People v. A.R. (In re A.R.), 24 Cal. App. 5th 1076

Minor (A.R.), age 18 at disposition, had an extensive juvenile history since age 13 with multiple felony admissions and repeated placements in local programs and camps.
After a March 2017 robbery (admitted), probation recommended placement at Y.O.U.; the district attorney sought DJJ commitment.
The juvenile court held a contested dispositional hearing, concluded less restrictive programs had failed, and committed Minor to the Division of Juvenile Justice (DJJ).
The court set a downward-deviated maximum term of seven years (after aggregating petitions to a 12-year overall maximum) and applied 1,076 days of predisposition custody credit to the 12-year overall maximum, leaving the seven-year term available to DJJ and noting Minor would be in DJJ until age 21 for parole purposes.
Minor appealed, arguing (1) the DJJ commitment was an abuse of discretion because less restrictive options would not be ineffective and there was no specific evidence of probable benefit, and (2) custody credits were applied improperly to the 12-year overall maximum rather than the seven-year court-set term.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether commitment to DJJ was an abuse of discretion / lacked substantial evidence of probable benefit	A.R.: No substantial evidence that DJJ would probably benefit him or that less restrictive placement (Y.O.U.) would be inappropriate or ineffective; cites In re Carlos J.	Respondent: Minor has long history of failed local placements; DJJ offers services and a needed drastic change; court properly weighed criminogenic factors and prior failures	Court: No abuse of discretion; substantial evidence supports probable benefit and that less restrictive placements were inappropriate given prior failures and Minor's age
Whether predisposition custody credits were misapplied to the 12-year overall maximum instead of the seven-year court-set term	A.R.: Credits should reduce the seven-year maximum the court set under section 731; applying credits to 12 years deprived him of their effect	Respondent: Court properly determined overall adult-equivalent maximum (12 years), exercised discretion to set a lower statutory maximum (7 years), then applied credits under section 726 to the overall maximum	Court: No error; credits were applied consistent with statutory scheme (sections 726, 731) and precedent; court did not misuse credits or misunderstand the law
