Rule 706 Appointed Experts Immune From Suit. On May 7, 2009, Briggs and Morgan obtained a significant victory that will have a broad effect upon the role of experts in litigation. The Minnesota Supreme Court concluded that experts appointed pursuant to Rule 706 of the Minnesota Rules of Evidence are immune from suit for acts performed pursuant to their appointment. Public policy supported affording immunity to ensure that such experts would be able to provide vital services to the judiciary without being influenced by fear of personal liability or harassing litigation.
