Ill. S. Ct. R. 273 (2026)

Digitally signed by Reporter of Decisions Reason: I attest to the accuracy and integrity of this document

Rule 273. Effect of Involuntary Dismissal Unless the order of dismissal or a statute of this State otherwise specifies, an involuntary dismissal of an action, other than a dismissal for lack of jurisdiction, for improper venue, or for failure to join an indispensable party, operates as an adjudication upon the merits.

Committee Comments This rule is based upon Rule 41(b) of the Federal Rules of Civil Procedure and sets to rest the question of the effect of an involuntary dismissal other than those excepted by the rule. Cf. Lurie v. Rupe, 51 Ill. App. 2d 164, 176, 201 N.E.2d 158 (1st Dist. 1964).
