A little less than two years after Alex Kozinski abruptly retired from the bench amid allegations of harassment and sexual misconduct, the former chief judge of the U.S. Court of Appeals for the Ninth Circuit is set to return to the court as an advocate.

Kozinski is scheduled to handle oral argument Monday on behalf of the son of Pulitzer Prize-winning author Paul Zindel, who is seeking to revive a copyright lawsuit against the filmmakers behind the Academy Award-winning film “The Shape of Water.” Kozinski’s client, whom he represents alongside co-counsel at Toberoff & Associates, claims the filmmakers and MacMillan Publishers, which produced a novelization of the movie, lifted multiple copyright-protected elements of Zindel’s play “Let Me Hear You Whisper.”
