Article Three of the United States Constitution
Finally, Section 3 talks about punishment for people found guilty of treason.  It gives Congress the power to decide the punishment.  However, there is one punishment that the Constitution does not allow: punishing a person's family and descendants for that person's crime.  In English law, if a person was convicted of treason, their punishment would include an "Attainder" (also called a "Corruption of Blood").  This meant that not only the person, but their family and heirs, would be punished and thought of as guilty.  Once a person was "attainted," they would be executed.  However, their heirs would also lose the right to inherit that person's land, property, or money.
