(a) Failure to mail notice to a person under AS 42.40.180(a) or 42.40.190(a) does not invalidate an action taken by the board.
(b) An interested person may challenge a rule adopted by the board by bringing an action in the superior court. In addition to other grounds, a court may declare a change invalid (1) for substantial failure by the board to comply with AS 42.40.180 or 42.40.190; or
(2) if the rule was adopted under AS 42.40.190, upon the grounds that the emergency rule was not necessary for the orderly operation of the corporation's facilities or programs.
