The ability of a bankruptcy court to reorder the priority of claims or interests by means of equitable subordination or recharacterization of debt as equity is generally recognized. Even so, the Bankruptcy Code itself expressly authorizes only the former of these two remedies. Although common law uniformly acknowledges the power of a court to recast a claim asserted by a creditor as an equity interest in an appropriate case, the Bankruptcy Code is silent upon the availability of the remedy in a bankruptcy case.
