Judiciary Act of 1801
The Judiciary Act of 1801 was a United States federal statute signed into law by President John Adams on February 13, 1801, that reorganized the federal judiciary by creating sixteen new circuit judgeships, establishing dedicated circuit courts, reducing the Supreme Court from six to five justices, and eliminating the requirement for Supreme Court justices to ride circuit.[1][2] The act enabled Adams to appoint Federalist loyalists to these positions in the waning days of his administration, a move derisively termed the "midnight judges" by opponents due to the rushed confirmations before Thomas Jefferson's inauguration on March 4, 1801.[2] Federalists, having lost control of the executive and legislative branches in the 1800 election, viewed the legislation as essential to bolstering a strong, independent federal judiciary capable of countering what they perceived as the Democratic-Republicans' threats to centralized authority and constitutional stability.[2][3] The act's provisions addressed longstanding inefficiencies, such as the burdensome circuit duties on Supreme Court justices, but primarily served to entrench partisan influence in the courts amid fears of Republican dominance.[1][2] The incoming Jeffersonian Republicans swiftly repealed the act through the Judiciary Act of 1802, abolishing the new courts and dismissing most of the appointees, which ignited fierce partisan battles over judicial independence and congressional authority.[2] This repeal prompted legal challenges, most notably Marbury v. Madison (1803), in which Chief Justice John Marshall invoked judicial review to strike down a provision of the earlier Judiciary Act of 1789, thereby establishing the Supreme Court's power to declare acts of Congress unconstitutional while sidestepping a direct confrontation over the 1801 appointments.[2] The episode underscored early tensions between branches of government and highlighted the judiciary's emerging role as a check on legislative overreach, though it also fueled accusations of Federalist entrenchment tactics.[2][4]
