The “midnight judges” were a group of last‑minute Federalist federal judges appointed by President John Adams in the final days and even final night of his presidency in early 1801, just before Thomas Jefferson took office.

Who the midnight judges were

  • They were new federal judgeships created by the Judiciary Act of 1801 , quickly filled by Adams between February and March 1801.
  • The most famous name linked to them is William Marbury , appointed justice of the peace for the District of Columbia, whose blocked commission led to the landmark Supreme Court case Marbury v. Madison.
  • In total, Adams and the Federalist‑controlled Senate filled 16 new circuit court judgeships plus various other posts, all seen as part of this late‑hour effort.

Why they were called “midnight” judges

  • The nickname comes from the claim that Adams was signing commissions up to midnight on his last day in office , trying to entrench Federalist influence in the courts.
  • These appointments followed the bitter election of 1800 , which Adams lost to Jefferson, making the rush look like a partisan move to keep Federalists in power through the judiciary.

What happened to the midnight judges

  • When Jefferson and his Democratic‑Republicans took power, they repealed the Judiciary Act of 1801 with the Judiciary Act of 1802 , abolishing the new circuit courts and effectively removing many of the midnight judges.
  • Jefferson’s administration also refused to deliver some commissions , including Marbury’s, which led to Marbury v. Madison (1803) and the Supreme Court’s assertion of judicial review —the power to strike down laws as unconstitutional.

Why the midnight judges matter today

  • They illustrate how parties have long tried to use late‑term judicial appointments to shape the future, a pattern still debated in modern U.S. politics.
  • Through Marbury’s blocked appointment, they indirectly triggered one of the most important decisions in U.S. constitutional law, defining the Supreme Court’s role as final interpreter of the Constitution.

TL;DR: The midnight judges were Federalist judges hurriedly appointed by President John Adams in early 1801 under the Judiciary Act of 1801, in a last attempt to secure Federalist control of the federal courts before Thomas Jefferson took office; their fate and Jefferson’s response led directly to Marbury v. Madison and the establishment of judicial review.
