People v. Perez CA5, F082400

Defendant Annabelle Perez was convicted as an accessory after the fact to a murder; the jury rejected the murder defendant’s gang enhancement but found gang enhancements true as to Perez and a codefendant. She was sentenced to 3 years 4 months (including a 2‑year gang enhancement).
At trial substantial gang evidence was admitted about the alleged shooter Nagata (tattoos, wiretapped call, expert testimony about Nuestra Familia); no direct gang evidence tied Perez to gang membership — the prosecution argued her actions still benefited the gang.
Perez moved to bifurcate gang enhancement proceedings and to sever; the trial court denied bifurcation and tried the substantive counts and gang enhancements together in a joint trial of codefendants.
While this appeal was pending, Assembly Bill 333 amended Penal Code § 186.22 and added § 1109 (bifurcation of gang enhancements); People conceded the amended § 186.22 required reversal of the gang enhancement for insufficient proof of a pattern benefiting the gang.
The court held § 1109 applies retroactively to nonfinal cases, concluded the trial court erred by denying bifurcation under § 1109, and found that error prejudiced Perez given the closeness of the evidence against her; the judgment was reversed and remanded for a new trial on the accessory count and gang enhancement.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether AB 333’s amendments to § 186.22 require reversal of the gang enhancement	Gang proof here was sufficient; but People conceded insufficiency under amended § 186.22	AB 333 applies retroactively so the gang enhancement fails under the new, narrower definitions	Court accepted People’s concession and reversed the gang enhancement for failure to prove the newly required elements
Whether § 1109 (bifurcation of gang enhancements) applies retroactively	§ 1109 is not retroactive; no clear legislative intent to make it so	§ 1109 is ameliorative and intended to reduce prejudicial gang evidence; applies retroactively under Estrada line of cases	Court held § 1109 applies retroactively to cases not yet final
Whether denial of bifurcation under § 1109 was harmless or prejudicial	Even if § 1109 applied, the gang evidence was cross‑admissible on identity/motive so any error was harmless	Denial of bifurcation allowed inflammatory gang evidence about Nagata to prejudice Perez by guilt‑by‑association; evidence against Perez was weak	Applying Watson, court found a reasonable probability of a more favorable outcome absent the error; reversal and new trial ordered
