Hemphill v. New York
The Supreme Court ruled 8-1 that New York violated Darrell Hemphill's Sixth Amendment right to confront witnesses when the trial court admitted an unavailable witness's plea transcript simply because his defense had made the evidence arguably relevant.
The decision reaffirms that trial judges cannot decide on their own that unconfronted, out-of-court testimony is reliable enough to use against a defendant — the Constitution's answer to that question is always cross-examination, not a judicial reliability judgment.
“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 judge-driven reliability approach is unconstitutional.
How it got here: A New York trial court convicted Hemphill of murder; the Appellate Division affirmed; the New York Court of Appeals affirmed; the Supreme Court agreed to hear the case.
The Case in Depth
What happened
In 2006, a 2-year-old child was killed by a stray 9-millimeter bullet during a street fight in the Bronx. New York originally charged Nicholas Morris with the murder, but later let him plead guilty to possessing a different firearm — a .357 revolver — that had not been used in the killing. Years later, DNA evidence linked Darrell Hemphill to a blue sweater the shooter was seen wearing, and he was charged with the murder. At trial, Hemphill pointed the finger at Morris, arguing the 9-millimeter ammunition found in Morris's apartment proved Morris was the shooter. Morris was abroad and unavailable to testify.
The question before the Court
Did a New York court violate a murder defendant's constitutional right to confront the witnesses against him by admitting, over his objection, an unavailable witness's guilty plea transcript at trial because his own defense had "opened the door" to it?
The Court's answer
No. The Court held that New York's "open the door" rule — which allowed the trial court to read Morris's plea transcript to the jury because Hemphill's defense had created a "misleading impression" — violated the Sixth Amendment's Confrontation Clause. Under the Clause, a defendant has the right to cross-examine the witnesses used against him. The Court's 2004 decision in Crawford v. Washington established that this right cannot be overridden simply because a judge believes an out-of-court statement is reliable or necessary to set the record straight.
The Court rejected New York's argument that its rule was merely a procedural regulation of how the confrontation right is exercised, not a substantive exception to it. Requiring a judge to weigh whether unconfronted testimony was "reasonably necessary to correct a misleading impression" is precisely the kind of reliability-weighing that Crawford forbade. Hemphill did not forfeit his confrontation right simply by presenting a defense that made Morris's plea allocution arguably relevant to rebut it.

Why it matters
Criminal defendants nationwide retain their right to cross-examine the evidence used against them, even when their defense strategy makes unconfronted out-of-court statements relevant. Prosecutors who relied on "open the door" doctrines to admit otherwise barred testimony will need to use other tools — standard hearsay rules and the judge's power to exclude unfairly prejudicial evidence — instead.
What changes now
The New York Court of Appeals' decision affirming Hemphill's conviction is reversed, and the case is sent back to New York courts for further proceedings. On remand, the state courts will have the first opportunity to assess whether the constitutional error was harmless — meaning whether the result would have been the same without the improperly admitted plea transcript. The Supreme Court declined to decide that question itself, following its usual practice of deferring that assessment to state courts in the first instance.
What this does not decide
The Court explicitly left open whether the common-law rule of completeness — which allows a party to introduce the rest of a statement when the other side introduced part of it — could ever justify admitting an unavailable person's testimony against a criminal defendant. The harmless-error question was also expressly reserved for the state courts on remand.
Concurrences and dissents
Concurrence — Justice Alito
Justice Alito agreed that Morris's plea transcript was improperly admitted, but wrote separately to explore when a defendant can impliedly waive the confrontation right through conduct. He argued that introducing misleading evidence does not, by itself, signal any intention to give up the right to cross-examine a particular witness — so the New York rule fails. But he emphasized that the traditional rule of completeness can support implied waiver: when a defendant introduces part of an unavailable person's own statement, he has effectively chosen to let that person speak without cross-examination and cannot object to the rest of the statement being admitted.
Dissent — Justice Thomas
Justice Thomas would have dismissed the case for lack of jurisdiction. He argued that Hemphill never actually raised a Sixth Amendment claim in the New York Court of Appeals — he only challenged whether state courts misapplied New York's own door-opening doctrine — so there was no federal question properly before the Supreme Court. Thomas also argued that the requirement to present a federal claim to the state court is a firm jurisdictional limit on the Court's power to review state decisions, not a flexible prudential consideration the Court can set aside when convenient.
How the Court got there
The legal reasoning, step by step
- The Sixth Amendment's Confrontation Clause gives every criminal defendant the right to cross-examine the witnesses used against him at trial. In Crawford v. Washington (2004), the Court ruled that 'testimonial' out-of-court statements — including sworn guilty plea transcripts — may not be used against a defendant unless the person who made them is unavailable AND the defendant previously had a chance to cross-examine that person.
- Crawford also rejected an earlier, more flexible approach from Ohio v. Roberts (1980) that had allowed unconfronted statements when a judge found them sufficiently reliable. Crawford held that the Constitution does not command that evidence merely be reliable; it commands that reliability be tested through cross-examination. Courts cannot create new exceptions to the confrontation right beyond those that existed at the founding.
- New York argued its 'open the door' rule was not a confrontation exception at all but only a procedural regulation — the theory being that Hemphill, by presenting misleading evidence, signaled he no longer needed cross-examination to protect him. The Court rejected this framing. The rule is a substantive evidentiary principle dictating what evidence is relevant and admissible — not a rule about the manner of asserting a procedural right.
- Under New York's rule, a judge must determine whether a defendant's argument created a 'misleading impression' requiring correction with unconfronted testimony. That is exactly the reliability-weighing Crawford forbade. Whether Hemphill's theory about Morris was credible or misleading was not for the trial judge to assess; the Constitution assigns that task to cross-examination, not judicial gatekeeping.
- The State argued that allowing defendants to present misleading defenses without consequence undermines the truth-finding function of trials, citing cases permitting impeachment with otherwise excluded evidence. The Court distinguished those cases: each involved a judge-made prophylactic rule designed to deter a constitutional violation that had already happened — not the constitutional guarantee itself. The Confrontation Clause is a direct constitutional command, not a deterrent measure subject to balancing.
- The Court noted that other well-established tools remain available to prevent defendants from misleading juries — general hearsay rules, the power to exclude unfairly prejudicial evidence under rules like Federal Rule of Evidence 403, and limiting instructions — so reversing did not leave prosecutors without recourse.
