Delaware v. Van Arsdall

Justice Rehnquist delivered the opinion of the Court.

Respondent Robert Van Arsdall was convicted of murder in a Delaware trial court. The Supreme Court of Delaware reversed his conviction on the ground that the trial court, by improperly restricting defense counsel’s cross-examination designed to show bias on the part of a prosecution witness, had violated respondent’s confrontation rights under the Sixth and Fourteenth Amendments to the United States Constitution, and that such violation required automatic reversal. 486 A. 2d 1 (1984). While we agree that the trial court’s ruling was contrary to the mandate of the Confrontation Clause of the Sixth Amendment, we conclude that the Supreme Court of Delaware was wrong when it declined to consider whether that ruling was harmless in the context of the trial as a whole.

Shortly after midnight on January 1, 1982, Doris Epps was stabbed to death in an apartment in Smyrna, Delaware, after an all-day New Year’s Eve party. Respondent and Daniel Pregent, who by respondent’s testimony were the only two people in the apartment with Epps at the time she was killed, were arrested at the scene of the crime and charged with Epps’ murder. At separate trials, respondent was convicted and Pregent was acquitted.
