Nader v. General Motors Corp. (25 N.Y. 2d 560, 1970) was a court case in which author and automobile safety lecturer Ralph Nader claimed that General Motors had “conduct[ed] a campaign of intimidation against him in order to ‘suppress plaintiff's criticism of and prevent his disclosure of information’ about its products” regarding his book Unsafe at Any Speed. Mere information gathering is not sufficient for action under intrusion upon seclusion tort: "privacy is invaded only if the information sought is of a confidential nature and the defendant's conduct was unreasonably intrusive." Judge Brietel concluded that GM's actions "constitute intrusion upon privacy".
