(1) After demand, the administrator may bring a civil action against a creditor to recover actual damages sustained and excess charges paid by one (1) or more debtors who have a right to recover explicitly granted by this act. In a civil action under this subsection, penalties may not be recovered by the administrator. The court shall order amounts recovered under this subsection to be paid to each debtor or set off against his obligation. A debtor’s action, except a class action, takes precedence over a prior or subsequent action by the administrator with respect to the claim of that debtor. A debtor’s class action takes precedence over a subsequent action by the administrator with respect to claims common to both actions, but the administrator may intervene. An administrator’s action on behalf of a class of debtors takes precedence over a debtor’s subsequent class action with respect to claims common to both actions. Whenever an action takes precedence over another action under this subsection, the latter action may be stayed to the extent appropriate while the precedent action is pending and dismissed if the precedent action is dismissed with prejudice or results in a final judgment granting or denying the claim asserted in the precedent action. A defense available to a creditor in a civil action brought by a debtor is available to him in a civil action brought under this subsection.
