Ill. Admin. Code tit. 95, § 400.1225
a) General. The imposing commander, his or her successor in command, or any superior commander may suspend, mitigate or remit punishment as a means of correcting behavior and rehabilitating the offender. If used correctly, these can be valuable tools in maintaining morale and discipline. This action can be taken on the commander's own initiative, or the SMF member can request the action. These commanders also have the authority to vacate suspended punishments or set aside punishments when appropriate.
1) Successor in Command. For these purposes, the successor in command may be either:
b) Suspension. To suspend punishment is to postpone application of all or part of it for a specified probationary period, with the understanding that it will be automatically remitted at the end of that period if the offender does not engage in further misconduct. Suspension is often warranted for a first offender or when there are persuasive matters in extenuation or mitigation.
c) Vacation of Suspension. A commander may vacate any suspended punishment, provided the punishment is of a type and amount he or she could impose, if the commander determines that the member has committed an offense during the period of suspension or has failed to meet a condition upon which the suspension was based. Vacation proceedings shall be recorded on NGIL Form 62-R. The action must be initiated before the end of the suspension period.
d) Mitigation. To mitigate punishment is to change it to a less severe punishment in quantity or type; however, the general nature of the punishment must remain the same. For example, restraints on liberty (i.e., restriction or extra duties) may not be mitigated to monetary punishments (i.e., forfeitures of pay), and a forfeiture of pay may be mitigated only to a lesser forfeiture of pay. Mitigation may be appropriate when the offender's subsequent good conduct merits a reduction in severity of the punishment, or when the punishment imposed was disproportionate to the offense or the offender.
f) Set Aside. When a commander determines that a member who was punished, or is being punished, has suffered a "clear injustice", the commander may cancel the punishment and restore the member's rights, privileges or property accordingly.
