Outside court the young man's mother said she was relieved to finally have some help.
"I'm relieved, I'm glad someone finally stepped up.
"I feel good about the place he is going, it is better than where he was."
Judge Gerard Lynch commended the work of Stillwell and said although it had opened him up to some criticism, it was his "sterling" efforts that had helped the young man.
"In my view his attention to the matter has created a positive result for this young man."
He said management of the young man's case had been poor "up until Stillwell's involvement".
