People v. Burgos, 292 Cal. Rptr. 3d 587

In 2015 Burgos and co-defendants were tried for second-degree robbery with gang and firearm enhancements; the trial court denied defense motions to bifurcate gang-enhancement evidence and juries found the enhancements true.
While defendants’ appeals were pending, Legislature enacted Assembly Bill 333 (effective Jan. 1, 2022), which (a) substantively narrowed Penal Code §186.22 and (b) added Penal Code §1109, giving defendants the right, if requested, to have gang-enhancement issues tried separately (bifurcation).
The Attorney General conceded the substantive §186.22 amendments are retroactive (per Estrada/Tran) and that true findings on enhancements must be vacated, but argued §1109’s bifuration rule is prospective only.
The Court of Appeal held §1109 retroactive under In re Estrada; the Supreme Court granted review limited to whether §1109 applies retroactively to nonfinal cases.
The California Supreme Court reversed, holding §1109 is a procedural, prophylactic bifurcation rule that does not invoke Estrada’s inference of retroactivity and therefore is presumed prospective under Penal Code §3; it also held prospective application does not violate equal protection.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether Penal Code §1109 (bifurcation of gang enhancements) applies retroactively to nonfinal judgments	People/AG: §1109 is procedural and should apply prospectively only under Pen. Code §3	Defendants: §1109 is ameliorative; under Estrada it should apply retroactively because it reduces wrongful convictions, plea pressure, and may lessen punishment	Held: §1109 is a prophylactic procedural rule; Estrada does not apply; §1109 is presumed prospective and not retroactive
Whether applying §1109 prospectively violates equal protection	People/AG: Rational-basis review applies; Legislature may choose prospective operation and that choice is constitutional	Defendants: Treating similarly situated defendants differently by date of conviction lacks rational justification	Held: Rational-basis review satisfied; equal protection does not compel retroactivity
