(a) If the board determines that any overpayment has been made intentionally or made not incident to a bona fide and orderly discharge of a liability reasonably assumed by the insurer, surplus line broker, or Medi-Cal managed care plan to be imposed by law, no interest shall be allowed on the overpayment.
(b) If any insurer, surplus line broker, or Medi-Cal managed care plan which has filed a claim for refund requests the board to defer action on its claim, the board, as a condition to deferring action, may require the claimant to waive interest for the period during which the insurer, surplus line broker, or Medi-Cal managed care plan requests the board to defer action on the claim.
(c) This section shall become inoperative on July 1, 2012, and, as of January 1, 2013, is repealed, unless a later enacted statute, that becomes operative on or before July 1, 2012, deletes or extends the dates on which it becomes inoperative and is repealed.
