Whether a nonresident manufacturer commits a "tortious act within this State" under Illinois Civil Practice Act section 17(1)(b) when negligent manufacture occurs outside Illinois but the resulting injury occurs in Illinois.
Holding
Yes. For purposes of section 17(1)(b), the alleged tort was committed in Illinois because the injury—the final event necessary to create liability—occurred there.
Reasoning
The court began with the accepted conflicts principle that a wrong occurs where the last event necessary to make the actor liable takes place. Although Titan's allegedly negligent manufacturing occurred elsewhere, negligence does not become actionable without injury. Because Gray's injury occurred in Illinois, Illinois was the place of the alleged tort.
Titan argued that the statute's phrase "tortious act" referred only to its conduct in manufacturing the valve, excluding the later injury. The court rejected that narrow reading: an act is tortious only because it causes injury, so injury is inseparable from the statutory phrase.
The court also favored a practical construction. Treating each component of a tort as territorially separate would encourage distracting litigation over where every element occurred. The statute instead should be read in light of convenience, justice, and its purpose of extending Illinois jurisdiction as far as due process permits.
