Angel Lopez-Valenzuela v. County of Maricopa
719 F.3d 1054
9th Cir.
2013
Read the full case

Background

  • In 2006 Arizona voters adopted Proposition 100 (Amend. to Ariz. Const. art. II, §22(A)(4)), barring bail for "serious felony offenses" where the arrestee has "entered or remained in the United States illegally" and "proof is evident or presumption great."
  • Arizona Legislature defined "serious felony offense" (Class 1–4 felonies and certain aggravated DUI) in A.R.S. §13‑3961(A)(5)(b); procedural rules set initial‑appearance (IA) procedures and a probable cause standard for immigration status determinations.
  • After implementation confusion, Arizona adopted rules (and gave availability of a Simpson/Segura evidentiary hearing) where IA uses probable cause to trigger detention and a later hearing may apply the higher "proof evident/presumption great" standard.
  • Plaintiffs Lopez‑Valenzuela and Castro‑Armenta (class) challenged Proposition 100 and implementing statutes/rules asserting violations of substantive and procedural due process (Fourteenth), the Eighth Amendment Excessive Bail Clause, the Sixth Amendment right to counsel at critical stages, and federal preemption by immigration law; district court granted summary judgment for defendants on most claims.
  • The Ninth Circuit affirmed: it held Proposition 100 serves a legitimate regulatory purpose (preventing flight), is not excessive under Salerno, the probable cause standard and available Simpson/Segura hearings satisfy procedural due process, it does not violate the Eighth Amendment, does not create a Sixth Amendment right to counsel at IA, and is not preempted by federal immigration law.

Issues

Issue Plaintiff's Argument Defendant's Argument Held
Substantive due process — punitive intent / excessiveness under Salerno Proposition 100 is punitive (motivated to punish undocumented immigrants) and excessive because it imposes categorical, irrebuttable detention Law is regulatory: compelling interest in preventing flight; reasonably related to that goal; extension of existing categorical no‑bail practices Rejected plaintiff: record does not show punitive intent; law is reasonably related to preventing flight and not excessive under Salerno
Procedural due process — standard and procedures for status determinations Probable cause is inadequate for complex immigration‑status determinations; IA procedures (deputy notes, lack of disclosure, and failure to notify right to hearing) are unfair Probable cause at IA is adequate; Simpson/Segura hearings and Rule 7.4(b) (hearing within 7 days) cure IA limitations; federal law limits disclosure of DHS documents Rejected plaintiff: probable cause standard and subsequent evidentiary hearings provide constitutionally adequate process
Eighth Amendment — excessive bail Categorical denial of bail based solely on immigration status is arbitrary and violates Excessive Bail Clause Eighth Amendment doesn't guarantee bail in all cases; bail denial here serves valid state interests to secure presence for trial Rejected plaintiff: denial is not "excessive" given state's legitimate interest in preventing flight
Sixth Amendment — right to counsel at initial appearance IAs with status determinations are critical stages requiring counsel because they can determine substantive liberty (detention) IA is administrative (no plea), counsel is not constitutionally required at IA; counsel will be appointed thereafter and Simpson/Segura hearings are available Rejected plaintiff: IA is not a critical stage triggering Sixth Amendment right to counsel
Federal preemption (immigration) Proposition 100 impermissibly regulates immigration, creates state immigration classifications, conflicts with INA/detention/removal framework State law regulates pretrial detention for state crimes and relies on federal information/ICE holds; it does not displace federal immigration enforcement or set immigration policy Rejected plaintiff: law is not field‑preempted or conflict‑preempted and does not operate as a regulation of immigration contrary to federal law
