(2) The Board can clearly establish at the time of the referral that the automatic stay under section 362 of the Bankruptcy Code has been lifted or is no longer in effect with respect to the debtor (or, if an individual, his or her spouse) and the debt was not discharged in the bankruptcy proceeding;
