Rulings on motions in limine remain subject to reconsideration by the court throughout the trial. Whether granted or denied, a motion in limine generally does not preserve issues for review. See, e.g., Illinois State Toll Highway Authority v. Heritage Standard Bank & Trust Co., 163 Ill. 2d 498, 502, 206 Ill. Dec. 644, 645 N.E.2d 896 (1994) (denial of motion in limine in a civil case does not preserve the issue for appeal if there is no contemporaneous objection at least the first time the evidence is offered at trial); Konieczny v. Kamin Builders, 304 Ill. App. 3d 131, 709 N.E.2d 695, 237 Ill. Dec. 440 (3d Dist. 1999) ("whether granted or denied, a motion in limine does not preserve issues for review").
The bottom line: If a motion in limine seeking exclusion of evidence is denied, the moving party should still object to the evidence at trial in order to preserve the issue for review.
