Hemphill v. New York
The Supreme Court ruled 8-1 that New York violated a murder defendant's Sixth Amendment right to confront witnesses against him by allowing the state to introduce a transcript of an unavailable witness's guilty plea — solely because the defendant's defense pointed to that witness as the real shooter.
The decision reaffirms that a judge's view that unconfronted out-of-court statements are needed to 'correct a misleading impression' is not a valid reason to bypass the constitutional guarantee that criminal defendants can cross-examine the witnesses used against them.
“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 statement of why New York's 'opening the door' rule cannot override the Sixth Amendment's confrontation guarantee.
How it got here: The New York trial court convicted Hemphill after admitting the plea transcript; both the Appellate Division and the New York Court of Appeals affirmed, and the Supreme Court agreed to hear the case.
The Case in Depth
What happened
In 2006, a stray 9-millimeter bullet killed a 2-year-old child in the Bronx. New York initially prosecuted Nicholas Morris for the murder, but later offered him a plea deal on a lesser, unrelated weapons charge. Years later, the state charged Darrell Hemphill with the murder after his DNA matched a blue sweater found at the scene. At trial, Hemphill blamed Morris. Because Morris was overseas and unavailable to testify, the state introduced a transcript of Morris's earlier guilty plea to counter Hemphill's defense — and the judge allowed it over Hemphill's objection, concluding Hemphill's arguments had "opened the door."
The question before the Court
Can a state court admit out-of-court statements from an unavailable witness against a criminal defendant — without any opportunity to cross-examine — simply because the defendant's defense theory made those statements relevant?
The Court's answer
No — New York's "opening the door" rule cannot override a criminal defendant's right to cross-examine the witnesses used against him. The Sixth Amendment's Confrontation Clause bars courts from admitting testimonial out-of-court statements from an unavailable witness unless the defendant had a prior chance to cross-examine that witness. No exception exists merely because a defendant's defense theory made those statements seem useful to correct a misleading impression in the jury's mind.
New York argued its rule was just a procedural limit on how defendants exercise the confrontation right, not a substantive exception to it. The Court rejected that framing: a rule that tells judges to weigh whether unconfronted testimony is necessary to set the record straight is exactly the kind of judicial reliability assessment that Crawford v. Washington (2004) forbade. Hemphill did not forfeit his confrontation right simply by arguing a defense that pointed to another person as the real shooter.

Why it matters
Criminal defendants across the country who mount aggressive third-party defenses — arguing that someone else committed the crime — cannot be penalized for doing so by having an opponent's unexamined out-of-court statements admitted to rebut them. Prosecutors and trial judges must find other constitutionally permissible tools, such as standard evidence-exclusion rules, to manage potentially misleading defense arguments.
What changes now
The case is sent back to the New York courts for further proceedings consistent with the Supreme Court's ruling. The Court declined to rule on whether the Confrontation Clause error was harmless — that question goes back to the state courts to assess in the first instance under state criminal law. New York's "opening the door" rule, as applied to allow unconfronted testimonial hearsay, can no longer be used to admit such evidence against defendants who mount third-party culpability defenses.
What this does not decide
The Court explicitly did not decide whether the common-law rule of completeness — which kicks in when a defendant actually introduces an unavailable declarant's own statements — could justify admitting related testimonial hearsay. It also did not rule on whether the constitutional error in this case was harmless, leaving that to the state courts on remand.
Concurrences and dissents
Concurrence — Justice Alito
Justice Alito agreed that admitting Morris's plea allocution violated the Confrontation Clause, but wrote separately to elaborate on when a defendant can implicitly waive the right to confront adverse witnesses. He argued that if a defendant actually introduces an unavailable witness's own out-of-court statements, the rule of completeness allows the opposing side to introduce the rest of those statements — because the defendant has made a knowing choice to put the declarant's words in play despite being unable to cross-examine. That scenario, Alito reasoned, is meaningfully different from Hemphill's case, where Hemphill only argued a defense theory without ever introducing any of Morris's statements.
Dissent — Justice Thomas
“I would dismiss this case for lack of jurisdiction under 28 U. S. C. §1257 because Hemphill did not raise his federal claim to the New York Court of Appeals.”Justice Thomas arguing the Court had no power to hear the case because Hemphill raised only a state-law argument below.
Justice Thomas would have dismissed the case for lack of jurisdiction. He argued that Hemphill never properly raised his Sixth Amendment claim before the New York Court of Appeals — only challenging the misapplication of New York's state-law door-opening doctrine, not its constitutionality. Thomas went further, arguing that the requirement to properly present a federal claim in state court is a hard jurisdictional limit on the Supreme Court's power to review state decisions, not a flexible prudential consideration. He criticized the Court for reaching a constitutional ruling without giving New York's courts a chance to clarify their own evidentiary rule in light of a concrete federal challenge.
How the Court got there
The legal reasoning, step by step
- The Sixth Amendment's Confrontation Clause guarantees every criminal defendant the right to cross-examine witnesses whose statements are used against them at trial. In Crawford v. Washington (2004), the Court locked in this protection by holding that so-called 'testimonial' out-of-court statements — like sworn statements made during court proceedings — can only be admitted against a defendant if the witness is unavailable AND the defendant had a prior chance to cross-examine. The Court in Crawford explicitly rejected the older approach, from Ohio v. Roberts (1980), that had let judges admit such statements whenever they seemed reliable enough.
- Morris's plea allocution — made in open court under oath — was testimonial under Crawford, and Hemphill never had any opportunity to cross-examine Morris. The only question was whether New York's 'opening the door' rule provided a valid basis to admit it anyway. Under that rule, drawn from People v. Reid, a trial judge could admit otherwise barred testimonial hearsay if a defendant's evidence or arguments created a 'misleading impression' that the hearsay was 'reasonably necessary to correct.'
- The Court held the Reid rule is not a mere procedural rule — it is a substantive evidentiary principle that decides what is admissible in a case. States may adopt reasonable procedural rules governing how defendants exercise the confrontation right (like timely-objection requirements), but New York's rule went further: it asked the trial judge to weigh the reliability and necessity of unconfronted testimony based on how misleading the defendant's defense seemed. That is precisely the kind of judicial reliability balancing Crawford forbids.
- The Court rejected New York's argument that the rule was necessary to protect the truth-finding function of courts. While protecting truth at trial is important, the Court has consistently declined to let that interest override constitutional rights. The cases New York cited — involving impeachment with evidence obtained through Fourth Amendment violations — involved prophylactic rules designed to deter constitutional violations, not exceptions to a constitutional guarantee itself. The Confrontation Clause's command is absolute: it 'admits no exception for cases in which the trial judge believes unconfronted testimonial hearsay might be reasonably necessary to correct a misleading impression.'
- The Court also noted that prosecutors are not left without tools when a defendant's defense seems one-sided. Standard evidentiary rules — including those permitting exclusion of evidence whose probative value is outweighed by unfair prejudice or potential to mislead the jury — remain available. The Court expressly left open whether the common-law rule of completeness (which applies when a defendant actually introduces the unavailable witness's own statements) might justify admitting related testimonial hearsay in a future case, since those circumstances were not present here.
Doctrinal impact
Cases affected by this decision
Reaffirms Crawford v. Washington (541 U. S. 36)
The Court relies on Crawford as the controlling rule, reaffirming its bar on admitting testimonial hearsay without prior cross-examination.
Distinguishes Ohio v. Roberts (448 U. S. 56)
New York's rule would effectively revive Roberts' rejected reliability approach; Crawford already abrogated that framework and the Court underscores it remains gone.
