Building & Construction Trades Council of the Metropolitan District v. Associated Builders & Contractors of Massachusetts/Rhode Island, Inc.

Background

A Massachusetts state agency (the MWRA) ran a large, court-ordered cleanup of Boston Harbor and hired a manager to run the construction project. The manager negotiated a ten-year prehire project labor agreement with a building trades council that required contractors on the job to follow union hiring and union-security rules. A contractors’ group sued, arguing the agency’s bid rule conflicted with federal labor law, and lower courts split on whether the rule should be blocked.

Reasoning

The key question was whether federal labor law prevents a state, when acting as a buyer of services, from insisting that contractors accept a valid prehire union agreement. The Court distinguished two kinds of federal pre-emption: one that protects activities for National Labor Relations Board oversight and one that leaves some economic conduct free from regulation. The Court found that those doctrines limit state regulation, but not the State’s role as a market participant. Because Congress has long allowed prehire project labor agreements in the construction industry, the Court concluded MWRA acted as a purchaser, not as a regulator, and its bid specification was not preempted. The Court reversed the injunction that had blocked the rule.

Real world impact

The decision lets public agencies require valid project labor agreements in competitive bids and allows enforcement of such bid terms. Contractors who decline to accept those agreements may lose public contracts. The ruling reversed the preliminary court order and sent the case back for further proceedings consistent with this view.

Dissents or concurrances

Lower courts were divided; the Court of Appeals had a close 3–2 split, reflecting differing views on whether the agency’s action was regulation or proprietary purchasing.
