O.G. v. Super. Ct., 481 P.3d 648

Background

Proposition 57 (2016) eliminated prosecutors’ direct filing for juveniles, required a judge (not a prosecutor) to decide transfer to adult court, and allowed transfer motions for 16–17-year-olds and limited transfer for some 14–15-year-olds.
Senate Bill 1391 (2018) amended Welfare & Institutions Code §707 to bar transfer to adult criminal court for offenders who were 14 or 15 at the time of the alleged offense (with limited exceptions), restoring a de facto 16‑year minimum transfer age.
Two days after SB 1391 was enacted, Ventura County sought transfer of O.G., who was 15 when charged with murder; the juvenile court found SB 1391 unconstitutional and the Court of Appeal affirmed, creating a split with other appellate panels.
The central legal question presented to the California Supreme Court was whether SB 1391 is a valid legislative amendment to Proposition 57 under Prop. 57’s uncodified amendment clause permitting amendments that are “consistent with and further the intent of this act.”
The Supreme Court applied the Amwest standard (highly deferential): uphold a legislative amendment if, by any reasonable construction of the initiative, the amendment is consistent with and furthers the initiative’s purposes.
The Court unanimously reversed the Court of Appeal, holding SB 1391 is a permissible amendment to Proposition 57 because it furthers Prop. 57’s core purposes (rehabilitation, reducing incarceration/prison population, public safety) and narrows prosecutorial power.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether SB 1391 is a permissible legislative amendment to Prop. 57 under the initiative’s amendment clause	(Real party/DA) SB 1391 is inconsistent with Prop. 57 because Prop. 57’s text permits transfer of some 14–15-year-olds; therefore SB 1391 is an invalid amendment	(O.G./AG) SB 1391 is consistent with and furthers Prop. 57’s rehabilitative and decarceration purposes; the amendment clause allows legislative changes that align with the act’s intent	SB 1391 is a constitutional amendment to Prop. 57 and valid; it furthers the initiative’s core purposes
Proper construction of Prop. 57’s amendment clause — must amendments be consistent with the initiative’s text or its intent?	(DA) The clause requires amendments be consistent with both the act’s text and intent; change deleting transfer eligibility for 14–15-year-olds is inconsistent with the text	(O.G./AG) The clause authorizes amendments that are consistent with and further the act’s purpose/intent; amendments need not mirror existing statutory language	Court adopted the reasonable‑construction approach: amendments need only be consistent with and further the initiative’s intent (not verbatim textual consistency)
Standard of review for legislative amendments to initiatives	(DA) Any doubt should be resolved against the amendment; initiative protections favor limiting legislative change	(O.G./AG) Apply presumption of legislative validity and Amwest’s deferential rule—uphold if any reasonable construction shows consistency with initiative’s purposes	Applied Amwest: presume Legislature acted within authority and uphold amendment if any reasonable construction shows it furthers the initiative’s purposes
