Article III, Section 3, Clause 1 of the Constitution defines the crime of treason and prescribes its punishment. “Treason against the United States” means to levy war against the United States, or to adhere to their enemies, and give them aid and comfort. To convict a person of treason, either the accused person should have confessed in open court, or two different witnesses should testify on the same “overt” act.
Pursuant to Article III, Section 3, Clause 2, Congress has the power to declare punishment for treason. However, the punishment for treason may not “work corruption of blood, or forfeiture except during the life of the person” so convicted. Therefore, the descendants of someone convicted for treason cannot be considered “tainted” by the treason of their ancestor. Furthermore, Congress can confiscate the property of traitors only during their life time. Upon the death of the traitor, their property must be made inheritable to the descendants of the traitor.
