federal governments operate fairly independently of each other. Neither level of government should try to dictate to the other nor obstruct the other’s core functions. Because Congress designed the national bank to assist Congress in carrying out its core functions, McCulloch voided a state attempt to tax the bank.
The second reason the McCulloch ruling is so important is Marshall’s use of established law and legal methods—rather than tailor-made theories—for interpreting the Constitution. This is noteworthy in his discussion of whether the national bank was valid under the Constitution’s necessary and proper clause.
The Constitution lists the powers of Congress. These include such functions as national defense, borrowing money, taxing, the postal system, the monetary system, and regulating foreign and interstate commerce. In addition to these explicit items, the Constitution adds that “the Congress shall have Power ... To make all Laws, which shall be necessary and proper for carrying into Execution” its listed powers.
The Constitution’s list of explicit powers doesn’t include chartering a national bank. In McCulloch, the court had to determine whether chartering the bank was “necessary and proper” to carry out Congress’s explicit powers.
Marshall, like other lawyers of his time, was familiar with documents by which one person or group granted authority to another—documents such as powers of attorney, wills, trust instruments, and statutes. The phrase “necessary and proper” was common in such documents.
As used in the Constitution, the “necessary and proper” phrase meant that in addition to the functions explicitly listed, the person or group receiving authority could exercise incidental powers. These were lesser powers intended to accompany the listed ones. Lesser powers usually were incidental if they were customary or necessary to carrying out the listed functions.
For example, it is customary for a manager hiring employees to investigate candidates before hiring them. So a manager with power to hire employees usually has incidental authority to investigate candidates. Similarly, a real estate broker with authority to sell a vacant building may have incidental authority to clean it for showing.
In like manner, the Constitution’s grant of power to Congress to impose taxes carries with it incidental authority to obtain office space for revenue officers.
Marshall’s McCulloch opinion shows that he understood the necessary and proper clause as embodying the law of incidental powers. He said the Constitution didn’t mention incorporation because incorporation was merely a subsidiary power rather than a “great power” such as national defense and finance. Constitutions, unlike ordinary laws, generally left subsidiary powers to implication. This was the context for Marshall’s famous phrase, “We must never forget that it is a constitution we are expounding.”
Marshall further explained that national banks were customary and necessary for government financial and defense functions.
Marshall used other ordinary legal methods to support his conclusion. For example, he said that, in 1791, leading founders had debated the constitutionality of a national bank both in and out of Congress—and most of them concluded the bank was constitutional. This process of consulting “contemporaneous exposition” was (and is) a traditional way of interpreting statutes and documents. Marshall didn’t resort to novel interpretive theories or evolving social standards.
In the 20th century, the Supreme Court cited the McCulloch ruling to uphold unprecedented federal spending and regulatory programs. Law school constitutional law courses sometimes treat McCulloch the same way.
