When you say the new law that took affect on October 1, 2011, I am assuming that you are referring to AB109 also known as the Public Safety Realignment Act. The answer is no, it will have no effect on his parole if he was placed on parole before October 1, 2011.
He must be advised of the parole violation allegation within three days of arrest and must go before the parole hearing within 15 days of arrest.
I cannot say with certainty how long they will give him, however I would suspect that he would get either a treatment program or six months eligible which means he only has to do half time.
As to the punishment from the Superior court, it will probably be less than the parole violation so there will be no additional jail time. There will be additional things that he must do to get his license back.Ask a similar question
He is looking at a parole violation as well as a new law violation. The new law AB109 will not assist you. No one can say with certainty what kind of sentence he will receive.
