Ralph Nader, who has been a critic of General Motors Corp. for several years, claims that when General Motors learned that Nader was about to publish a book entitled Unsafe at Any Speed, criticizing one of its automobiles, it decided to conduct a campaign of intimidation against him. Specifically, Nader claims that GMC (a) Conducted a series of interviews with Nader’s acquaintances, questioning them about his political, social, racial, and religious views; (b) Kept him under surveillance in public places for an unreasonable length of time, including close observation of him in a bank; (c) Caused him to be accosted by women for the purpose of entrapping him into illicit relationships; (d) Made threatening, harassing, and obnoxious telephone calls to him; (e) Tapped his telephone and eavesdropped by means of mechanical and electronic equipment on his private conversations with others; and (f) Conducted a ‘‘continuing’’ and harassing investigation of him. Nader brought suit against GMC for invasion of privacy. Which, if any, of the alleged actions would constitute invasion of privacy?
