2. In the States where death penalty is still in use, a death sentence can be pronunced only for the heaviest crimes, attending the laws that were on when the crime was committed and only if it isn't against the disposition of the Pact or the Convenction for the prevenction and the punishment of the murder of a whole people. This penalty can be executed only after the final condemnation, done by a competent court.
