Harry Potter author J.K. Rowling has won her long-running battle with a fan who planned to publish an unauthorized guide to her wizard franchise.

Rowling began legal proceedings against writer Steve Vander Ark and publisher RDR Books last year after learning of their plans to release The Harry Potter Lexicon.

On Monday New York district court Judge Robert Patterson ruled in Rowling's favor and banned the encyclopedia-style project's release.

Patterson told the court that RDR "failed to establish an affirmative defense of fair use."
