Hemphill v. New York

No. 20-637 SCOTUS · Decided Decided SCOTUS
Argued: Oct 5, 2021 Decided: Jan 24, 2022


The Facts

Darrell Hemphill was tried in New York for murder after a 9mm bullet killed a bystander. Hemphill introduced evidence suggesting that Nicholas Morris, who had pled guilty to possessing a 9mm weapon, fired the fatal shot. The prosecution responded by introducing Morris's plea allocution under New York's curative admissibility doctrine without calling Morris to testify. Hemphill was convicted of murder. The New York courts held that Hemphill had forfeited his right to confront Morris by opening the door.

The Issue

Whether the Confrontation Clause permits admission of otherwise inadmissible hearsay when a defendant 'opens the door' through trial strategy

The Rules

Sixth Amendment Confrontation Clause

Crawford v. Washington testimonial hearsay standard

State evidentiary 'opening the door' doctrine vs. constitutional limits

The Application

History

When Hemphill introduced evidence suggesting Morris fired the fatal shot, he did not forfeit his right to confront Morris through New York's curative admissibility doctrine. Although the prosecution sought to rebut the misleading impression created by Hemphill's defense, that Morris, not Hemphill, was the killer, it could not do so by introducing Morris's testimonial plea allocution without producing Morris for cross-examination. The Confrontation Clause protects a defendant's ability to test the reliability of evidence used against him, and a defendant's trial strategy of challenging the prosecution's theory does not condition or diminish this right. New York's curative admissibility doctrine, designed to level the playing field when a defendant opens a door, cannot be used to circumvent the Sixth Amendment's core guarantee.

The Conclusion

**Reversed 8-1.** Hemphill's Confrontation Clause rights were violated when Morris's plea allocution was admitted without Morris being available for cross-examination. New York's curative admissibility doctrine cannot override the federal constitutional guarantee. Thomas dissented.

Case Analysis

Overview

The Supreme Court held 8-1 that New York's curative admissibility doctrine cannot override the Confrontation Clause, and a defendant's trial strategy does not forfeit the right to confront witnesses when the prosecution introduces testimonial hearsay in response.

Facts

Darrell Hemphill was tried in New York for murder after a 9mm bullet killed a bystander. Hemphill introduced evidence suggesting that Nicholas Morris, who had pled guilty to possessing a 9mm weapon, fired the fatal shot. The prosecution responded by introducing Morris's plea allocution under New York's curative admissibility doctrine without calling Morris to testify. Hemphill was convicted of murder. The New York courts held that Hemphill had forfeited his right to confront Morris by opening the door.

Issue

Whether New York's curative admissibility doctrine, which allows the prosecution to introduce otherwise inadmissible evidence to rebut a misleading impression created by the defense, overrides the Sixth Amendment's Confrontation Clause.

Rule

The Confrontation Clause guarantees a criminal defendant the right to confront the witnesses against him. A defendant's decision to introduce evidence does not forfeit this right when the prosecution responds with testimonial hearsay. The state cannot condition the use of the Confrontation Clause on the defendant's agreement not to challenge the prosecution's theory, and curative admissibility doctrines cannot authorize what the Clause forbids.

Analysis

When Hemphill introduced evidence suggesting Morris fired the fatal shot, he did not forfeit his right to confront Morris through New York's curative admissibility doctrine. Although the prosecution sought to rebut the misleading impression created by Hemphill's defense, that Morris, not Hemphill, was the killer, it could not do so by introducing Morris's testimonial plea allocution without producing Morris for cross-examination. The Confrontation Clause protects a defendant's ability to test the reliability of evidence used against him, and a defendant's trial strategy of challenging the prosecution's theory does not condition or diminish this right. New York's curative admissibility doctrine, designed to level the playing field when a defendant opens a door, cannot be used to circumvent the Sixth Amendment's core guarantee.

Conclusion

**Reversed 8-1.** Hemphill's Confrontation Clause rights were violated when Morris's plea allocution was admitted without Morris being available for cross-examination. New York's curative admissibility doctrine cannot override the federal constitutional guarantee. Thomas dissented.
