By authority granted by the Confiscation Acts of 1861 and 1862, the constitutionality of which was upheld by the Supreme Court in the Prize Cases (67 US 635)decision issued in 1863. Under the Confiscation Acts, the federal government could seize any private property without compensation if it was being used to further the cause of the Southern rebellion. Since Northern states were not in rebellion the law did not apply to them.
