An arbitrator has decided in favor of Meta in a case the company brought against Sarah Wynn-Williams, the former Meta employee who wrote a memoir published this week detailing alleged claims of misconduct at the company. Macmillan Publishers and its imprint that published the memoir, Flatiron Books, were also named as respondents.

The memoir, titled Careless People: A Cautionary Tale of Power, Greed, and Lost Idealism, details alleged claims of sexual harassment, including by current policy chief Joel Kaplan, who was her boss, according to NBC News.

In the decision, the arbitrator said Wynn-Williams must stop making disparaging remarks against Meta and its employees and, to the extent that she can control, cease further promoting the book, further publishing the book, and further repetition of previous disparaging remarks. The decision also says she must retract disparaging remarks from where they have appeared.

However, it’s unclear if this arbitrator actually has the authority to halt the publishing of the book or if Wynn-Williams can stop the creation of future versions; as of this writing, it’s currently for sale at stores like Amazon and Barnes & Noble. In the decision, the arbitrator noted that the lawyer representing Macmillian and Flatiron objected to its jurisdiction. Wynn-Williams appears to have signed an arbitration agreement when she left Meta in 2017.

Meta, Macmillan, and Flatiron didn’t immediately reply to requests for comment.

“This ruling affirms that Sarah Wynn-Williams’ false and defamatory book should never have been published,” Meta spokesperson Andy Stone says in a statement. “This urgent legal action was made necessary by Williams, who more than eight years after being terminated by the company, deliberately concealed the existence of her book project and avoided the industry’s standard fact-checking process in order to rush it to shelves after waiting for eight years.”
