A lawsuit filed by former Walt Disney Co. director Roy Disney that seeks to void the company’s last board election will go to trial Aug. 10.

Delaware Chief Chancery Court Judge William Chandler III set the trial date Tuesday and will preside without a jury. Roy Disney and former director Stanley Gold claim investors were misled about the search for a successor to outgoing Chief Executive Michael Eisner. They said the board promised an open search when it already decided to promote company President Robert Iger to the position.

The May 9 suit was filed after Burbank-based Disney refused to provide the former board members with information about the selection process.

The lawsuit accused Walt Disney Co., Iger, Michael Eisner and directors Judith Estrin, John Chen, Alwyn Lewis, Monica Lozano, George Mitchell and Leo Donovan with fraud and breach of duty of disclosure in connection with the board’s public statements about the search for a replacement for Eisner.
