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 highly-anticipated decision on a long-running bondholder dispute, the US Court of Appeals for the Second Circuit issued its judgment last week in Marblegate Asset Management LLC v Education Management Corp.
