Recently, the U.S. Supreme Court issued a number of significant ERISA cases. In its 2013-14 term, the Supreme Court decided two ERISA-based appeals – Fifth Third Bancorp v. Dudenhoeffer and Heimeshoff v. Hartford Life & Acc. Ins. Co. In the current 2014-15 term, the Supreme Court already issued one ERISA decision in M&G Polymers USA, LLC v. Tackett, and will issue another ERISA decision soon in Tibble v. Edison Int’l. Although these four cases have received much attention within the ERISA community, each year there are hundreds of other decisions issued by federal appellate and district courts that also impact a plan sponsor’s daily administration of welfare and retirement plans. In fact, many of these district court and appellate decisions are interpreting issues raised or addressed in these Supreme Court opinions. This article will address a few of these cases, which may not have received a lot of attention by the press, but could have long-lasting impacts on plan administration and litigation in future years.
