People v. Diaz, 29 N.Y.3d 1126 (2017)

A defendant’s statutory right to testify before a grand jury is violated when the prosecution demands an unaltered waiver of immunity that includes provisions beyond the statutory requirements of CPL 190.45.

Summary

The New York Court of Appeals held that the defendant’s right to testify before a grand jury was violated when the prosecution refused to allow him to testify after he signed a waiver of immunity with certain provisions struck out. The court found that the defendant had satisfied the statutory requirements for a waiver of immunity under CPL 190.45, which only requires a waiver of the privilege against self-incrimination. The prosecution’s insistence on an unaltered waiver, including additional provisions, was deemed an infringement upon the defendant’s right to testify. The court emphasized that the defendant only needed to meet the requirements of the statute, and nothing more, to make a valid written waiver of immunity.

Facts

The defendant, Diaz, was indicted on charges of attempted criminal possession of a weapon and other related offenses. Diaz served notice of his intent to testify before the grand jury. The prosecution provided him with a waiver of immunity form which, in addition to the statutorily required provisions, also contained three additional paragraphs relating to his right to counsel, the scope of questioning, and the use of his testimony. Diaz struck out those three additional provisions and signed the form. The Assistant District Attorney (ADA) informed Diaz that he would not be allowed to testify unless he signed the unaltered waiver. Diaz did not sign the unaltered form and was consequently not permitted to testify.

Procedural History

After a jury conviction, the trial court found the defendant guilty and dismissed the indictment. The Appellate Division vacated the conviction, finding the defendant was denied his right to testify before the grand jury. The People appealed this decision to the New York Court of Appeals.

Issue(s)

Whether a defendant’s statutory right to testify before a grand jury is violated when the prosecution requires an unaltered waiver of immunity containing provisions beyond those mandated by CPL 190.45?

Holding

Yes, because the defendant complied with the statutory requirements for a waiver of immunity, the prosecution’s insistence on additional, non-statutory terms violated his right to testify.

Court’s Reasoning

The Court of Appeals affirmed the Appellate Division’s decision. The court found that Diaz met the necessary requirements for a valid written waiver of immunity under CPL 190.45 when he signed the document, even after striking out the additional provisions. The court reasoned that CPL 190.45 is clear, straightforward, and concise in its requirements. The court referenced that a waiver of immunity requires only a written instrument waiving the privilege against self-incrimination. The additional provisions regarding the right to counsel, the scope of questioning, and the use of testimony were not required by the statute. The prosecution improperly demanded an unaltered waiver. The Court of Appeals reiterated that the defendant’s right to testify before the grand jury “must be scrupulously protected.”

The court emphasized that the prosecutor was not authorized to impose any additional requirements. A valid waiver of immunity was established when Diaz agreed to waive his right to self-incrimination. The court stated, “When a defendant meets the waiver of immunity requirements of CPL 190.45, he or she must be permitted to testify.” The court noted that a waiver of immunity, per the statute, requires only a written instrument waiving the privilege against self-incrimination.
