Section 50.20 - Compulsion of evidence by offer of immunity1. Any witness in a legal proceeding, other than a grand jury proceeding, may refuse to give evidence requested of him on the ground that it may tend to incriminate him and he may not, except as provided in subdivision two, be compelled to give such evidence.2. Such a witness may be compelled to give evidence in such a proceeding notwithstanding an assertion of his privilege against self-incrimination if: (a) The proceeding is one in which, by express provision of statute, a person conducting or connected therewith is declared a competent authority to confer immunity upon witnesses therein; and(b) Such competent authority (i) orders such witness to give the requested evidence notwithstanding his assertion of his privilege against self-incrimination, and (ii) advises him that upon so doing he will receive immunity.3. A witness who is ordered to give evidence pursuant to subdivision two and who complies with such order receives immunity. Such witness is not deprived of such immunity because such competent authority did not comply with statutory provisions requiring notice to a specified public servant of intention to confer immunity.4. A witness who, without asserting his privilege against self-incrimination, gives evidence in a legal proceeding other than a grand jury proceeding does not receive immunity.5. The rules governing the circumstances in which witnesses may be compelled to give evidence and in which they receive immunity therefor in a grand jury proceeding are prescribed in section 190.40.N.Y. Crim. Proc. Law § 50.20
