Whether Boston’s 50% resident-hiring requirement violated the dormant Commerce Clause when applied to construction projects funded entirely with city money.
Holding
No. When Boston spent its own money on public construction contracts, it acted as a market participant and could favor Boston residents without violating the dormant Commerce Clause.
Reasoning
The Court reaffirmed the market-participant doctrine of Hughes v. Alexandria Scrap Corp. and Reeves, Inc. v. Stake. The dormant Commerce Clause principally restrains state taxes and regulations that burden private interstate trade; it does not ordinarily prevent a state or locality from acting as a buyer or seller in the market and favoring its own residents.
Boston was participating directly in the construction market when it financed public projects with city funds and attached a resident-workforce condition to its contracts. The relevant inquiry was whether the city directly participated in the market, not whether the policy had a substantial effect on out-of-state firms or workers.
The state court’s concerns about the order’s practical burden on interstate commerce and its breadth would matter if Boston were regulating the market. They did not determine whether Boston was instead acting proprietarily. Once Boston qualified as a market participant, the Commerce Clause did not require an independent justification for the local preference.
The Court acknowledged that a government cannot necessarily use its contracts to impose restrictions reaching far beyond the parties with which it deals. But this order covered a discrete and identifiable class of construction activity in which Boston was a major participant. Those working on the covered projects were, in a substantial practical sense, working for the city, so the order remained within the market-participant doctrine.
The Court confined its decision to the record. Although the order’s language could reach projects financed partly with private money, the parties had supplied no evidence that such mixed private-city projects had actually been subjected to the order.
