There is an inherent tension between the goals of bankruptcy law and the state law doctrine of constructive trust. A central tenet of bankruptcy policy is that similarly situated creditors should be treated equally: because an insolvent business or individual will not be able to pay all creditors in full, a proper bankruptcy system must provide as equitable a distribution to each of them as possible. Constructive trust law, on the other hand, works to the advantage of a single creditor – which always means the detriment of the others when everyone is competing for limited funds.

In a recent decision by the influential Third Circuit Court of Appeals, In re KB Toys Inc., 2013 U.S. App. LEXIS 23083 at *17 (3d Cir. Nov. 15, 2013), the Court decided that “the cloud on the claim” stemming from a preferential payment made to the original claimant continues with the claim, which then could be disallowed.
