It's only fair and reasonable, then, that if during that time of lengthy judiciary process the laws of punishment change, they be given the right to take the lesser punishment for it, if the judicial process is still ongoing.
Alors, si durant un long processus judiciaire, les lois relatives aux sanctions changent, il n’est que juste et raisonnable que l’inculpé ait droit à une sanction moins sévère si l’affaire est toujours en instance.
