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 the world of private equity, vast sums of money are raised by private investors who pool their money into collective funds in order to acquire companies, i.e., a “portfolio company”, with the goal of eventually flipping the portfolio company at a significant profit. Sometimes, however, that bet goes wrong, and the portfolio company is sold at a loss or, worse, liquidated in bankruptcy.
