Martin v. Boise (full case name Robert Martin, Lawrence Lee Smith, Robert Anderson, Janet F. Bell, Pamela S. Hawkes, and Basil E. Humphrey v. City of Boise) was a 2018 decision by the U.S. Court of Appeals for the Ninth Circuit regarding anti-camping ordinances targeting homeless people, effectively overturned by the U.S. Supreme Court in 2024.

In 2019, the U.S. Supreme Court declined to hear an appeal of the case, leaving the precedent intact in the nine Western states under the jurisdiction of the Ninth Circuit (Alaska, Arizona, California, Hawaii, Idaho, Montana, Nevada, Oregon, and Washington),[4] but in 2024, the Supreme Court effectively overturned Martin v. Boise in its City of Grants Pass v. Johnson decision denying the extension of cruel and unusual punishment to anti-camping ordinances.

In 2009, after a local homeless shelter in Boise closed, six people were cited for violations of a city ordinance that made it illegal to sleep on public property.

[1] The Ninth Circuit Court of Appeals' decision striking down anti-camping ordinances when applied to homeless individuals still allowed state and local governments to enact time, place, and manner restrictions on the population's ability to camp on public land.
