Case law on municipal liability
What is Municipal Liability?
Municipal liability arises when a municipality (city, town, county, etc.) is held responsible for constitutional violations or torts committed by its employees or officials. Unlike individual liability, municipalities can only be held liable if the injury results from an official policy, custom, or practice—not merely on a theory of respondeat superior (vicarious liability).
Key Case Laws on Municipal Liability
1. Monell v. Department of Social Services, 436 U.S. 658 (1978)
Significance: This is the landmark U.S. Supreme Court case that established municipal liability under Section 1983 of the Civil Rights Act for constitutional violations.
Facts: The plaintiff alleged that the New York City Department of Social Services had an unconstitutional policy that resulted in deprivation of her rights. She sued the municipality directly.
Holding: The Court held that municipalities are "persons" under Section 1983 and can be sued for constitutional violations only when the injury is caused by an official policy or custom of the municipality. Importantly, a municipality cannot be held liable under a respondeat superior theory just because it employs a tortfeasor.
Explanation: This case sets the foundation: to hold a municipality liable, plaintiffs must prove that the violation resulted from an official policy or widespread custom. Isolated actions of employees are not enough.
2. Board of County Commissioners v. Brown, 520 U.S. 397 (1997)
Significance: This case clarifies what counts as an official policy or custom for municipal liability.
Facts: The plaintiff was fired in violation of his constitutional rights and sued the county. The question was whether the county could be held liable under Section 1983.
Holding: The Court ruled that the county was liable because the unconstitutional act was taken by an official with final policymaking authority.
Explanation: This case emphasized that for municipal liability, it’s crucial to identify whether the official who acted has final policymaking authority on the issue. Actions by such officials are considered the municipality’s official policy.
3. City of Canton v. Harris, 489 U.S. 378 (1989)
Significance: This case established that failure to train municipal employees can be a basis for municipal liability.
Facts: A man died after inadequate medical treatment by city employees in jail. The plaintiff argued the city was liable for failing to properly train its staff.
Holding: The Court held a municipality could be liable if its failure to train amounts to "deliberate indifference" to the rights of persons with whom employees come into contact.
Explanation: Municipal liability can arise not only from explicit policies but also from failure to train employees when such failure shows deliberate indifference to constitutional rights.
4. Pembaur v. City of Cincinnati, 475 U.S. 469 (1986)
Significance: This case explains the importance of a single decision by a final policymaker.
Facts: Deputies entered a doctor’s clinic without proper legal authority based on the decision of the county prosecutor.
Holding: The Court held that a single decision by a final policymaker (here, the prosecutor acting in his official capacity) can establish municipal liability.
Explanation: This case highlights that municipal liability doesn’t require a formal written policy; a single, intentional decision by a person with final authority can suffice.
5. Jett v. Dallas Independent School District, 491 U.S. 701 (1989)
Significance: The case clarified that municipalities can be sued directly for violations under Section 1983, not just individual employees.
Facts: The plaintiff sued the school district for violating his constitutional rights by failing to prevent racial discrimination.
Holding: The Court reiterated that municipalities are liable under Section 1983 only if the violation was caused by an official policy or custom.
Explanation: This reinforces the Monell principle and confirms that municipalities, not just individual employees, can be held accountable for constitutional violations.
Summary
Municipal liability requires that a constitutional violation or injury be traceable to:
An official policy or formal ordinance (Monell),
A custom or widespread practice (Monell),
A decision by a final policymaker (Pembaur, Board of County Commissioners v. Brown),
Or failure to train with deliberate indifference (City of Canton v. Harris).
Municipalities are not liable for isolated acts of employees without these links.
