On March 19, 2021, the United States Court of Appeals for the Third Circuit issued a unanimous decision[1] affirming that the mutuality requirement of section 553(a) of the Bankruptcy Code must be strictly construed and, therefore, that triangular setoffs are not permissible in bankruptcy.

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.
