Legal Question in DUI Law in California

Sure, I can clarify, but I don't think you will be satisfied with the clarity. 'House arrest' is an issue and decision over which the judge involved has full discretion, as you found by his denial of the motion. It is seldom granted, despite what TV shows would lead you to believe. It is also somewhat expensive if granted. Your remaining course of action would be either a motion for reconsideration of the denial, or an appeal of the denial, neither of which is likely to succeed, BECAUSE the judge had full discretion and did not likely make a 'mistake of fact or law' in doing so. That is what you would have to prove in order to justify your motion or appeal. On the bright side, 'good time credits' will get him out in less than the ordered 'time'.
