Ex Parte Young

The railroad's claim that the state-prescribed rates were confiscatory invoked the Fourteenth Amendment's protection against deprivation of property without due process of law. Although deciding that claim required detailed factual inquiry into revenues, costs, and the adequacy of the rates, the constitutional sufficiency of rates was a judicial question arising under federal law.

The complaint also alleged that the extraordinary fines and criminal sanctions effectively denied the company a meaningful opportunity to seek judicial review, and that the laws interfered with interstate commerce. Those were not frivolous constitutional claims. Diversity jurisdiction was absent, but federal-question jurisdiction was sufficient.

The freight law exposed officers, agents, and employees to repeated fines and jail terms, while the passenger law made each sale of an above-rate ticket a felony punishable by up to five years' imprisonment and a substantial fine. The company itself also faced major financial penalties for violating commission orders.

To obtain review under the State's scheme, the railroad would have to induce an employee to violate the law and risk criminal punishment if the challenge failed. The practical effect was to compel obedience even if obedience itself would confiscate property, rather than permit a genuine judicial determination of whether the rates were constitutional.

A State may impose penalties to secure compliance with valid laws. But it may not impose penalties so severe, before the validity of a law can be tested, that affected parties must abandon their constitutional challenge. That indirect denial of access to the courts is constitutionally equivalent to making the legislature's or commission's rate determination conclusive.

The validity of a rate schedule depended on complicated factual questions, including the carrier's costs, earnings, investment, and the allocation of intrastate and interstate business. Those questions were unsuitable for a practical and adequate resolution through a single criminal prosecution, penalty action, or jury trial.

Waiting for the State to bring an enforcement action would force the railroad and its employees to risk enormous fines and imprisonment. Even if the railroad ultimately prevailed, it could not recover property lost during the years required for litigation. Thus, the ordinary legal remedies were not plain, adequate, or complete.

A comprehensive equity suit allowed all directly interested parties to be heard and allowed a court to determine the constitutional question before enforcement caused irreparable injury. The rate laws remained presumptively valid, and the railroad bore the burden of proving confiscation, but equity supplied the appropriate procedure for making that showing.

When a state official seeks to enforce a statute that conflicts with the Federal Constitution, the official acts without lawful authority. Because the Constitution is supreme, the officer is stripped of the State's representative character for purposes of that unconstitutional conduct and may be restrained in an individual capacity.

The rule does not permit a plaintiff to sue any state official merely because of that official's general position. The officer must have some connection with enforcement of the challenged law. That connection may arise from general state-law duties rather than from an express enforcement provision in the challenged statute itself.

Young had the necessary connection. Under Minnesota law and his common-law and statutory powers, he could institute proceedings to enforce state laws and acted as counsel for the railroad commission. His prompt filing of the mandamus action confirmed that he regarded enforcement of the rate law as within his official authority.

The injunction did not compel Minnesota to perform a contract, require payment from the state treasury, or otherwise operate directly against the State as the real party in interest. It prohibited Young from using state authority to enforce a law alleged, and preliminarily found, to violate the Federal Constitution.

Equity generally does not interfere with state criminal proceedings. But an exception applies when an officer who is already a party to a pending federal equity suit threatens proceedings to enforce the very statute whose validity is before the federal court, and those proceedings threaten irreparable injury to property rights.

The federal injunction ran against Young personally, not against Minnesota courts or grand juries. State courts remained free to act in cases brought before them, and grand juries remained free to investigate. If Young violated the injunction by initiating a proceeding, his contempt was personal; the state tribunal itself was not restrained or punished.

Restraining Young from enforcing an unconstitutional statute did not improperly control his prosecutorial discretion. The order did not direct affirmative official action; it merely prohibited action that, if the statute were unconstitutional, he had no legal right to take.
