907 F.3d 1212
9th Cir.2018Background
- In June 2001 Maquiz robbed a man at a Perris pay phone alone, concealing his face and fleeing; police arrested him minutes later and recovered a handgun and ammunition.
- At a 2002 California jury trial Maquiz was convicted of three robberies (one from 2001 committed alone; two from 1999 committed with others), plus weapons and ID offenses.
- The prosecution sought gang sentencing enhancements under Cal. Penal Code § 186.22(b)(1); the jury found the 2001 robbery enhancement (10 years) true.
- The only evidence linking the 2001 robbery to the Perres Mara Villa (PMV) gang was testimony from Deputy Brewer, a law‑enforcement gang expert, who opined that solo crimes can benefit a gang by generating fear/respect and that proceeds may be shared.
- Maquiz sought habeas relief challenging admissibility of the expert’s ultimate‑issue opinion and insufficiency of evidence for the 2001 gang enhancement; the Ninth Circuit held expert testimony did not violate due process but that the expert’s conclusory testimony alone was insufficient under Jackson to support the gang enhancement and reversed for resentencing.
Issues
| Issue | Plaintiff's Argument (Maquiz) | Defendant's Argument (State) | Held |
|---|---|---|---|
| Admissibility of gang‑expert opinion on whether the 2001 robbery "benefitted" the gang | Deputy Brewer’s opinion that the robbery benefitted PMV was effectively an opinion on the ultimate issue and denied due process | Expert testimony about gang practices and effects is permissible; no clearly established Supreme Court rule forbids ultimate‑issue expert testimony | Admission of expert’s opinion did not violate due process; no clearly established Supreme Court precedent bars such testimony |
| Sufficiency of evidence for gang enhancement ("gang‑related" prong) | Expert’s testimony alone was conclusory and lacked record facts tying the 2001 robbery to gang territory, gang signs, communication with members, or sharing of proceeds | Expert’s experience with PMV, testimony that PMV engages in robberies, graffiti near the robbery site, and explanation how solo acts can benefit a gang were sufficient for a rational juror | Reversed: under Jackson (as applied under AEDPA) no rational trier of fact could find the gang‑related element proved beyond a reasonable doubt based solely on the expert’s conclusory testimony |
| Sufficiency of evidence for gang enhancement (specific‑intent prong) | No evidence Maquiz intended to promote or assist gang criminal conduct; he concealed identity and there was no proof of intent to further PMV | Expert’s explanation that members act to further gang objectives and may share proceeds supports an inference of specific intent | Reversed as to specific intent too; expert testimony alone insufficient to prove intent beyond a reasonable doubt |
| Remedy | Vacate gang enhancement for 2001 robbery and remand for resentencing | Uphold enhancement; deny habeas | Grant habeas relief as to the 2001 gang enhancement; remand for resentencing without that enhancement |
