In one sentenceRule 558 gives the trial court ongoing power to fix clerical and calculation mistakes in a traffic, conservation, or ordinance sentence, even after the case is on appeal.
(a)In traffic cases, conservation cases, or ordinance violation cases, the circuit court retains
jurisdiction to correct the following sentencing errors at any time following judgment after notice to the parties, including during the pendency of an appeal, on the court’s own motion, or on motion of any party:
(1)Errors in the imposition or calculation of fines, fees, assessments, or costs;
(2)Errors in the application of per diem credit against fines;
(3)Errors in the calculation of presentence custody credit; and
(4)Clerical errors in the written sentencing order or other part of the record resulting in a discrepancy between the record and the actual judgment of the court.
(b)Where a circuit court’s judgment pursuant to this rule is entered more than 30 days after the final judgment, the judgment constitutes a final judgment on a justiciable matter and is subject to appeal in accordance with Supreme Court Rule 303.
(c)No appeal may be taken by a party from a judgment of conviction on the ground of any sentencing error specified above unless such alleged error has first been raised in the circuit court. When a post-judgment motion has been filed by a party pursuant to this rule, any claim of error not raised in that motion shall be deemed forfeited.
(d)If a motion is filed or judgment pursuant to this Rule is entered after a prior notice of appeal has been filed, and said appeal remains pending, the pending appeal shall not be stayed. Any appeal from a judgment entered pursuant to this rule shall be consolidated with the pending appeal.
(e)In all traffic, conservation, or ordinance violation cases pending on appeal as of March 1, 2019, or appeals filed thereafter in which a party has attempted to raise sentencing errors covered by this rule for the first time on appeal, the reviewing court shall remand to the circuit court to allow the party to file a motion pursuant to this rule.
(f)No motion filed pursuant to this rule shall be subject to a filing fee.
Plain-English Summary
Sentencing paperwork can contain errors — a miscalculated fine, the wrong credit for time already served, a clerical slip that doesn't match what the judge ordered. Rule 558 lets the circuit court fix those specific problems at any time after judgment, on its own motion or a party's, as long as everyone gets notice.
If the correction happens more than 30 days after the original final judgment, that correction becomes its own appealable final judgment under Rule 303. But a party can't raise one of these sentencing errors for the first time on appeal — it has to go to the circuit court first, or it's forfeited. Filing this kind of motion doesn't cost anything, and if an appeal is already pending, the correction doesn't stop it; any new appeal from the correction gets folded into the pending one.
