Immunity for government-hired lawyers

Updated Oct 18, 2026

What it's about

The Supreme Court unanimously overturned the Ninth Circuit’s ruling that Filarsky’s private status alone barred him from seeking that defense, but did not decide whether he ultimately qualified for it.

Rialto hired Filarsky, a private lawyer, to investigate firefighter Nicholas Delia. Delia later sued over alleged constitutional violations during the investigation.

Qualified immunity is a defense in personal damages suits over government work; the dispute was whether a city’s outside lawyer could seek it.

Question presented

If a private lawyer is retained by the government, is that attorney precluded from claiming qualified immunity solely because he or she is a private lawyer rather than a government employee?

What the Court decided

Holding

A private individual temporarily retained by the government to carry out its work is entitled to seek qualified immunity from suit under §1983. Pp. 4 − 16. 621 F. 3d 1069, reversed.

Result
Reversed

The Court's reasoning

The Court said that not being a government employee does not by itself prevent a private person temporarily hired to do government work from seeking the defense.

The vote

Majority author
John G. Roberts, Jr.

What's next

Further proceedings may address whether Filarsky meets the usual test for qualified immunity; the Supreme Court left that question open.
