Ill. Sup. Ct. R. 329
The record on appeal shall be taken as true and correct unless shown to be otherwise and corrected in a manner permitted by this rule. Material omissions or inaccuracies or improper authentication may be corrected by stipulation of the parties or by the trial court, either before or after the record is transmitted to the reviewing court, or by the reviewing court or a judge thereof. Any controversy as to whether the record accurately discloses what occurred in the trial court shall be submitted to and settled by that court and the record made to conform to the truth. If the record is insufficient to present fully and fairly the questions involved, the requisite portions may be supplied at the cost of the appellant. If necessary, a supplement to the record may be certified and transmitted. The clerk of the circuit court shall prepare a certified supplement to the record which shall be filed in the reviewing court upon order issued pursuant to motion.
Ill. Sup. Ct. R. 329
Committee Comments
(Revised May 1982)
This rule is a comprehensive provision covering amendment of the record on appeal, correction of improper authentication, and the settling of any questions concerning whether the record conforms to the truth. It contains portions of former Rules 36(3) and (4). Under this sweeping provision, it will be possible to supply omissions, correct inaccuracies or improper authentication, or settle any controversy as to whether the record on appeal accurately discloses what occurred at the trial by the procedure that will most appropriately solve the particular problem. In view of the liberal terms of this paragraph, the rather elaborate provisions of former Rule 36(4), requiring that a claim as to improper authentication be raised by motion before or at the time of the filing of the brief of the party making the claim, were eliminated as no longer necessary. Unless there is some real prejudice involved, there will be no incentive for claiming improper authentication.
Rule 329 was amended in 1982 to permit a single judge of the reviewing court to correct the record.
