Reported by Kent Morlan
Michael Gibson has twice unsuccessfully sued Greg, or Delores, or both for claims relating to GFLP. In the more recent of the two, Michael sued GFLP and Delores, alleging she had breached fiduciary duties as the general partner.
At the heart of the dispute was Michael's overarching theory that Delores lacks capacity to make decisions for GFLP. He claims that Greg is acting as GFLP's de facto general partner and has violated various fiduciary duties in concert with Ronayne. Michael also alleges that Greg and Joan tortiously interfered with his existing and prospective business relationship with GFLP.
Affirmed on appeal.
