People v. Superior Court of Riverside Cnty.

INTRODUCTION

On November 8, 2016, the voters passed Proposition 57, 1 and the new law became effective the following day.

We must determine whether Proposition 57 applies to a pending case that the People directly filed in Adult Court against real party in interest, Jeremy Walker, several years prior to the effective date of the new law. We conclude that Proposition 57 does not apply to Walker's case and that the trial court's transfer of Walker's case from Adult Court to the juvenile court (Juvenile Court) pursuant to the new law was erroneous. 3 Accordingly, we grant the People's writ petition and direct the trial court to vacate its order transferring Walker's case from Adult Court to Juvenile Court.
