An opinion issued earlier this year by the Delaware Bankruptcy Court in In re SemCrude, L.P., et al. (Bankr. Del., No. 08-11525; January 9, 2009) may end much of the practice of so-called “triangular setoffs” by creditors in bankruptcy cases. The Court in SemCrude found that creditors violate section 553 of the Bankruptcy Code by setting off amounts among multiple debtors, even when exercising contractual assignment rights. This ruling is likely to have far-reaching impact given the dearth of case law on this fairly common contractual provision.
