Translate the following English sentence to French:
"There is therefore reason to require that all cases be investigated, that is to say that the cases of those who are awaiting punishment should be gone through and, for example, investigations made into whether they have received fair trials."
Il y a donc lieu d'exiger que tous les cas soient examinés, ce qui signifie que l'on doit revoir le cas des personnes qui attendent le prononcé de leur peine et voir, par exemple, si elles ont eu droit à un procès équitable.
