N.Y. General Business Law § 345: Witnesses' immunity

§ 345. Witnesses' immunity. Upon any investigation before the attorney

general or his deputy or other officer designated by him, or in any

criminal proceeding before any court or grand jury, pursuant to or for a

violation of any of the provisions of this article, the attorney

general, his deputy or other officer designated by him, or the court or

grand jury, may confer immunity in accordance with the provisions of

section section 50.20 or 190.40 of the criminal procedure law. Provided,

that upon twenty-four hours written notice to the attorney general, in

any such criminal proceeding at which the attorney general or his deputy

is not present, immunity may be conferred; but where such notice has not

been given a witness who has had immunity otherwise properly conferred

upon him shall not be deprived thereof.
