Background:
In 1977, Emmanuel Charles Whiteside was involved in a confrontation with a man named Calvin Love. What Whiteside claimed to be a drug related dispute escalated, and Whiteside stabbed Love to death. Whiteside was charged with second degree murder in Iowa. He claimed he acted out of self defense, as he believed Love was about to pull out a gun on him. Despite this, Whiteside admitted to his attorney that he had never actually seen a gun. Soon before taking the witness stand, he proposed changing his testimony, claiming to his lawyer he had seen “something metallic” in Love's hand, which he hoped would make his self defense claim more believable. Whiteside’s attorney believed this testimony was false and warned him he could not help present perjured testimony.
The Case:
Whiteside’s lawyer told him lawyers have an ethical duty not to knowingly present false evidence. The attorney warned Whiteside, if he lied under oath, he would have to inform the judge and could even withdraw from the case. Due to this warning, Whiteside decided not to testify that he saw “something metallic”. He instead testified consistently with his earlier statements, that he believed the victim had a gun, despite the fact he did not actually see one. The jury rejected his claim of self defense and found Whiteside guilty of second degree murder. After being convicted, Whiteside appealed, arguing his attorney's threats prevented him from giving the testimony he wanted, therefore violating his Sixth Amendment right to effective assistance of counsel. This case was eventually brought to the Supreme Court.
Debates From Each Side:
Whiteside’s argument consisted of the ideas, he had been denied his Sixth Amendment right to have effective legal representation, and that a criminal defendant has the right to testify in their own defense. He maintained, that by threatening to reveal a believed false testimony and withdraw from the case, Whiteside’s attorney pressured him into changing his testimony.
The State of Iowa, represented by Crispus Nix, warden of the Iowa State Penitentiary, stated lawyers are officers of the court and have an ethical duty that comes with their job to tell the truth. Due to this, attorneys can not knowingly present false testimony or help a client commit perjury. It was reminded that this function protects the integrity of the legal system, and since the Constitution does not protect lying under oath, the attorney acted properly and ethically.
Verdict:
In a unanimous 9-0 decision, the court ruled against Whiteside. It was held, an attorney does not provide ineffective assistance by refusing to help a client commit perjury. Lawyers have a legal and ethical obligation to prevent false testimony, and must act under truth. The Court maintained, the Sixth Amendment guarantees effective legal representation, not assistance in providing false evidence to the court. Whiteside's constitutional rights were found to have not been violated.
Legacy:
Nix v. Whiteside became an influential landmark case on legal ethics and the responsibilities of defense attorneys. This Supreme Court decision solidified, defense attorneys must not knowingly present false testimony, a lawyer's obligation to truth can outweigh a client's desire to testify falsely, and the Sixth Amendment does not include the right to commit perjury. It simultaneously maintained the idea that attorneys may warn clients about consequences of lying under oath without violating the Constitution. Today this case remains relevant representing accountability, integrity, and the balance of ethics and obligation. This precedent remains, and is often cited in cases debating attorney ethics of client advocacy and honesty in court, remaining influential even today.
