Background

  • Defendant William Joseph Cannon assaulted a 16-year-old (attempted rape) in 2010, pled to assault with intent to commit rape and related charges, and was sentenced to 7 years.
  • In 2016 the prosecutor filed an SVPA petition; probable cause found; multiple updated evaluations produced split expert opinions.
  • Defense counsel waived a jury trial at a 2018 pretrial conference while Cannon was absent; the bench trial occurred in October 2020.
  • Three experts testified: two State Hospital psychologists (Karlsson, Miculian) opined Cannon met SVP criteria (neurocognitive disorder from TBI, continued risk, ongoing pornography use, incomplete treatment); defense neuropsychologist (Dempsey) testified Cannon had improved and no longer posed the same volitional impairment.
  • Trial court found Cannon an SVP and committed him to Coalinga indefinitely (Dec. 15, 2020); Cannon appealed raising (1) insufficiency of evidence, (2) hearsay in expert testimony, and (3) equal protection for jury-advisement/personal-waiver protections.

Issues

Issue Plaintiff's Argument Defendant's Argument Held
Sufficiency of evidence that defendant is an SVP (likelihood to reoffend; necessity of custody) State: experts’ diagnoses, actuarial scores, ongoing porn use, incomplete treatment support a serious, well-founded risk and need for custodial treatment Cannon: prosecution failed to show current dangerousness/necessity to keep him in custody; defense expert showed substantial improvement Affirmed. Substantial evidence supports SVP finding and custodial necessity (court defers to trier of fact and prosecution experts).
Admissibility of case-specific hearsay in expert testimony (Sanchez claim) State: Dr. Karlsson properly relied on records and other evaluators as permitted by Evid. Code §§ 801–802 and SVPA evaluation rules; court limited any improper references Cannon: Dr. Karlsson relayed Dr. Dinishak’s neuropsych testing as true, violating Sanchez No reversible error. Trial court struck/ excluded case-specific portions; expert may base opinion on materials reasonably relied upon; presumption the court ignored inadmissible matters.
Equal protection — failure to advise defendant of jury right and obtain personal waiver State: SVPA does not require personal advisement/waiver; legislature intended court trial presumption; possible justifications (risk, judge neutrality) Cannon: similarly situated to MDO/NGI detainees who must be personally advised and waive; lack of personal advisement/waiver violates equal protection Remand required. Court conditionally affirmed commitment but remanded to allow Cannon to litigate equal protection claim; if violation found, vacate commitment and set jury trial unless valid personal waiver after advisement.
Harmlessness of alleged failure to advise/obtain personal waiver State: any procedural omission was harmless Cannon: record silent; waiver was entered by counsel while defendant absent, so harmlessness not shown Error (if any) not shown harmless on record; remand required for full adjudication of equal protection claim.
