The State Milk Inspection Seal
State X enacted the Milk Safety Act. It requires every gallon of fluid milk sold at retail in State X to bear a State X inspection seal. The seal issues only after the milk is sampled at a State X-licensed laboratory and held in State X for 24 hours. State X producers already use State X labs and storage, so they face no new cost. Out-of-state dairies must ship milk to a State X transfer station, unload it, store it for 24 hours, and reload it. Dairy Y, a State Y cooperative, sells 40,000 gallons per month in State X and already meets federal Grade A pasteurization and testing standards. Compliance would require it to build or lease a transfer station in State X at an estimated cost of $600,000 and would add two days to delivery. State X defends the Act as a health measure; it introduced no evidence of any milk-safety problem linked to out-of-state milk. Dairy Y sues in federal court for injunctive relief.
1. Does the Act discriminate against interstate commerce under the dormant Commerce Clause? Explain.
Read the worked answer
Yes, at least in practical effect, and it likely fails. The Act is facially neutral: it applies to all milk sold in State X. But its design imposes new costs only on out-of-state dairies. In-state producers already use State X laboratories and storage, so they avoid the $600,000 transfer-station cost and the two-day delay. Out-of-state milk must be unloaded, stored, and reloaded in State X solely because of its origin. That is not even-handed treatment. A discriminatory state law faces strict scrutiny: the state must show a legitimate local purpose that cannot be served by reasonable nondiscriminatory alternatives. Health is legitimate, but State X introduced no evidence of a milk-safety problem tied to out-of-state milk, and Dairy Y already meets federal Grade A standards. State X could use random sampling, federal inspection records, or reciprocal inspection rather than a mandatory in-state facility. Even if a court treated the Act as nondiscriminatory, the Pike balancing test would likely invalidate it because the burden on interstate commerce is clearly excessive in relation to the local benefits shown.
2. Could State X defend the Act under the market-participant exception or as a quarantine law?
Read the worked answer
No on both theories. The market-participant exception applies when a state acts as a buyer or seller of goods or services, not when it regulates private sellers. State X is requiring private retailers and dairies to comply with an inspection seal; it is not purchasing milk or operating a state dairy. The quarantine or inspection exception is narrow: a state may exclude diseased or contaminated goods when it has a legitimate health basis, but it cannot discriminate merely because goods came from another state. State X has no evidence that out-of-state milk is unsafe, and Dairy Y already satisfies federal Grade A standards. The 24-hour storage and in-state laboratory requirements are not a genuine quarantine measure; they are a local-processing mandate. A health rationale must rest on actual risk and must use the least burdensome reasonable means. Because State X has offered no such evidence, neither exception saves the Act.
3. Does Dairy Y have Article III standing to challenge the Act?
Read the worked answer
Yes. Standing requires injury in fact, causation, and redressability. Dairy Y faces a concrete economic injury: it must spend an estimated $600,000 to build or lease a transfer station, and it faces a two-day delay that may cost sales. That is more than a generalized grievance; it is a direct compliance cost. The injury is fairly traceable to the Act because the seal, in-state laboratory, and 24-hour storage requirements cause the added cost. A favorable injunction would redress the injury by relieving Dairy Y of those requirements. Dairy Y also sells 40,000 gallons per month in State X, so it is directly regulated and has a concrete stake. It need not wait for a prosecution; the compliance burden is present and immediate. The association or cooperative form does not defeat standing if Dairy Y itself sells the milk and suffers the injury.
