Full Text of Ill. S. Ct. R. 187
Plain-English Summary
Forum non conveniens lets a court send a case elsewhere, or dismiss it, when another location would serve the litigation better. Rule 187 requires that motion to be filed within 90 days after the deadline for that party’s answer, a rule designed to prevent the tactic from being used as a late-stage surprise.
Hearings on these motions have to allow the parties enough time to gather evidence on the factual questions the motion raises, and the parties can support or oppose the motion with affidavits and other competent evidence. Whatever the court decides on those facts is only about where the case belongs, not about the merits of the underlying claims.
When a court grants an intrastate transfer, the clerk of the losing court certifies and sends the case file to the new court, which then treats the case as if it originated there, with transfer costs falling on whoever asked for the move. A dismissal on forum non conveniens grounds comes with built-in conditions: the defendant must accept service in the new forum if the plaintiff refiles within six months, and must waive a statute-of-limitations defense if that period has by then run in the new forum. If the defendant balks at those conditions, or if the other forum refuses to take the case, the original court can reinstate the action.
