The finality of asset sales and other transactions in bankruptcy is an indispensable feature of U.S. bankruptcy law designed to maximize the value of a bankruptcy estate as expeditiously as possible for the benefit of all stakeholders. To promote such finality, section 363(m) of the Bankruptcy Code prohibits reversal or modification on appeal of an order authorizing a sale or lease to a "good-faith" purchaser or lessee unless the party challenging the sale obtains a stay pending appeal. What constitutes "good faith" has sometimes been disputed by the courts.

Since May 2023, the U.S. Supreme Court has issued three decisions addressing or potentially impacting issues of bankruptcy law. These included rulings concerning the abrogation of sovereign immunity for Native American tribes under the Bankruptcy Code, and for instrumentalities of Puerto Rico under a similar statute enacted in 2016 allowing the Commonwealth to restructure its debts. The Court also handed down an opinion concerning a homeowner's entitlement to the surplus proceeds of a real estate tax foreclosure sale.

Whether a dispute that is subject to arbitration can or must be referred to arbitration after one of the parties to a prepetition arbitration agreement files for bankruptcy has long been a source of disagreement among bankruptcy and appellate courts due to a perceived conflict between the Federal Arbitration Act and the Bankruptcy Code. The U.S. Bankruptcy Court for the Northern District of Illinois recently provided some useful guidance regarding this issue.

To prevent "trafficking in corporate shells," the Bankruptcy Code prohibits any discharge of corporate or partnership debts if the debtor is not an "individual" and, in a chapter 11 case, if the debtor proposes a liquidating chapter 11 plan contemplating the cessation of the debtor's business following confirmation.

A bankruptcy trustee's ability to avoid and recover pre-bankruptcy preferential transfers is essential to preserving or augmenting the estate for the benefit of all stakeholders. In 2019, however, the Bankruptcy Code was amended to add a due diligence requirement to the Bankruptcy Code's preference avoidance provision, apparently as a way to minimize the volume of speculative and coercive preference litigation.

In Czyzewski v. Jevic Holding Corp., 137 S. Ct. 973 (2017), the U.S. Supreme Court held that the Bankruptcy Code does not allow bankruptcy courts to approve distributions to creditors in a "structured dismissal" of a chapter 11 case that violate the Bankruptcy Code's ordinary priority rules without the consent of creditors. However, because the Court declined to express any "view about the legality of structured dismissals in general," many open questions remain regarding the structured dismissal mechanism.

Exculpation clauses limiting the liability of certain entities for actions taken in connection with a bankruptcy case are a common feature of chapter 11 plans. However, courts disagree over the permitted scope of such clauses. They also disagree as to whether an order confirming a chapter 11 plan that includes exculpation and third-party release provisions is insulated from appellate review under the doctrine of "equitable mootness."

To prevent landlords under long-term real property leases from reaping a windfall for future rent claims at the expense of other creditors, the Bankruptcy Code caps the amount of a landlord's claim against a debtor-tenant for damages "resulting from the termination" of a real property lease.

To shield bankruptcy trustees and certain other entities from litigation arising from actions taken in their official capacity, the "Barton doctrine"—now more than a century old—provides that such litigation may be commenced only with the authority of the appointing court. The doctrine has certain exceptions, one of which—the "ultra vires exception"—was recently examined by the U.S. Court of Appeals for the Fifth Circuit as an apparent matter of first impression.

If any class of creditors under a chapter 11 plan is "impaired," the Bankruptcy Code provides that the plan can be confirmed by the bankruptcy court only if at least one impaired class of non-insider creditors votes to accept the plan. This "impaired class acceptance" requirement—stated in section 1129(a)(10) of the Bankruptcy Code—is straightforward in cases involving a single debtor, or in cases where the bankruptcy estates of several debtors are "substantively consolidated" so that the assets and liabilities of each debtor are deemed to belong to a single consolidated entity.
