Cent. States SE & SW Areas Pension Fund v. Waste Mgmt of MI, Inc.

by
The employer sought an early withdrawal from its obligation to make pension contributions to a multiemployer pension fund; it entered into a new collective bargaining agreement, six weeks before expiration of the existing agreement, that abrogated its obligation to make payments to the fund. The fund sued under the Employee Retirement Income Security Act of 1974, 29 U.S.C. 1145. The district court entered summary judgment in favor of the fund. The Seventh Circuit affirmed, rejecting an argument that the agreement was ambiguous in providing that the employer could not “prospectively” change its obligation.
