I'm waiting for the translation. Don't take it personally, but I am not satisfied with your answer.
I don't think that the Parole Board can override a judge. In certain cases, maybe… If a person has been sentenced to 15 years and has been waiting five years to ask for a pardon, or if that person did nothing wrong in the last 20 years, I cannot accept that you deny her a pardon just because it is going to shock people.
This is not justice in my mind. I have not found the right word for it, but this is not what I call justice.
