*Carte blanche: unconditional authority; full discretionary power.
Velo had been given carte blanche over the trial, there was no jury. Mella’s life laid in his hands, actions would be taken on his opinion of events. There was a lot to consider, contradicting accounts and information to examine, but yet none of that really mattered. All that mattered was Velo’s opinion, and Velo didn’t want Mella to live.
