William Dexter Wilson and Samuel Alfred Foot, Attainder of Treason and Confiscation of the Property of Rebels (1863)
“ They might be passed against any political opponent who might happen to be in a minority; or against any man, after he was dead, whose property the King or Parliament might wish to secure. This most odious engine of despotism has been abolished in this country. Here, "no bills of attainder may he passed." But attainder itself—that is, loss of political and civil rights—is not abolished in this country. It may be inflicted as a penalty for treason or rebellion, or other crime, only it must be by trial and conviction; it cannot be by bill or mere act of Congress. ”
