United Retail and Wholesale Employees Teamsters Union Local No. 115 Pension Plan, et al. v. Yahn & Mcdonnell, Inc., et al.

Opinion summary

Etalia.ai summary of the majority opinion

The case involved the United Retail and Wholesale Employees Teamsters Union Local No. 115 Pension Plan, which sought to enforce withdrawal liability against Yahn & McDonnell, Inc., under the Multiemployer Pension Plan Amendments Act of 1980 (MPPAA). The MPPAA was designed to protect pension plans by requiring employers withdrawing from multiemployer plans to pay their share of unfunded vested benefits. Yahn & McDonnell argued that they were not liable for such payments because they had ceased operations before the enactment of MPPAA. The Supreme Court ruled in favor of Yahn & McDonnell, holding that applying withdrawal liability retroactively would violate due process rights as it imposed new obligations based on past actions without fair notice or opportunity for compliance.
