[Published Opinion] Disagreeing with In re A.R. (2018) 24 Cal.App.5th 1076, the Court of Appeal held that when a minor is committed to DJJ, the juvenile court must apply the minor’s pre-commitment credits against the “actual maximum custodial term” set under Welfare and Institutions Code, § 731(b), not the “theoretical maximum exposure term” set under section 726(d)(1).
