Hemphill v. New York
The Supreme Court ruled 8-1 that New York violated a murder defendant's constitutional right to confront witnesses by admitting a written plea transcript from the man he blamed for the crime, after deciding his defense had 'opened the door' to the evidence.
The decision reaffirms that judges cannot bypass the Sixth Amendment's confrontation requirement simply because they believe unchallenged out-of-court statements are needed to correct what looks like a misleading defense.
“The Confrontation Clause requires that the reliability and veracity of the evidence against a criminal defendant be tested by cross-examination, not determined by a trial court.”
The majority's core principle: judges cannot substitute their own reliability judgments for the constitutional guarantee of cross-examination.
How it got here: Convicted at trial, Hemphill lost appeals at both New York appellate levels before the Supreme Court agreed to hear the case.
The Case in Depth
What happened
In 2006, a stray bullet killed a 2-year-old child in the Bronx after a street fight. Police found 9-millimeter ammunition in the apartment of Nicholas Morris, who later pleaded guilty to possessing a different weapon — a .357 revolver — in exchange for the murder charges being dropped. Years later, Darrell Hemphill was charged with the murder after his DNA matched a blue sweater linked to the scene. At trial, he blamed Morris for the shooting and pointed to the 9-millimeter ammunition found in Morris's home.
The question before the Court
Can a court use a criminal defendant's decision to point blame at someone else as a reason to admit against him out-of-court statements he never had a chance to cross-examine?
The Court's answer
No — a court cannot use a defendant's decision to blame someone else for a crime as a reason to strip away his constitutional right to confront witnesses. New York's "opening the door" rule let the trial judge admit a transcript of the absent man's plea hearing to counter Hemphill's defense, even though that man was overseas and could not be cross-examined.
The Sixth Amendment's Confrontation Clause is not satisfied by a judge's assessment that unconfronted testimony is reliable enough or necessary enough to admit. The Constitution specifically requires that the reliability of evidence against a defendant be tested through cross-examination. Hemphill did not give up that right simply by mounting a defense that made the absent man's statement relevant — and no state rule that says otherwise can override an explicit constitutional guarantee.

Why it matters
Criminal defendants can point to this ruling when prosecutors try to introduce out-of-court statements — like plea transcripts from absent witnesses — by arguing the defense made those statements necessary. A judge's own view that the defense created a misleading impression is not enough; the Constitution requires cross-examination, not a judicial reliability call.
What changes now
The case is sent back to New York courts for further proceedings. The Court expressly left open one related question — whether the common-law rule of completeness, which allows a party to introduce the rest of a statement when the opposing side has put part of it in evidence, could ever justify admitting testimonial hearsay against a defendant. That question was not at issue here and remains for a future case. The Court also declined to rule on whether any constitutional error was harmless, deferring that assessment to the state courts on remand.
What this does not decide
The Court expressly did not decide whether the rule of completeness — allowing one side to introduce the remainder of a statement when the other side used part of it — could ever permit testimonial hearsay to be admitted against a criminal defendant. The harmless-error question was also left for the state courts on remand.
Concurrences and dissents
Concurrence — Justice Alito
Justice Alito agreed with the outcome but wrote separately to sketch when a defendant can be said to have impliedly waived the confrontation right through conduct. He argued that New York's door-opening rule doesn't qualify, because presenting misleading evidence doesn't signal any intent to waive confrontation. But he reasoned that the traditional rule of completeness does qualify as a valid implied waiver: when a defendant introduces part of an unavailable witness's statement, he has committed himself to what that witness says on the subject and cannot simultaneously object to the rest being admitted.
Dissent — Justice Thomas
Justice Thomas would have dismissed the case outright for lack of jurisdiction. In his view, Hemphill only argued in New York's highest court that the lower courts misapplied the state's own door-opening rule — he never properly raised a Sixth Amendment challenge. Thomas argued that the requirement to present a federal claim to the state courts is a binding jurisdictional limit, not a flexible prudential rule the Court can set aside, and that hearing the case without that foundation disrespected state courts and settled principles of federalism.
How the Court got there
The legal reasoning, step by step
- The Sixth Amendment's Confrontation Clause guarantees every criminal defendant the right 'to be confronted with the witnesses against him,' which the Court read in Crawford v. Washington (2004) to mean: out-of-court statements by unavailable witnesses — called testimonial hearsay — are admissible only if the defendant had a prior chance to cross-examine the speaker. Crawford threw out the older approach, from Ohio v. Roberts (1980), which had allowed such statements whenever a judge found them sufficiently reliable.
- Crawford's core holding is that the Constitution commands, not that evidence be reliable, but that reliability be assessed in a specific way — by testing it through cross-examination. Judges are not permitted to substitute their own reliability determinations for that constitutionally prescribed method, no matter how credible or incredible a statement may appear.
- New York's 'opening the door' rule, from People v. Reid, allowed a trial court to admit testimonial hearsay that would otherwise be barred if the defendant's own evidence or arguments created a 'misleading impression' and the hearsay was 'reasonably necessary' to correct it. New York argued this was a mere procedural rule about how defendants exercise confrontation rights, not a new exception to the Clause itself.
- The Court rejected that framing. The Reid rule is a substantive evidentiary principle that dictates what evidence is admissible — not a rule about procedural mechanics. Applying it requires a judge to weigh whether the defense presentation is misleading and whether the hearsay is necessary to correct it — precisely the kind of judge-made reliability balancing that Crawford forbade.
- The State argued truth-seeking values justify the rule, citing cases where courts permitted defendants to be impeached with otherwise-barred evidence. The Court distinguished those cases: each involved a prophylactic rule designed to deter violations of a constitutional right — not a direct exception to the constitutional right itself. No precedent permits courts to override a concrete constitutional guarantee in the name of fairness or accuracy.
- Because Morris's plea transcript was testimonial hearsay, and Hemphill never had any opportunity to cross-examine Morris, admitting it over Hemphill's objection — solely because the judge found the defense misleading — directly violated the Confrontation Clause.
