People v. Irving, 95 N.Y. 541 (1884)
A defendant who testifies in their own defense is subject to cross-examination on prior bad acts to impeach their credibility, even if those acts are similar to the crime for which they are being tried.
Summary
The defendant was convicted of assault with a dangerous weapon. On appeal, he argued that the trial court erred in allowing the prosecution to cross-examine him about prior altercations and assaults. The New York Court of Appeals affirmed the conviction, holding that a defendant who testifies in their own behalf is subject to the same cross-examination as any other witness, including questions about prior bad acts that may impair their credibility, even if those acts are similar to the charged crime. The extent of such cross-examination is within the trial court’s discretion.
Facts
The defendant was indicted for assault with a “knife, pistol, slung-shot, billy and club.” At trial, the defendant testified on his own behalf. During cross-examination, the prosecutor questioned him about other altercations and assaults he had been involved in previously.
Procedural History
The defendant was convicted in the trial court and sentenced to state prison. He moved for a new trial, which was denied. He then appealed to the Supreme Court, which affirmed the judgment. The defendant then appealed to the New York Court of Appeals.
Issue(s)
Whether the trial court erred in allowing the prosecution to cross-examine the defendant, who testified on his own behalf, about prior altercations and assaults.
Holding
No, because when a defendant chooses to testify, they subject themselves to the same rules of cross-examination as any other witness, including questioning about prior bad acts to impeach their credibility.
Court’s Reasoning
The Court of Appeals reasoned that when a defendant offers themselves as a witness, they take the risk of being questioned about their past conduct to impair their credibility. The court stated, “When a prisoner offers himself as a witness, in his own behalf, he is subject to the same rules upon cross-examination as any other witness. He may be asked questions disclosing his past life and conduct, and thus impairing his credibility. Such questions may tend to show that he has before been guilty of the same crime as that for which he is upon trial; but they are not on that account incompetent.” The court further noted that the extent of such cross-examination is largely within the discretion of the trial court. The court distinguished between introducing evidence of prior crimes as part of the prosecution’s case-in-chief, which is generally prohibited, and using such evidence to impeach the defendant’s credibility when they take the stand. By testifying, the defendant opens the door to inquiry into their character and prior conduct. The court acknowledged that such cross-examination could be prejudicial but emphasized that the defendant made the choice to testify and thus subjected themselves to this risk. The court cited previous cases, including Allen v. Bodine, Fralich v. People, and Real v. People, to support its conclusion that a witness’s credibility can be tested through questions about their past conduct.
