St. George Tucker was one of the most influential jurists and legal scholars in the United States late in the 1700s and early in the 1800s. Tucker served as judge on three different courts in Virginia: the General Court (1788–1804), the Virginia Court of Appeals (1804–1811), and the federal district court for the eastern district of Virginia (1813–1825). In addition to his work as a jurist, Tucker was an important legal scholar and educator. From 1788 until 1804, between court terms, Tucker taught law at the College of William and Mary.
Perhaps Tucker's most significant contribution was his 1803 publication of a five-volume edition Commentaries on the Laws of England by William Blackstone. Tucker's "American Blackstone," the first major treatise on American law, helped shape a generation of lawyers and judges. President James Madison appointed him to the federal district court in 1813.
I very much doubt that President Madison would appoint to such a lofty post someone with whom he disagreed.
