## Facts

- New Orleans experienced serious disease outbreaks after its water supply was polluted by refuse from slaughterhouses operating in and around the city.
- To address sanitation and public-health problems, the Louisiana legislature chose to concentrate slaughtering activity at a single location away from the city’s water supply.
- In 1869, Louisiana enacted a statute creating the Crescent City Livestock Landing & Slaughter-house Co. (Crescent City) and granted it exclusive rights over slaughtering operations in the New Orleans area.
- The statute required Crescent City to construct and operate slaughtering and landing facilities at the designated site.
- Local butchers were not barred from working as butchers, but they were required to slaughter livestock at Crescent City’s facilities and pay regulated fees for use of the premises and services.
- The Butchers’ Benevolent Association of New Orleans and other affected butchers sued Crescent City, arguing the monopoly and compulsory-use requirement harmed their livelihoods and forced them to conduct their trade on Crescent City’s terms.
- The butchers alleged the statute violated the Thirteenth Amendment (by imposing involuntary servitude) and the Fourteenth Amendment’s Privileges or Immunities, Due Process, and Equal Protection Clauses.
- The Louisiana Supreme Court ruled for Crescent City. Multiple related cases were reviewed together by the U.S. Supreme Court, which granted review and issued a single consolidated decision.

## Issues

1. Whether Louisiana’s exclusive slaughterhouse franchise and mandatory use of Crescent City’s facilities imposed “involuntary servitude” in violation of the Thirteenth Amendment.
2. Whether the statute abridged the “privileges or immunities of citizens of the United States” under the Fourteenth Amendment by interfering with the butchers’ claimed right to pursue their occupation free from state interference.
3. Whether the statute violated the Fourteenth Amendment’s Due Process Clause by depriving the butchers of liberty or property through economic regulation and a state-created monopoly.
4. Whether the statute denied equal protection of the laws in violation of the Fourteenth Amendment.

## Decision

- The U.S. Supreme Court affirmed the Louisiana Supreme Court (5–4) and upheld the statute.
- The Court held the Thirteenth Amendment did not apply because the challenged law was an economic and health regulation, not slavery or involuntary servitude as understood by the Amendment.
- The Court interpreted the Fourteenth Amendment’s Privileges or Immunities Clause narrowly, concluding it protects only a limited set of rights tied to national (federal) citizenship, not the general civil rights associated with state citizenship, such as an asserted right to pursue a trade free from state regulation.
- The Court rejected the Due Process and Equal Protection challenges, treating the statute as a legitimate public-health measure within the state’s police power; the butchers could continue working, but must do so at the centralized facility and pay the prescribed charges.
- Justice Miller authored the majority opinion. Chief Justice Chase and Justices Field, Swayne, and Bradley dissented, with Justice Field arguing the Privileges or Immunities Clause should protect the right to pursue a lawful calling.

## Legal Principles

- The Thirteenth Amendment prohibits slavery and conditions comparable to compelled labor; it does not convert ordinary occupational regulation or a state-granted franchise into “involuntary servitude.”
- The Fourteenth Amendment Privileges or Immunities Clause protects only privileges of U.S. (national) citizenship—rights that owe their existence to the federal government, the U.S. Constitution, or federal law—and does not constitutionalize broad economic liberty against state regulation.
- States retain broad police power to enact health and sanitation regulations affecting businesses and occupations, including concentrating hazardous activities in a designated place, so long as the regulated activity remains lawful subject to reasonable conditions.
- The Equal Protection and Due Process Clauses, as applied in this decision, did not invalidate a race-neutral economic regulation that allowed continued participation in the trade on payment of set fees and compliance with the statutory scheme.
- The decision reflects the Court’s view that the Reconstruction Amendments were chiefly aimed at securing freedom and legal equality for formerly enslaved people and were not intended to transfer general oversight of ordinary state economic regulation to the federal courts.

## Conclusion

In the Slaughter House Cases, the Supreme Court upheld Louisiana’s centralized slaughtering scheme as a valid health measure and rejected constitutional attacks under the Thirteenth and Fourteenth Amendments. The Court’s narrow reading of the Privileges or Immunities Clause confined it to a limited category of rights tied to national citizenship, leaving most protections for occupational freedom and ordinary civil rights to state law and state institutions, subject to only limited federal constitutional review in this context.
