The negative Commerce Clause
Even without congressional action, the Commerce Clause implicitly restricts states from discriminating against or unduly burdening interstate commerce. This "dormant" or "negative" aspect of the Commerce Clause prevents states from engaging in economic protectionism.
Two tiers of scrutiny
Discriminatory state laws (those that facially discriminate or have discriminatory purpose/effect against interstate commerce) are virtually per se invalid unless the state can show the law serves a legitimate local purpose that cannot be served by nondiscriminatory alternatives. Nondiscriminatory laws that incidentally burden interstate commerce are evaluated under Pike balancing.
Exceptions
Congressional authorization: Congress can consent to state regulations that would otherwise violate the DCC. Market participant doctrine: When a state acts as a market participant rather than a regulator, it is not subject to DCC constraints.
Congressional authorization
Congress can authorize state laws that would otherwise violate the DCC. When Congress speaks, the dormant Commerce Clause is irrelevant — the question becomes whether the federal statute validly authorizes the state action.
Discrimination analysis
A state law discriminates if it (1) facially distinguishes between in-state and out-of-state economic interests, (2) has a discriminatory purpose, or (3) has a discriminatory effect. Examples: banning importation of out-of-state waste, requiring in-state processing, or giving preferences to local businesses.
Virtually per se invalid (strict scrutiny)
Discriminatory laws are presumptively unconstitutional. The state must demonstrate that the law serves a legitimate local purpose AND that purpose cannot be served adequately by reasonable nondiscriminatory alternatives. This burden is almost never met.
Pike balancing (intermediate scrutiny)
"Where the statute regulates even-handedly to effectuate a legitimate local public interest, and its effects on interstate commerce are only incidental, it will be upheld unless the burden imposed on such commerce is clearly excessive in relation to the putative local benefits" (Pike v. Bruce Church). Balances local benefits against interstate commerce burden.
Market participant doctrine
When a state enters the market as a buyer, seller, or subsidizer (rather than regulating private parties), the DCC does not apply. The state is free to favor its own residents, e.g., by selling state-produced cement only to in-state buyers (Reeves v. Stake) or by hiring only state residents for state construction projects (White v. Massachusetts Council). But the doctrine does not extend to downstream restrictions on how buyers use what they purchased from the state (South-Central Timber v. Wunnicke).
