She had filed suit against the playwright of Dusky Sally in 1987, shortly before a production was to open at the Walnut Street Theatre in Philadelphia. She said his work infringed on her copyright for her novel Sally Hemings because it borrowed her fictional ideas. Judge Robert F. Kelly concluded that while laws were not enacted to inhibit creativity ... it is one thing to inhibit creativity and another to use the idea-versus-expression distinction as something akin to an absolute defense – to maintain that the protection of copyright law is negated by any small amount of tinkering with another writer's idea that results in a different expression." He also said, the similarity between the two works is so obvious and so unapologetic that an ordinary observer can only conclude that Burgess felt he was justified in copying 'Sally Hemings,' or at least that there was no legal impediment to doing so, assuming a few modifications were made." The resulting decision constituted a significant victory for artists and writers, reinforcing protection for creative ideas even when expressed in a slightly different form." Chase-Riboud v. Dreamworks lawsuit In 1997, Chase-Riboud settled a suit against DreamWorks for $10 million on charges of copyright infringement of her novel about the Amistad mutiny, Echo of Lions. The author claimed that the screenplay for Steven Spielberg's film Amistad (1997) plagiarized her novel on the topic. It was finally established that David Franzoni, the sole credited screenwriter on Amistad, had spent three years, beginning in 1993, writing a script based on Chase-Riboud's book, Echo of Lions. This was under an option held by Dustin Hoffman's Punch Productions. Franzoni claimed he had never read Chase-Riboud's book, which she had sold to Dustin Hoffman's production company. Burt Fields, DreamWorks main lawyer, was at the same time, unbeknownst to Chase-Riboud's attorneys, a stockholder, lawyer and board member of Punch Productions. He did not recuse himself from the suit, but had Punch Productions dropped from the original complaint. Franzoni was never obliged to testify under oath. He may have carried over some of his thinking to his screenplay for Amistad. When Chase-Riboud filed a second suit against DreamWorks in France, the dispute was quickly settled out of court for an undisclosed amount days before the 1998 Oscar nominations were announced. Poetry Chase-Riboud's first work of poetry, From Memphis & Peking (1974), was edited by Toni Morrison and published to critical
