Coppage v. Kansas

236 U.S. 1 (1915)

Quick Summary

Coppage (defendant) an employer who mandated anti-union contracts, and the State of Kansas (plaintiff), which had outlawed such requirements. The dispute arose when Coppage fired an employee for refusing to leave his union.

The issue before the U.S. Supreme Court was whether this Kansas law infringed upon the due process clause of the Fourteenth Amendment. The Court ultimately determined that it did and overturned Coppage’s conviction for violating the state law.

Facts of the Case

In 1903, Kansas passed a law prohibiting employers from demanding that employees avoid joining labor unions as a condition of their employment. Coppage (defendant), a Kansas employer, defied this law by requiring his employees to sign contracts agreeing not to join unions, resulting in a fine from the State of Kansas (plaintiff).

The Supreme Court of Kansas upheld the conviction, leading to an appeal to the United States Supreme Court. The case centered around an incident where Coppage, as a superintendent for the St. Louis & San Francisco Railway Company, presented an employee named Hedges with an ultimatum: sign a contract to withdraw from the Switchmen’s Union or face termination. Hedges refused and was subsequently fired.

Procedural Posture and History

  1. Coppage required his employee Hedges to sign an anti-union contract as a condition of employment.
  2. Hedges refused and was fired, leading to Coppage’s conviction under Kansas law.
  3. The Supreme Court of Kansas affirmed the conviction.
  4. Coppage appealed to the United States Supreme Court on Fourteenth Amendment grounds.

I.R.A.C. Format


Whether the Kansas statute prohibiting employers from requiring employees to abstain from joining labor unions as a condition of employment violates the Fourteenth Amendment’s due process clause.

Rule of Law

The right to make contracts, including employment contracts, is a fundamental liberty protected by the Fourteenth Amendment, and any state interference with this right must be reasonable and not arbitrary.

Reasoning and Analysis

The U.S. Supreme Court analyzed the case in light of the Fourteenth Amendment and previous rulings, notably Adair v. United States. It determined that if Congress cannot interfere with an employer’s right to hire and fire based on union membership due to the Fifth Amendment, then states cannot do so either under the Fourteenth Amendment.

The Court emphasized that both parties in an employment contract must be free to establish the terms of employment without undue state interference.

Furthermore, the Court argued that what an employer regards as sufficient grounds for terminating employment should be equally valid grounds for setting initial employment terms. It concluded that the Kansas statute, as applied in this case, did not serve any legitimate police power interest and was thus an unconstitutional restriction on the freedom of contract.


The U.S. Supreme Court reversed the decision of the Supreme Court of Kansas, holding that the Kansas statute was unconstitutional as it violated the Fourteenth Amendment by unduly infringing on the right of contract and liberty of both employers and employees.

Key Takeaways

  1. The freedom to make employment contracts is a protected liberty under the Fourteenth Amendment.
  2. State laws that arbitrarily interfere with the right to make contracts may be deemed unconstitutional.
  3. The case reaffirmed that both employers and employees have equal rights in determining employment conditions without undue state restrictions.

Relevant FAQs of this case

What legal principles determine the balance between an individual's liberty to enter into contracts and state regulation for public welfare?

An individual’s liberty to contract is circumscribed by the state’s police power, which allows for regulation in the interest of public health, safety, welfare, and morals. The court often uses the ‘rational basis test’ to determine if the state’s regulation serves a legitimate public interest and whether the means chosen to regulate are not arbitrary or discriminatory.

  • For example: A law mandating safety equipment for construction workers may be upheld because it reasonably relates to worker safety, despite imposing restrictions on the employer’s freedom to contract.

How does a court distinguish between permissible and impermissible restrictions on the freedom of contract?

Courts look at the nature of the contractual term being restricted and the government’s purpose for the restriction. If a restriction serves a significant and legitimate public interest without being overly broad or vague, it is likely to be considered permissible.

  • For example: Restricting contracts that impose severe underpayment for services might be permissible to prevent exploitation and ensure fair wages.

What are the potential justifications for a government to interfere with employment contracts, and how might this be constitutionally challenged?

A government might justify interference on grounds of protecting workers’ rights, maintaining labor standards, or supporting collective bargaining. Such interference can be constitutionally challenged if it violates substantive due process rights under the Fourteenth Amendment by failing the test of ‘reasonableness’ or lacking proper authority.

  • For example: A minimum wage law could be justified to ensure a living wage but might be challenged if set at a level causing widespread unemployment due to undue burden on employers.
