Davis v. Washington, 547 U.S. 813 (2006), was a case decided by the Supreme Court of the United States and written by Justice Antonin Scalia that established the test used to determine whether a hearsay statement is "testimonial" for Confrontation Clause purposes. Two years prior to its publication, in Crawford v. Washington, the Supreme Court held that the Confrontation Clause bars “admission of testimonial statements of a witness who did not appear at trial unless he was unavailable to testify, and the defendant had had a prior opportunity for cross-examination.” The Supreme Court declined to define "testimonial" in Crawford which left lower courts without any guidance. However, in Davis v. Washington, along with Hammon v. Indiana which was consolidated with Davis, the Court clarified the meaning of "testimonial" and articulated a new standard.
