Fifteenth Court of Appeals Denies Mandamus Challenging Business Court Order in Foundation Dispute

The Fifteenth Court of Appeals denied a mandamus petition filed by three Highland foundations seeking to overturn a September 18, 2025 order issued by Judge William Whitehill of Business Court Division 1B in Dallas County. The per curiam opinion, issued by a panel consisting of Chief Justice Brister and Justices Field and Farris, held that relators failed to establish entitlement to mandamus relief in their dispute with Mark Patrick and several charitable foundation entities.
