N.Y. Comp. Codes R. & Regs. tit. 9, § 519.5
(1) General. The imposing commander, his or her successor-in-command, or the next superior authority may, in accordance with the time prescribed in the MCM:
(2) Meaning of successor-in-command. As used in paragraph 134, MCM, a successor-in-command is the officer who has authority to impose the same kind and amount of punishment of a member concerned that was initially imposed or was the result of a modification and who:
(3) Recording of action. Any action of suspension, mitigation, remission or setting aside, taken by an authority will be recorded according to notes 9 and 10, DMNA form 1057 (Appendix L-2[A16]) or DMNA form 1059 (Record of Supplementary Action Under Article 15) exhibit 3.
(b) Suspension.
Ordinarily, punishment is suspended to grant a probational period during which a member may show that he or she deserves a remission of the remaining suspended punishment. An executed punishment of reduction or fine may be suspended only within a period of four months after the date imposed. Suspension of punishment may not be for a period longer than six months from the suspension date. Further misconduct by the member, within the period of suspension, may be grounds for vacation of the suspended portion of the punishment.
(c) Vacation.
(1) A commander may vacate any suspended punishment, provided the punishment is of the type and amount he or she could impose. There is no appeal from a decision to vacate a suspension. The following will be recorded according to notes 8 and 9 on DMNA form 1057 (Appendix L-2[A16]):
(4) In cases involving punishments other than reduction and fine, the member will be informed of the basis of the proposed vacation and should be given an opportunity to respond, either orally or in writing. Failure to provide notification and an opportunity to appear or rebut the information may result in the record of punishment being inadmissible in a subsequent court-martial, but will not, by itself, render a vacation action void.
(d) Mitigation.
(1) General.
(2) Appropriateness. Mitigation is appropriate when:
(3) Limitation on mitigation.
(ii) Although a suspended punishment may be mitigated to a punishment of a lesser quantity or quality (which is also suspended for a period not greater than the remainder of the period for which the punishment mitigated was suspended), it may not, unless the suspension is vacated, be mitigated to an unsuspended punishment. (See paragraph [f][3] of this section for the time period within which reduction ordinarily may be mitigated, if appropriate, to a fine).
(e) Remission.
This is an action whereby any portion of the unexecuted punishment is cancelled. Remission is appropriate under the same circumstances as mitigation. An unsuspended reduction is executed upon imposition and thus cannot be remitted, but may be mitigated or set aside. The death, discharge, or separation from the service of a member punished remits any unexecuted punishment. A member punished under section 130.15 will not be held beyond his or her expiration of term of service (ETS) to complete any unexecuted punishment.
(f) Setting aside and restoration.
(a) Clemency.
