Describe how the supreme court’s decisions affected the power of the federal government

John Marshall (September 24, 1755–July 6, 1835) was the chief justice of the U.S. Supreme Court (1801–1835) whose court opinions helped lay the basis for American constitutional law.When the Federalists lost the presidency and Congress to Democratic- Republicans, President Adams used his last remaining days of power to entrench as many of his political allies in the judiciary branch as he could, including Marshall. Under Marshall, the Supreme Court adopted the practice of handing down a single opinion of the Court, allowing it to present a clear rule.During his tenure, Marshall made the Supreme Court a third co-equal branch that had the power of judicial review.
