The binding legal principles established are: (1) An appellant cannot accept a lower court's judgment on the merits but challenge the costs order by seeking to relitigate those merits - this is impermissible. (2) A lower court exercises a true discretion in awarding costs orders. An appellate court will only interfere where there was a material misdirection - it is insufficient to merely show the order was wrong. Interference is warranted only where: the discretion was not exercised judicially; the decision was influenced by wrong principles; there was a misdirection on facts; or the decision could not reasonably have been reached by a court properly directing itself. (3) Public officials, including the President, must observe heightened standards in litigation as the Constitution's principal agents. They must not mislead or obfuscate, must do right and do it properly, must be candid, and must place a full and fair account of facts before a court. (4) A higher duty is imposed on public litigants to respect the law, fulfill procedural requirements, and tread respectfully when dealing with rights. (5) The Constitution endows courts with power to impose personal liability for costs on public officials who act contrary to their constitutional obligations - this is an important constitutional tool. (6) Public officials, not taxpayers, should pay costs of litigation when their defiance of constitutional obligations is egregious. (7) A punitive costs order is justified where conduct is 'extraordinary' and worthy of rebuke, including where it would be unfair to expect a party to bear costs occasioned by vexatious litigation or conduct that amounts to abuse of process. (8) The President must exercise powers and responsibilities for public benefit, not personal advancement, and must fulfill all constitutional obligations however unpleasant.
