Although Strauss-Kahn's attorneys had sued to stop Marcela Iacub's book, "Beautiful and beastly," from going on sale, they also praised the court's ruling, calling it "an excellent decision," Radio France Internationale reported Wednesday.
The court ordered the magazine Nouvel Observateur, which published excerpts from the book, to pay Strauss-Kahn $32,700 and print a statement of correction on its front page.
The author and the book's publisher were ordered to pay Strauss-Kahn $982,750.
Iacub had a seven-month affair with Strauss-Kahn in 2012. Her book is a fictionalized report of their relationship, RFI said.
Strauss-Kahn was director of the IMF when he was accused of sexual assault by a hotel maid in New York City in May 2011.
Until that point, he was a highly respected economist and politician who was frequently named as a possible candidate to run for a term as the president of France.
Since Strauss-Kahn stepped down from his role at IMF shortly after the incident in New York City became known to focus on his legal problems, other allegations of sexual promiscuity have surfaced.
