Howell Edmunds Jackson (April 8, 1832 – August 8, 1895) was an American attorney, politician, and jurist who served as an Associate Justice of the Supreme Court of the United States from 1893 until his death in 1895. His brief tenure on the Supreme Court is most remembered for his opinion in Pollock v. Farmers' Loan & Trust Co., in which Jackson argued in dissent that a federal income tax was constitutional. Republican President Benjamin Harrison appointed Jackson, a Democrat, to the Court. His rulings demonstrated support for broad federal power, a skepticism of states' rights and an inclination toward judicial restraint. Jackson's unexpected death after only two years of service prevented him from having a substantial impact on American history.
