Under Marshall’s leadership for more than 34 years—the longest tenure for any chief justice—the Supreme Court set forth the main structural lines of the government. Initially, there was no consensus as to whether the Constitution had created a federation or a nation, and although judicial decisions could not alone dispel differences of opinion, they could create a body of coherent, authoritative, and disinterested doctrine around which opinion could mass and become effective. To the task of creating such a core of agreement Marshall brought qualities that were admirably adapted for its accomplishment. His own mind had apparently a clear and well-organized concept of the effective government that he believed was needed and was provided by the Constitution. He wrote with a lucidity, a persuasiveness, and a vigor that gave to his judicial opinions a quality of reasoned inevitability that more than offset an occasional lack in precision of analysis. His tenure gave opportunity for the development of a unified body of constitutional doctrine. It was the first aspect of Marshall’s accomplishment that he and the court he headed did not permit this opportunity to pass unrecognized.

Marshall distinguished himself from his colleagues by wearing a plain black robe, in stark contrast to the scarlet and ermine robes worn by the other justices. Prior to Marshall’s appointment, it had been the custom of the Supreme Court, as it was in England, for each justice to deliver an opinion in each significant case. This method may be effective where a court is dealing with an organized and existing body of law, but with a new court and a largely unexplored body of law, it created an impression of tentativeness, if not of contradiction, which lent authority neither to the court nor to the law it expounded. With Marshall’s appointment—and presumably at his instigation—this practice changed. Thereafter, for some years, it became the general rule that there was only a single opinion from the Supreme Court. Indeed, Marshall’s term was marked by great consensus and stability on the court; Marshall only dissented formally once during his tenure, and between 1811 and 1823 the Supreme Court’s personnel did not change—the longest such period in history. This change of practice alone would have contributed to making the court a more effective institution. And when the opinions were cast in the mold of Marshall’s clear and compelling statement, the growth of the court’s authority was assured.

Marbury v. Madison (1803) was the first of Marshall’s great cases and the case that established for the court its power to invalidate federal laws and acts found to be in conflict with the Constitution. The foundation of the case and the significance of its ruling must be understood within the historical and strategic context of the time. Shortly before the expiration of President Adams’s term, the Federalist-controlled Congress created and Adams filled a number of federal judicial positions. The commissions of the judges had been signed and the seal of the United States affixed in the office of the secretary of state (Marshall’s office), but some of them, including that of William Marbury, remained undelivered. (Ironically, Marshall, as secretary of state, was responsible for delivering these appointments.) Offended by what he perceived to be a Federalist court-packing plan, President Jefferson ordered his secretary of state, James Madison, to halt delivery of the remaining commissions.

Marbury unsuccessfully petitioned the Department of State for his commission, and subsequently he instituted suit in the Supreme Court against Madison. Although the matter was not beyond question, the court found that Congress had, under the authority of Section 13 of the Judiciary Act of 1789, authorized that such suits be started in the Supreme Court rather than in a lower court. The court faced a dilemma of historic proportions. If it issued a writ of mandamus ordering Madison to deliver the commission, it was clear that such a command would be ignored, thereby undermining the court’s influence for generations, but if it failed to issue the writ the Supreme Court would be seen as cowering in the face of presidential power. Under Marshall’s direction, the Supreme Court altered the issue at hand, and, speaking through Marshall, the court held that Article III of the Constitution did not permit this expansion of the court’s original jurisdiction and that the court could not follow a statute that was in conflict with the Constitution. It thereby confirmed for itself its most controversial power—the function of judicial review, of finding and expounding the law of the Constitution.

Throughout Marshall’s tenure as chief justice, the Supreme Court held only one term each year, lasting about seven or eight weeks (slightly longer after 1827). Each justice, however, also conducted a circuit court—Marshall in Richmond, Va., and Raleigh, N.C. Marshall’s conflict with the Jefferson administration erupted once more in 1807 in Richmond, where Marshall presided at the treason trial of former Vice President Aaron Burr, successfully frustrating President Jefferson’s efforts toward a runaway conviction; as a result, Burr was freed. With hardly more than three months annually engaged in judicial duties (at that time, the court’s docket was much smaller than it is today), Marshall had much time to devote to personal endeavors. In 1807 he completed the five-volume The Life of George Washington. He also served (1812) as chair of a commission charged with finding a land and water route to link eastern and western Virginia, and in 1829 he was part of the Virginia state constitutional convention.

Once the power of judicial review had been established, Marshall and the court followed with decisions that assured that it would be exercised and that the whole body of federal law would be determined, in a unified judicial system with the Supreme Court at its head. Martin v. Hunter’s Lessee (1816) and Cohens v. Virginia (1821) affirmed the Supreme Court’s right to review and overrule a state court on a federal question, and in McCulloch v. Maryland (1819) the Supreme Court asserted the doctrine of “implied powers” granted Congress by the Constitution (in this instance, that Congress could create a bank of the United States, even though such a power was not expressly given by the Constitution).

McCulloch v. Maryland well illustrated that judicial review could have an affirmative aspect as well as a negative; it may accord an authoritative legitimacy to contested government action no less significant than its restraint of prohibited or unauthorized action. The ruling, which nearly precipitated a constitutional crisis, upheld the authority of the federal government and denied to the states the right to impose a tax on the federal government. Faced with the daunting task of explaining where the authority of the Congress to create a bank is located in the Constitution, Marshall turned to Article I, Section 8, Paragraph 18, which grants to the federal government the power to “make all laws which shall be necessary and proper” for carrying out the powers it was explicitly granted in the Constitution. The ruling infuriated states’ rights advocates, leading several, including judges Spencer Roane and William Brockenbrough, to admonish Marshall and the court through the press. In an unprecedented move, Marshall replied under an assumed name, writing as “A Friend to the Constitution.”

In commerce law Marshall led the court in deciding a number of cases brought in response to the emerging American economy and the government’s attempts to regulate it. Fletcher v. Peck (1810) and the Dartmouth College case (1819) established the inviolability of a state’s contracts, and Gibbons v. Ogden (1824) affirmed the federal government’s right to regulate interstate commerce and to override state law in doing so. Many of Marshall’s decisions dealing with specific restraints upon government have turned out to be his less-enduring ones, however, particularly in later eras of increasing governmental activity and control; indeed, it has been in this area that judicial review has evoked its most vigorous critics.

Outside the court, Marshall spent much of his time caring for an invalid wife. He also enjoyed companionship, drinking, and debating with friends in Richmond. In general, for the first 30 years of his service as chief justice, his life was largely one of contentment. In late 1831, at age 76, Marshall underwent the rigors of surgery for the removal of kidney stones and appeared to make a rapid and complete recovery. But the death of his wife on Christmas of that year was a blow from which his spirits did not so readily recover. In 1835 his health declined rapidly, and on July 6 he died in Philadelphia. He was buried alongside his wife in Shockoe Cemetery in Richmond.
