Step-by-step explanation:
John Marshall became the fourth chief justice of the U.S. Supreme Court in 1801. He is largely responsible for establishing the Supreme Court's role in federal government.
'Marbury v. Madison'
One of Marshall's first landmark cases was Marbury v. Madison, which established the basis of judicial review. The case went to the Supreme Court in 1803, following a hostile history: Toward the end of John Adams's term (while Marshall was serving as secretary of state), Adams had made William Marbury justice of the peace for the District of Columbia. Instead of handing over the commission to Marbury himself, Marshall left the document for his successor as secretary of state, James Madison, to deliver. However, once Thomas Jefferson, Adams's political adversary, took office as president, Jefferson forbade Madison to deliver the commission because it had been drawn up by Adams's supporters. Marbury responded by filing a lawsuit, requesting that the Supreme Court issue a court order forcing Madison to give the commission to Marbury.
Chief Justice John Marshall ruled that the Supreme Court lacked the power to make Madison hand over the commission, although he thought that Marbury had the right to have it. In the process, Marshall determined that Section 13 of the Judiciary Act of 1789—authorizing the Supreme Court to issue writs to government officials—was unconstitutional. Additionally, he concluded that all laws conflicting with the Constitution should be from then on rendered "null and void." In so doing, Marshall instituted the process of judicial review and, subsequently, positioned the judicial branch as equal to its partners in the American government: the legislative and executive branches.
In 1807, Marshall was involved in another high-profile case when President Thomas Jefferson charged Vice President Aaron Burr with treason. To Jefferson's chagrin, Marshall ruled that the prosecution lacked sufficient evidence to prove treason, and charged Burr with a high misdemeanor instead. Marshall set Burr's bail at $10,000. The high misdemeanor case was later sent to a jury, who, based on new evidence, found Burr not guilty.
'McCulloch v. Maryland'
McCulloch v. Maryland, in 1819, was another of Marshall's notable cases. State banks resented the competition of a new national bank that President Madison had opened in 1816. The State of Maryland imposed a tax on the national bank, which the bank refused to pay. Maryland claimed that nothing in the Constitution gave the federal government the right to open a national bank. However, Marshall ruled in the bank's favor, stating that although the Constitution did not explicitly grant the federal government the right to open the bank, the Necessary and Proper Clause of the Constitution did. The bank was spared, and Maryland was not permitted to charge a tax.
