There are four generally recognized invasion of privacy claims:
• Appropriation, for the defendant's benefit or advantage, of the plaintiff's name or likeness;
• Public disclosure of private facts;
• Publicity that places the plaintiff in a false light in the public eye; and
• Intrusion upon the plaintiff's physical and mental solitude or seclusion.
Illinois courts have recognized all four of these causes of action. Doubts about the validity of intrusion-on-seclusion claims were dispelled by the Illinois Supreme Court in Lawlor v. North American Corp. of Illinois, 983 N.E.2d 414 (Ill. 2012). An employer could be found liable on this basis, the court ruled, when it hired detectives who impersonated an employee to obtain her personal phone records.
