Respondent did not assume any role of especial prominence in the affairs of society, other than perhaps Palm Beach society, and she did not thrust herself to the forefront of any particular public controversy in order to influence the resolution of the issues involved in it….

Dissolution of a marriage through judicial proceedings is not the sort of “public controversy” referred to in Gertz, even though the marital difficulties of extremely wealthy individuals may be of interest to some portion of the reading public. Nor did respondent freely choose to publicize issues as to the propriety of her married life. She was compelled to go to court by the State in order to obtain legal release from the bonds of matrimony. We have said that in such an instance “[r]esort to the judicial process … is no more voluntary in a realistic sense than that of the defendant called upon to defend his interests in court.
