Execution of the law does no injury.
There is a rule in Roman law, that the execution of the law does no injury.
This principle of Roman law provides that the Execution of the law itself cannot be called as an injury. It one who has been punished cannot claim damages for the loss suffered due to the the punishment, as the punishment was the execution of the law and it is equivalent to no injury. Thus, he/she cannot ask for the damages in such case. The harm/damages suffered by the punished party cannot be considered as injury, as it is the execution of Law.
