People v. Diaz CA5, F083790

Defendant Alexis Diaz posted advertisements online offering two minor girls for commercial sex, transported them to clients, and collected fees.
Charged in Fresno County with multiple counts including human trafficking, pimping, pandering, and dissuading a witness; ultimately pleaded no contest to human trafficking (added count 12 under § 236.1(a)) and dissuading a witness (§ 136.1(b)(2)).
Plea form set a 12-year ‘‘lid’’ (maximum) and the court advised she was likely eligible for probation; defendant later stated she understood the possible 12-year lid.
At sentencing the court denied probation and imposed the midterm 8 years on count 12 plus a consecutive 2 years on count 4 (total 10 years), with restitution and fines; defendant appealed.
Defendant did not obtain or request a certificate of probable cause under Penal Code § 1237.5 and limited her notice of appeal to post-plea sentencing matters; record shows a codefendant received probation.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether plea was voluntary/knowing and counsel misadvised re: probation	People: these claims attack plea validity and require a certificate of probable cause	Diaz: counsel misadvised she would get probation; she misunderstood the court and would withdraw plea	Court: Challenge to plea validity requires certificate under §1237.5; claim not reviewable here
Whether 10-year sentence is cruel/unusual or grossly disproportionate versus codefendant	People: sentencing challenge to a negotiated lid is in substance an attack on the plea and requires a certificate	Diaz: 10-year term is grossly disproportionate and violates state and federal cruel and unusual prohibitions	Court: Asserting the lid is unconstitutional attacks the plea; requires certificate and cannot be reached on appeal
Whether counsel was ineffective at sentencing (no memo, failed to argue low term §1170(b)(6) or codefendant disparity)	People: ineffective-assistance-at-sentencing claim does not require certificate but record must show deficient performance and prejudice	Diaz: counsel failed to file memo and press mitigating arguments, prejudicing outcome	Court: Claim not barred by certificate rule but appellate record is inadequate to show counsel had no tactical reason; claim better raised via habeas
