Further evidence that libel lawsuits, though not easy to win, can indeed sometimes yield substantial recovery; for the details on the deal, which I assume is being paid for by Mensa's liability insurance company, see here. Here's a summary of the undisputed facts, to give a sense of the underlying claim (in Levine v. American Mensa Ltd.):
(1) Mr. Levine was a member of American Mensa for thirty years up until 2008, when he was expelled from the organization. Mr. Levine objected to his expulsion from membership as unfair and unjustified.
(2) Since his expulsion in 2008, Mr. Levine has attended many of the yearly Mensa Annual Gatherings which occur in different cities across the United States.
(3) The events of this lawsuit relate primarily, but not exclusively, to the Mensa Annual Gathering that occurred at the JW Marriott Hotel in Indianapolis, Indiana in July 2018.
(4) During the week of July 4, 2018, Mr. Levine contends that authorized representatives of Mensa, including its Chairwoman LaRae Bakerink published statements, both written and oral, accusing Mr. Levine of "verbally abusing" multiple members, and of "stalking" and "harassing" a Mensa leader, staff and members during the 2018 AG.
