No one should be punished twice for the same offense.

Nemo debet bis puniri pro uno delicto.

Double punishment for a single wrong is itself a wrong — once a man has answered for his crime by the sentence of a competent tribunal, that matter is concluded forever.

No man ought to be twice vexed for one and the same cause.

Nemo debet bis vexari pro una et eadem causa.

The prohibition against double jeopardy and duplicative litigation is fundamental — once a matter has been properly determined, it may not be relitigated between the same parties.
