Through his work on behalf of Jackson's Estate Branca has become outspoken advocate of protecting the deceased from defamation. At a June, 2019, UCLA Law School panel titled “Truth Be Told? Documentary Films Today,” Branca stated: “The purpose of the First Amendment is supposedly getting at the truth, but the lack of defamation protection for an individual no longer living isn’t helpful in that regard. If copyright protection is life plus 75 years, there’s no reason a defamation suit shouldn’t be life plus 20, 30 or even 40 years.”
