Harris became as a
circuit judge in 1853, In 1858 Harris was appointed by Governor
John J. McRae to a seat on the
Mississippi High Court of Errors and Appeals vacated by the resignation of
Ephraim S. Fisher. His best-known opinion was
Mitchell v. Wells, decided in 1859. The case prohibited a formerly enslaved woman from
inheriting from the
estate of her white father. In essence, it held that once someone was a
slave in Mississippi she would always be considered a slave, even though her father (and owner) had taken her to
Ohio and freed her. The case illustrates the extreme
southern position; it illustrates the uncompromising nature of southern law on the eve of
Civil War. In 1860 President
James Buchanan tendered him the appointment to a seat on the
Supreme Court of the United States, but Harris declined "because of the impending secession". ==Civil War==
