Case Summary

Disposition

Reversed in Part

The case concerns whether various affiliated trucking-dealership entities and their owners are liable under ERISA/MPPAA for delinquent pension contributions and withdrawal liability owed to the IAM National Pension Fund. The 12th Circuit affirmed the district court on some issues (allocation of a $1.8 million payment to interest and single-employer liability of the Sales entities), but reversed on others (interest-rate increase, pleading sufficiency for delinquent-contribution claim, and personal liability of the Bouchers) and remanded for further proceedings.

Legal Issue

Which legal standard applies to determine whether two nominally separate entities should be treated as a single employer for ERISA delinquent-contribution actions—the relaxed NLRB single-employer test or the traditional common-law veil-piercing standard?

Circuit Positions

Circuit 1DC Circuit(this circuit)

Apply the NLRB four-factor single-employer test (interrelated operations, common management, centralized control of labor relations, common ownership) to ERISA delinquent-contribution claims.

Circuit 8Circuit 9Circuit 11

Apply the traditional common-law veil-piercing/alter-ego standard and reject use of the NLRB single-employer test for ERISA delinquent-contribution claims.

Conflict Summary

The First and Twelfth Circuits apply (or, in the 12th Circuit’s case, ‘assume without deciding’ but nonetheless use) the NLRB’s four-factor single-employer test, which more readily disregards corporate separateness. The Eighth, Ninth, and Eleventh Circuits require courts to use the stricter common-law standard, under which corporate separateness is pierced only for fraud or comparable injustice.
