Summary: written with AI from the case record.
What it's about
The Supreme Court agreed with New Hampshire and upheld the state court’s ruling: judges need not screen reliability unless law enforcement arranged unnecessarily suggestive circumstances.
The case concerned the use of eyewitness identification evidence in a criminal trial.
Question presented
Do the Due Process protections against unreliable identification evidence apply to all identifications made under suggestive circumstances?
What the Court decided
Holding
The Due Process Clause does not require a preliminary judicial inquiry into the reliability of an eyewitness identification when the identification was not procured under unnecessarily suggestive circumstances arranged by law enforcement. Affirmed.
- Result
- Affirmed
The Court's reasoning
The Court limited this preliminary review to eyewitness identifications obtained under unnecessarily suggestive circumstances arranged by law enforcement. Because Perry's identification fell outside that category, the Court said due process did not require a preliminary reliability review.
The vote
From the opinions
“Our due process concern, however, arises not from the act of suggestion, but rather from the corrosive effects of suggestion on the reliability of the resulting identification.”
What's next
The New Hampshire Supreme Court's ruling remains in place for Perry. Lower courts must apply the Supreme Court's rule when deciding whether due process requires a preliminary reliability review.
