Formula for an indeterminate returned parole violator with a consecutive determinate new term and indeterminate new term. The new terms are consecutive to each other, and consecutive to the prior indeterminate time owed. To compute the parole eligibility date, add 6/7 of the determinate term and the new indeterminate minimum term; then subtract the jail time, add the prior indeterminate minimum time owed, and add the date received.Compute the Maximum Expiration dates twice; compare them, and whichever is longer controls. To compute the first ME, add the determinate term and the new indeterminate minimum term; then subtract the jail time, add the prior indeterminate minimum time owed, and add the date received. To compute the second ME, subtract the jail time from the new indeterminate maximum term; then add the prior indeterminate maximum time owed, and add the date received. Compute the good time and subtract it from the controlling Maximum Expiration date. To compute the good time, add 1/7 of the determinate term, 1/3 of the indeterminate maximum term and 1/3 of the prior indeterminate maximum time owed. *Penal Law 70.40 (1)(b)(ii) prohibits inmates from being eligible for CR before they are eligible for parole.
