Whiteside was charged with murder in Iowa after stabbing a man during an altercation. Before trial, he told his lawyer he had not actually seen a gun in the victim’s hand but intended to testify that he saw something metallic because he believed that would strengthen a self-defense claim. Counsel warned Whiteside that he could not assist perjury and would disclose the false testimony to the court if necessary, while still continuing representation. Whiteside ultimately testified without claiming he saw a gun, was convicted, and later sought postconviction relief alleging ineffective assistance because counsel’s threats deprived him of effective advocacy.
Does a criminal defendant’s Sixth Amendment right to effective assistance of counsel entitle him to the assistance of counsel in presenting testimony the lawyer reasonably believes to be perjured?
The Sixth Amendment guarantees effective assistance of counsel, but it does not include a right to have counsel assist in presenting perjured testimony. An attorney’s duty of loyalty and advocacy is limited by the equally fundamental duty to avoid knowingly participating in fraud on the court.
No. Counsel’s refusal to cooperate with Whiteside’s proposed perjury, and counsel’s warning that he would disclose such perjury if necessary, did not constitute ineffective assistance of counsel under the Sixth Amendment.
The Court emphasized that there is no constitutional right to present false evidence and that preventing perjury serves the integrity of the judicial process. Because Whiteside’s lawyer acted consistently with ethical obligations and sought to deter false testimony rather than undermine a valid defense, his performance was not deficient under Strickland standards. The Court also rejected the claim of prejudice, reasoning that Whiteside was not deprived of any lawful defense or admissible truthful evidence. Advising a client not to commit perjury and threatening disclosure if the client insists is professionally proper, not ineffective.
Justice Blackmun concurred in the judgment but criticized the breadth of the Court’s discussion, arguing the case could be resolved more narrowly because counsel’s conduct caused no prejudice; Justices Brennan, Marshall, and Stevens joined that concurrence in part.
Nix v. Whiteside is a leading case on the intersection of the Sixth Amendment and lawyer ethics, establishing that effective assistance does not require counsel to aid client perjury. It is closely tied to Strickland v. Washington, 466 U.S. 668 (1984), for ineffective-assistance analysis, and reflects the principle that defendants have no right to present false evidence, consistent with Harris v. New York, 401 U.S. 222 (1971), and United States v. Havens, 446 U.S. 620 (1980). The case is frequently cited for the proposition that counsel may take reasonable steps to prevent perjury without violating the Constitution.
