Perry v. New Hampshire
The Supreme Court ruled that judges only need to screen an eyewitness identification for reliability before trial when police arranged the suggestive circumstances that led to it.
Because a bystander's identification of a man near a police officer happened by chance rather than through any police setup, the Court said the jury—not the judge—could weigh how much to trust it, leaving cross-examination and jury instructions to do that work instead.
How it got here: New Hampshire trial and supreme courts rejected Perry's due process challenge and upheld his conviction; the Supreme Court granted review to resolve a lower-court split.
The Case in Depth
What happened
Nubia Blandon called police after seeing a man breaking into her neighbor's car early one morning. When an officer asked her to point out the man, she looked out her window and identified Barion Perry, who happened to be standing in the parking lot next to another police officer at that moment. Perry was convicted of theft and later argued that admitting Blandon's identification without a prior judicial reliability check violated due process.
The question before the Court
If police did nothing to arrange or suggest an eyewitness identification, must a judge still screen it for reliability before letting the jury hear it?
Why it matters
Criminal defendants who face eyewitness identifications made under suggestive but not police-created circumstances—such as accidentally seeing a suspect handcuffed near police—won't get a pretrial judicial reliability hearing. Instead, they must rely on cross-examination, jury instructions, and evidence rules to challenge the identification in front of the jury, potentially making wrongful convictions from unreliable eyewitness testimony harder to prevent before trial.
What changes now
This is a final merits decision, not a temporary order. The New Hampshire Supreme Court's judgment affirming Perry's conviction stands, and no further proceedings on the identification issue are required. The ruling leaves in place the trial safeguards already used at Perry's trial—cross-examination, jury instructions, and rules of evidence—as the mechanism for challenging eyewitness identifications not arranged by police in future cases.
What this does not decide
The Court did not decide whether any due process check applies when there is no police action at all connected to an identification—Justice Sotomayor's dissent noted this gap. The ruling is limited to cases, like Perry's, involving some police presence but no police-arranged suggestive procedure, and does not address wholly private identifications.
Concurrences and dissents
Concurrence — Justice Thomas
Justice Thomas joined the majority in full but wrote separately to argue that the entire Stovall line of cases was wrongly decided because it rests on a 'substantive due process' theory of fundamental fairness that he believes has no basis in the Due Process Clause. He would limit those suggestive-identification precedents strictly to their own facts rather than extend them further.
Dissent — Justice Sotomayor
“By rendering protection contingent on improper police arrangement of the suggestive circumstances, the Court effectively grafts a mens rea inquiry onto our rule.”The dissent's core objection that the majority wrongly makes police intent decisive.
Justice Sotomayor argued the majority's police-arrangement requirement improperly grafts a mens rea-like inquiry onto due process doctrine, when the Court's real concern has always been the reliability-corrupting effect of suggestion regardless of whether police intentionally caused it. She contended the same two-step reliability inquiry should apply whether police created the suggestive circumstances intentionally or by accident, and would have vacated and remanded for the New Hampshire courts to actually assess reliability.
How the Court got there
The legal reasoning, step by step
- The Court explained that its prior eyewitness cases required suppression only when police used an identification procedure that was both suggestive and unnecessary—meaning the police themselves created the suggestive setup.
- Even when police create such suggestive circumstances, the Court's precedents don't call for automatic exclusion; instead judges assess under a 'totality of the circumstances' test whether the suggestion created a substantial likelihood the witness misidentified the wrong person.
- The Court reasoned that this due process check exists specifically to deter police from rigging identifications, so the rationale doesn't apply when no police misconduct caused the suggestive circumstances in the first place.
- The Court rejected extending the rule to all suggestive identifications regardless of police involvement, reasoning that nearly every eyewitness identification involves some element of suggestion, and expanding the rule would force judges to prescreen almost all eyewitness testimony.
- The Court concluded that when no improper police conduct produced the suggestive circumstances, existing trial safeguards—cross-examination, jury instructions on eyewitness fallibility, and rules of evidence—are sufficient to test reliability, so no separate pretrial judicial screening is constitutionally required.
