Depp sued Heard in 2019 for $50 million over an op-ed she wrote for the Washington Post alleging she was the victim of domestic abuse. She never identified Depp directly in the piece, but wrote that she is "a public figure representing domestic abuse."

Depp’s lawyers say the article falsely implies she was physically and sexually abused by Depp when the actors were married.
