People v. Paperno, 54 N.Y.2d 294 (1981)
A prosecutor’s participation in pre-trial proceedings does not automatically disqualify them from acting as the trial prosecutor, unless their prior involvement creates a substantial risk of prejudice to the defendant.
Summary
The defendant was convicted of murder, robbery, and burglary. He appealed, arguing that the prosecutor’s actions made him an “unsworn witness” against the defendant, violating his due process rights. The Court of Appeals affirmed the conviction, holding that the trial court did not abuse its discretion in denying a mistrial. The court reasoned that the defendant failed to demonstrate a substantial likelihood of prejudice from the prosecutor’s limited references to his pretrial involvement, especially since the voluntariness of the confession primarily concerned the detective’s actions, not the prosecutor’s. Furthermore, the defense failed to object to the specific instances during trial that they now claim prejudiced the defendant.
Facts
Three individuals were murdered in their apartment during a robbery in December 1977. The defendant was arrested six months later and, after being Mirandized, initially denied involvement. He later confessed to a homicide detective, admitting his participation in the robbery but claiming an accomplice shot the victims. Assistant District Attorney Cooper and a stenographer then recorded a second, similar confession with additional details.
Procedural History
The defendant’s motion to suppress the confessions was denied. An initial trial ended in a mistrial due to jurors seeing inadmissible information. At the retrial, during jury selection, ADA Cooper mentioned his role in taking the defendant’s second confession. The defense moved for a mistrial, arguing this made Cooper an unsworn witness. The court denied the mistrial but pledged to minimize Cooper’s pretrial involvement references. The Appellate Division affirmed the convictions without opinion, leading to this appeal to the Court of Appeals.
Issue(s)
Whether the prosecutor’s disclosure to the jury that he had taken the defendant’s confession, and subsequent limited references to that fact during the trial, deprived the defendant of due process and the right to confront witnesses, effectively making the prosecutor an unsworn witness against him?
Holding
No, because the defendant did not demonstrate a substantial likelihood of prejudice resulting from the prosecutor’s references to his pretrial involvement. The trial court, therefore, did not abuse its discretion in denying the motion for a mistrial.
Court’s Reasoning
The Court of Appeals applied the principles articulated in the companion case, People v. Paperno. The court emphasized that granting or denying a mistrial is within the trial court’s discretion, reversible only for abuse. Here, it was not shown the prosecutor would testify or that his conduct was a material issue. The defense focused on coercion related to the first confession (by the detective), not the second (by the prosecutor). Crucially, the defendant did not show a substantial likelihood of prejudice. “The prosecutor’s pretrial conduct never became, in actuality, an issue at the trial.” While avoiding mention of the prosecutor’s role would have been preferable, the lack of demonstrated prejudice did not warrant reversal. The court also noted the lack of contemporaneous objections, which supported the view that the prosecutor’s actions were not a material issue. The Court suggested, “It might have been preferable for the court to have ordered that those parts of defendant’s confession identifying the prosecutor be redacted. Nevertheless, under the circumstances of this case, we conclude that the court’s failure to do so did not deprive defendant of a fair trial.”
