What it's about

The Supreme Court ruled that this requirement applies even when people seek non-money relief, overturned the Ninth Circuit’s ruling, and sent the case back to the lower court (remanded).

The dispute was whether the rules for suing a local government change when a person asks for a court order instead of money.

Question presented

Are claims for declaratory relief against a local public entity subject to the requirement of Monell that the plaintiff must demonstrate that the constitutional violation was the result of the policy, custom, or practice attributable to the local public entity; or are such claims exempt as determined by the Ninth Circuit?

What the Court decided

Holding

Monell’ s “policy or custom” requirement applies in §1983 cases irrespective of whether the relief sought is monetary or prospective. Reversed and remanded.

Result
Reversed

The Court's reasoning

The Court said the policy-or-custom rule applies in federal civil-rights cases whether a person seeks money or a forward-looking court order.

The vote

Majority author
Stephen G. Breyer

What's next

The case goes back to the Ninth Circuit for further proceedings under the Supreme Court’s ruling.
