Pretrial Identifications, the Eighth Amendment, and Trial Rights
Key Takeaways
- A pretrial identification violates due process if the procedure was unnecessarily suggestive AND created a substantial likelihood of misidentification (Neil v. Biggers reliability factors); the remedy is exclusion of the tainted identification but an in-court ID may survive on an independent source.
- The Sixth Amendment right to counsel applies to POST-charge lineups and showups (Wade-Gilbert) but not to pre-charge identifications or to photographic arrays at any stage (Ash).
- The Eighth Amendment bars cruel and unusual punishment: the death penalty must be limited to murder with aggravating circumstances found by a jury, may not be imposed on the intellectually disabled (Atkins) or for crimes committed as a juvenile (Roper), and grossly disproportionate non-capital sentences are rare violations.
- The prosecution must prove every element beyond a reasonable doubt (In re Winship), and Brady v. Maryland requires disclosure of material exculpatory and impeachment evidence; suppression of such evidence violates due process.
- A guilty plea must be voluntary and intelligent, entered with knowledge of the charge, the rights waived, and the consequences (Boykin); the right to a unanimous jury verdict now applies to the states (Ramos).
Identification procedures are attacked on two distinct grounds. First, due process: an identification obtained through a procedure that was unnecessarily (impermissibly) suggestive and that created a substantial likelihood of irreparable misidentification is inadmissible. Courts apply the Neil v. Biggers reliability factors — the witness's opportunity to view the perpetrator, the degree of attention, the accuracy of any prior description, the witness's level of certainty, and the time between the crime and the identification — to decide whether, despite suggestiveness, the identification was nonetheless reliable.
Manson v. Brathwaite confirms reliability is the linchpin. A one-person 'showup' is suggestive but may be justified by exigency (e.g., a quick field identification near the crime scene). Second, the Sixth Amendment right to counsel applies to post-charge corporeal identifications — lineups and showups conducted after the initiation of formal proceedings (United States v. Wade; Gilbert v. California) — so an uncounseled post-charge lineup is excluded. But this counsel right does NOT extend to pre-charge lineups (Kirby v. Illinois) or to photographic arrays at any stage, because the defendant is not present (United States v. Ash).
Even where a pretrial identification is suppressed, the witness may make an in-court identification if the prosecution shows by clear and convincing evidence an independent source for it — the witness's untainted memory of the crime itself.
The Eighth Amendment prohibits cruel and unusual punishments. In the capital context, the death penalty is permissible only for murder (Coker barred it for rape of an adult, and Kennedy v. Louisiana barred it for child rape where no death resulted), and the sentencing scheme must guide discretion: the jury must find at least one statutory aggravating circumstance and must be permitted to consider all relevant mitigating evidence. Categorical exemptions bar execution of the intellectually disabled (Atkins v. Virginia), the insane (Ford v. Wainwright), and those who committed their crimes while under 18 (Roper v. Simmons).
The jury — not the judge — must find the facts (aggravators) that make a defendant eligible for death (Ring v. Arizona). For juveniles, the Court has barred life without parole for non-homicide offenses (Graham v. Florida) and barred mandatory life without parole for juvenile homicide offenders (Miller v. Alabama). Outside the capital and juvenile contexts, the proportionality principle exists but is extremely deferential: the Court has upheld long recidivist sentences (Ewing v. California upheld a 25-to-life Three Strikes sentence) and finds gross disproportionality only in the rarest cases.
California's Three Strikes law, reformed by Proposition 36 in 2012 to generally require that the third strike be a serious or violent felony, is a useful state-law reference point.
Several due process guarantees secure a fair adjudication. In re Winship holds that the Due Process Clause requires the prosecution to prove every element of the charged offense beyond a reasonable doubt; the burden of persuasion on an element may not be shifted to the defendant, though the state may place the burden of proving an affirmative defense on the defendant.
Brady v. Maryland requires the prosecution to disclose to the defense all material evidence favorable to the accused — both exculpatory evidence and impeachment evidence (Giglio) — and suppression of such evidence violates due process where there is a reasonable probability the result would have been different. A guilty plea is a waiver of the rights to trial, to confront witnesses, and against self-incrimination, so it must be voluntary and intelligent; under Boykin v. Alabama the record must affirmatively show the defendant understood the nature of the charge, the rights being waived, and the maximum penalty.
Plea bargains are enforced under contract principles, and Padilla v. Kentucky requires counsel to advise a noncitizen defendant of the deportation consequences of a plea. Finally, recall the structural trial rights drawn together across this chapter: the right to a unanimous jury verdict now binds the states (Ramos v. Louisiana), the right to a public and speedy trial, the right to compulsory process, and the presumption of innocence — together forming the constitutional architecture of a fair criminal trial.
Several pretrial and structural guarantees round out the chapter and frequently appear as cross-cutting essay issues. A defendant must be competent to stand trial — possessing a rational and factual understanding of the proceedings and the present ability to consult with counsel (Dusky v. United States) — which is a present-time inquiry wholly distinct from the insanity defense (a past-time inquiry into mental state at the moment of the crime); the state may not try or sentence an incompetent defendant and may, within limits, involuntarily medicate to restore competency (Sell v. United States).
Pretrial process protections include the right to a probable-cause determination promptly after a warrantless arrest (Gerstein; County of Riverside requires it generally within 48 hours), the right to bail that is not excessive under the Eighth Amendment (though there is no absolute right to bail in capital or dangerous cases), and grand-jury indictment in federal felony cases (a right NOT incorporated against the states, so California may and does proceed by information after a preliminary hearing).
On identifications, recall the analytical sequence: first ask whether the Sixth Amendment counsel right applied (post-charge corporeal lineups only, never photo arrays), then test the procedure for due-process suggestiveness under the Biggers reliability factors, and finally — even if a pretrial identification is suppressed — allow an in-court identification supported by an independent source shown by clear and convincing evidence.
The Eighth Amendment's evolving 'evolving standards of decency' framework drives its categorical death-penalty and juvenile-sentencing rules; Montgomery v. Louisiana made Miller's bar on mandatory juvenile life-without-parole retroactive, and Jones v. Mississippi clarified that no separate finding of permanent incorrigibility is required before imposing a discretionary juvenile LWOP.
California layers on its own sentencing reforms a candidate should know: Proposition 36 (2012) reformed the Three Strikes law so that a third strike generally must itself be a serious or violent felony for the indeterminate life term to apply; Proposition 57 (2016) expanded parole consideration for nonviolent offenders and required a judicial 'transfer hearing' before a juvenile may be tried as an adult, ending direct-file by prosecutors; and the racial-justice and sentencing-reform statutes have further constrained enhancements.
Work a synthesis hypothetical: police arrest D without a warrant, hold him 60 hours before any judicial probable-cause determination, conduct a suggestive one-person showup at the scene, and later the prosecution fails to disclose an eyewitness's contradictory statement. This single fact pattern implicates a Riverside violation (delay beyond 48 hours presumptively unreasonable), a due-process identification challenge under Biggers, and a Brady disclosure violation — illustrating how trial-fairness issues stack.
The disciplined essay approach for this closing material: identify each discrete guarantee (competency, probable-cause hearing, bail, identification due process, Brady, jury and verdict rules, Eighth Amendment limits), apply its specific standard, and note the California statutory or initiative overlay (Propositions 36 and 57, information charging, section 1382 timing) wherever it diverges from or supplements the federal constitutional floor.
Together these doctrines, with the substantive crimes and defenses earlier in the chapter, supply the full toolkit for both the MBE criminal-procedure questions and the California-specific criminal-law and procedure essays.

Before any charges are filed, police show a robbery witness a single photograph of the suspect and ask, 'Is this the man who robbed you?' The witness says yes. The defendant later argues his Sixth Amendment right to counsel was violated at this identification. Is he correct?
After a conviction, the defense learns the prosecution had, before trial, possessed a witness statement strongly suggesting another person committed the crime, and never disclosed it. There is a reasonable probability the outcome would have differed. What is the most accurate characterization?
