N.Y. Comp. Codes R. & Regs. tit. 7 § 290.1
Certain inmates serving either a determinate or indeterminate sentence for a crime that is not a merit eligible offense as defined in Correction Law section 803, may be eligible to earn a six-month Limited Credit Time Allowance (LCTA) against their sentences pursuant to Correction Law section 803-b, provided that they have achieved certain significant programmatic accomplishments, have not committed a serious disciplinary infraction or maintained an overall poor institutional record, and have not filed any frivolous lawsuits. In the case of an inmate serving a sentence with a maximum term of life for an eligible A-I felony, the six-month LCTA benefit is subtracted from the minimum period to establish the inmate's LCTA date. In the case of all other LCTA eligible offences, the LCTA benefit is subtracted from the conditional release date to establish the inmate's LCTA date. An LCTA benefit is a privilege to be earned by the inmate and no inmate has the right to demand or require that any such allowance be granted. This directive sets forth the policy and procedures for granting or withholding an LCTA benefit.
