(December 27, 2017, 9:50 AM EST) -- CINCINNATI — A construction company that terminated its collective bargaining agreement (CBA) with an ironworkers union, ending its contributions to a multiemployer pension plan, did not owe withdrawal liability under the Mutiemployer Pension Plan Amendments Act (MPPAA) when it later used other workers for some tasks it previously had ironworkers perform as the work was assigned through an agreement incorporated into the CBA, a Sixth Circuit U.S. Court of Appeals panel ruled Dec. 13 (Stevens Engineers & Constructors, Inc. v. Local 17 Iron Workers Pension Fund, et al., No. 16-4098/4099, 6th Cir., 2017 U.S. App. LEXIS 25134)....
