Economic favoritism by which a state shields its residents from out-of-state competition through discriminatory regulations or barriers on interstate commerce. Such measures trigger strict scrutiny under the Dormant Commerce Clause and are presumptively invalid when they lack a nonprotectionist justification.
Pavel Petrov operates a bait shop in State A and purchases live baitfish from State B suppliers. State B enacts a statute that prohibits any export of the fish to out-of-state buyers. Petrov cannot obtain his usual supply and loses sales. The ban prevents interstate movement solely to reserve the resource for in-state purchasers.
Pulse Media generates solid waste at its printing facility in State C. A municipal ordinance requires all local waste to be processed at a designated in-state plant before any shipment elsewhere. Pulse Media must pay higher fees and cannot use a lower-cost out-of-state processor. The rule blocks access to interstate waste markets.

Preston Pratt owns an out-of-state winery that seeks to ship directly to consumers in State D. State D permits in-state wineries to make such shipments but denies the same right to out-of-state producers. Pratt loses direct sales and must route product through in-state distributors. The distinction reserves market access for local wineries.
Precision Tools disposes of industrial waste generated at its plant in State E. A county ordinance directs all commercial waste to a newly created public authority facility and bars contracts with private or out-of-state processors. Precision Tools must pay the authority's rates even though cheaper private options exist. The measure favors the government-owned site over interstate competitors but receives lenient review as likely motivated by legitimate public objectives.
Pedro Pacheco owns a landfill in State F that accepts solid waste from neighboring states. State F enacts a statute that forbids private landfills from receiving any out-of-state garbage. Pacheco loses a major revenue stream and must turn away interstate haulers. The prohibition blocks importation to protect local disposal capacity.
Philip Powell is a qualified attorney licensed in State G who seeks admission on motion in State H. State H's bar rule grants admission without examination only to residents of State H. Powell maintains his practice and residence in State G and is denied admission solely on that basis. The residency rule reserves professional opportunity for local lawyers under the Privileges and Immunities Clause.
A state measure constitutes impermissible economic protectionism when it discriminates against interstate commerce to favor in-state economic interests over out-of-state competitors. Courts apply a virtually per se rule of invalidity to such laws. The measure is invalid unless the state demonstrates a legitimate non-economic purpose and the absence of reasonable nondiscriminatory alternatives.

The market participant doctrine permits a state to favor its own citizens when the state acts as a buyer or seller in the market rather than as a regulator. Such proprietary actions do not trigger strict Dormant Commerce Clause scrutiny. When the state imposes downstream conditions or regulates the broader market, the protectionist character reappears and the measure loses the doctrine's protection.

The Twenty-First Amendment does not shield state liquor laws from Dormant Commerce Clause review when those laws discriminate against out-of-state producers. A state may not allow in-state wineries to ship directly to consumers while denying the same right to out-of-state wineries. Such discrimination remains subject to invalidation as economic protectionism.
