Nebbia v. New York
The Court upheld a New York law letting a state milk board set minimum retail prices for milk, ruling that price controls on an ordinary business do not automatically violate the Constitution.
The decision rejected the idea that only businesses like railroads or utilities can have their prices regulated, opening the door for states to set prices in a much wider range of industries when they find it serves the public good.
“Price control, like any other form of regulation, is unconstitutional only if arbitrary, discriminatory, or demonstrably irrelevant to the policy the legislature is free to adopt, and hence an unnecessary and unwarranted interference with individual liberty.”
The majority's core standard for when government price controls violate due process.
How it got here: A New York trial court convicted Nebbia; the county court and New York Court of Appeals affirmed, and he appealed to the Supreme Court.
The Case in Depth
What happened
During the Great Depression, New York dairy farmers were selling milk for less than it cost to produce, threatening the state's dairy industry. New York created a Milk Control Board that set minimum and maximum milk prices. A Rochester grocer, Nebbia, sold milk below the board's fixed price and was convicted of violating the law.
The question before the Court
Could New York fix the minimum price a grocery store could charge customers for a quart of milk?
Why it matters
Grocers, dairy farmers, and other small business owners became subject to state price-setting even though their businesses were not utilities or monopolies. The ruling gave state legislatures broad room to regulate prices during economic emergencies, shaping how far governments could go in managing the economy for decades afterward.
What changes now
The ruling is a final decision on the merits, and Nebbia's conviction and fine stood. More broadly, the decision meant New York's milk price controls could continue to operate, and it gave other states and later courts a broader framework for evaluating economic regulations, moving away from a narrow list of businesses eligible for price control.
What this does not decide
The Court did not decide that all price regulation is automatically valid — it still required that any such law have a reasonable relationship to a legitimate public purpose and not be arbitrary or discriminatory. The ruling addressed this specific milk order, not price controls generally.
Concurrences and dissents
Dissent — Justice McReynolds
“If here we have an emergency sufficient to empower the Legislature to fix sales prices, then whenever there is too much or too little of an essential thing — whether of milk or grain or pork or coal or shoes or clothes — constitutional provisions may be declared inoperative”McReynolds warns that upholding the milk price law would let almost any economic hardship justify overriding constitutional rights.
Justice McReynolds argued the majority abandoned settled constitutional limits by letting the state fix prices in an ordinary private business with no public franchise or monopoly. He argued the law would not even achieve its stated goal of raising farm prices, since it only raised store prices to already-impoverished consumers while producer prices stayed unregulated. He warned that treating a temporary 'emergency' as justification for overriding constitutional rights invited unlimited government power, comparing it to the wartime abuses rejected in Ex parte Milligan, and would have reversed the conviction.
How the Court got there
The legal reasoning, step by step
- The Court explained that under the Fourteenth Amendment's due process clause, a law regulating property or business is valid so long as it is not unreasonable, arbitrary, or capricious, and the means chosen have a real connection to a legitimate goal.
- The Court rejected the argument that price-fixing is only allowed for businesses 'affected with a public interest' like utilities or monopolies, explaining that this phrase means nothing more than that a business is subject to regulation for the public good when circumstances justify it.
- Applying that standard, the Court reviewed the extensive legislative investigation into New York's dairy industry, which found destructive price-cutting and other practices harming both farmers and the milk supply.
- The Court found the milk industry's instability and importance to public health gave New York good reason to conclude that ordinary competition alone could not fix the problem, justifying direct regulation of prices as well as other aspects of the business.
- Because the price-fixing order bore a reasonable relation to the goal of stabilizing the milk market and was not shown to be arbitrary or discriminatory, the Court concluded it satisfied the due process clause.
