The binding legal principles established are: (1) The Constitution is the source of courts' power to order personal costs against public officials who act in bad faith or with gross negligence in conducting litigation or discharging constitutional obligations. (2) Personal costs orders against public officials vindicate the Constitution and are necessary to hold public officials accountable when they breach their constitutional duties. (3) Public officials owe heightened duties in litigation, including obligations to be candid, transparent, and provide full and frank disclosure to courts. (4) Public litigants must produce complete rule 53 records including all documents relevant to proceedings under review. (5) The test for personal costs against public officials is bad faith or gross negligence, assessed objectively with reference to institutional competence and constitutional obligations. (6) Personal costs on an attorney and client scale constitute a form of double punishment requiring separate justification beyond grounds for ordinary personal costs. (7) Punitive costs on an attorney and client scale are justified only for extraordinary conduct warranting the court's rebuke, such as fraudulent, dishonest, vexatious conduct or abuse of court process. (8) The immunity under section 5(3) of the Public Protector Act applies only to conduct performed in good faith. (9) Appellate courts will not interfere with costs orders absent material misdirection, such as failure to exercise discretion judicially, influence by wrong principles, misdirection on facts, or reaching an unreasonable decision. (10) Personal costs orders do not undermine the independence of Chapter 9 institutions when properly applied to hold officials accountable for bad faith or grossly negligent conduct.
