One of the hallmarks of our criminal justice system that evidence of prior criminal conduct is not permitted to show a persons propensity or tendency to commit crimes. Except in very limited circumstances evidence of prior criminal conduct is not permitted on the prosecutions direct case. However, if a defendant chooses to testify the Court is required to hold a pre-trial hearing called a Sandoval hearing to determine in advance what if anything the prosecution can use to cross-examine the defendant about his criminal past. The purpose of the hearing is to weigh and balance the People’s interest in testing the defendant’s credibility and the defendant’s interest in ensuring that he is not convicted because a jury heard about prejudicial prior criminal conduct.
Earlier this month, a state appellate court issued a written opinion in a New York burglary case in which the court was tasked with determining if the defendant was entitled to a new trial when the prosecution brought up the fact that he had previously been convicted of a robbery that was currently in the process of being appealed. Ultimately, the court concluded that the lower court improperly allowed the defendant to be cross-examined regarding the prior robbery, and this error was not harmless. Thus, the court ordered a new trial to be conducted. As we have reported in the past this is not the first case to be revered for such errors. Please see our prior blog.
The Facts of the Case
During a trial for burglary, the defendant chose to testify on his own behalf, which is his constitutional right. After the defendant had finished answering the questions posed to him by his own attorney, the prosecution conducted cross-examination.
It was during this cross-examination that the prosecutor asked the defendant about a prior robbery conviction. Normally, evidence of prior criminal acts is not relevant at trial and may not be explored by the prosecution. However, under certain circumstances, convictions for crimes involving dishonesty – such as theft, robbery, etc. – may be the subject of cross-examination. In addition, one who shows through their past criminal conduct that they are willing to put their interests over those of society’s may be more willing to do so again by lying under oath.
