In Ignarski v. Norbut, 271 Ill. App. 3d 522, 529-30, 648 N.E.2d 285, 207 Ill. Dec. 829 (1995), the Court considered whether the defendant-attorneys in a legal malpractice lawsuit were equitably estopped from denying the underlying complaint stated a meritorious action by virtue of defendant Alex Norbut's conduct in the underlying litigation. Norbut filed a complaint on the plaintiff's behalf in the underlying lawsuit. During his deposition for the legal malpractice action, Norbut admitted he filed the lawsuit on plaintiff's behalf because, as a result of his research, he felt plaintiff had a meritorious claim worth pursuing. Plaintiff contended the defendants should not be allowed to deny what Norbut had previously admitted. The court recognized plaintiff essentially sought to dispose of the proximate cause requirement. Ignarski, 271 Ill. App. 3d at 529.
