People v. Walker, 83 N.Y.2d 457 (1994)
A defendant’s prior use of aliases is generally admissible as evidence of dishonesty bearing on credibility, and the trial court has discretion to allow cross-examination on such matters unless the probative value is substantially outweighed by the risk of undue prejudice.
Summary
The case concerns whether the prosecution could cross-examine the defendant about his prior use of aliases. The defendant was convicted of criminal sale of a controlled substance. Prior to trial, a Sandoval hearing addressed the admissibility of the defendant’s prior convictions and use of aliases. The defense argued that some aliases had innocent explanations. The trial court allowed questioning about the aliases, and the defendant did not testify. The Court of Appeals held that a defendant’s prior use of aliases is an indication of dishonesty and is relevant to credibility. The court affirmed the trial court’s decision, finding no abuse of discretion.
Facts
The defendant was charged with selling cocaine to an undercover officer on November 20, 1990. Prior to trial, the prosecution sought to cross-examine the defendant on two prior felony convictions, 17 misdemeanor convictions, and the use of 14 different names and 5 different dates of birth when arrested. The defense argued that the use of some aliases had innocent explanations, such as religious reasons or being under the influence of drugs.
Procedural History
The trial court ruled that the prosecution could question the defendant about his use of aliases and the number and dates of prior convictions but not the underlying facts. The defendant did not testify and was convicted of criminal sale in the third degree. The Appellate Division affirmed the conviction. The Court of Appeals granted leave to appeal.
Issue(s)
Whether the trial court erred in allowing the prosecution to cross-examine the defendant about his prior use of aliases, despite the defense’s claim of alternative explanations for their use.
Holding
No, because a defendant’s prior use of aliases is an indication of dishonesty that goes to the heart of the question of that individual’s testimonial credibility, and the trial court did not abuse its discretion in allowing cross-examination on the matter.
Court’s Reasoning
The Court of Appeals reasoned that impeachment aims to discredit a witness and demonstrate untruthfulness. Prior immoral, vicious, or criminal conduct is relevant to credibility. Using a false name is an act of prevarication, suggesting a willingness to put self-interest ahead of principle. While some alias use may have innocent explanations, this does not require a special rule for alias evidence. The trier of fact can weigh the evidence and resolve credibility issues. The court emphasized that the trial court has broad discretion over the scope of cross-examination. Unlike prior crime evidence, alias evidence carries no implication other than untruthfulness. The court stated, “Manifestly, a suspect’s use of a false name or other inaccurate pedigree information is an indication of dishonesty that goes to the very heart of the question of that individual’s testimonial credibility.” The court concluded that defense counsel’s assertions about innocent explanations were speculative and did not suggest a legal reason to mandate preclusion. The court affirmed the Appellate Division’s order.
