N.Y. Correct. Law § 805
Persons committed to the custody of the department under an indeterminate sentence of imprisonment shall be assigned a work and treatment program as soon as practicable. No earlier than two months prior to the expiration of an incarcerated individual's minimum period of imprisonment, the commissioner shall review the incarcerated individual's institutional record to determine whether he or she has complied with the assigned program. If the commissioner determines that the incarcerated individual has successfully participated in the program he or she may issue the incarcerated individual a certificate of earned eligibility. Notwithstanding any other provision of law, an incarcerated individual who is serving a sentence with a minimum term of not more than six years and who has been issued a certificate of earned eligibility, shall be granted parole release at the expiration of his or her minimum term or as authorized by subdivision four of section eight hundred sixty-seven unless the board of parole determines that there is a reasonable probability that, if such incarcerated individual is released, he or she will not live and remain at liberty without violating the law and that his or her release is not compatible with the welfare of society. Any action by the commissioner pursuant to this section shall be deemed a judicial function and shall not be reviewable if done in accordance with law.
