Great caution must be taken when multi-count lawsuits are filed and a voluntary dismissal considered. Suppose one of the three counts of the complaint turns out to be unsustainable and a voluntary dismissal is taken as to Count II leaving Counts I and III. The voluntary dismissal as to that count II amounts to a dismissal with prejudice.
Suppose further that as the case remains, the case reaches a point where the plaintiff makes a decision to voluntarily dismiss without the remaining two-count complaint under Illinois Code of Civil Procedure §2-1009, which allows the refiling of the case within one year.
This is where it becomes very tricky. Under the Hudson v. City of Chicago, the Illinois Supreme Court set out the issue as: “Whether the involuntary dismissal of plaintiffs’ negligence claim and plaintiffs’ subsequent voluntary dismissal of their remaining willful and wanton misconduct claim (against the City of Chicago) barred the refiling of their willful and wanton misconduct claim under the doctrine of res judicata.” What the Illinois Supreme Court was looking at is that in Hudson, the original complaint was two counts. The first count sounded in negligence and the second willful and wanton misconduct. Under the law, the City and its employees had immunity under the Emergency Medical Services Systems Act. 210 ILCS 50/3.150.
