SPOKANE, WA (AP) – The American Civil Liberties Union has sued the city of Spokane, alleging that its anti-camping laws violate the state constitution.

The complaint filed in Spokane County Superior Court challenges city ordinances that make camping, sitting or lying on public property misdemeanor crimes in certain circumstances.

Two of the plaintiffs are a homeless person and someone formerly homeless who were cited by police under Spokane’s ordinances.

One of its ordinances prohibits camping at all times, regardless of shelter availability, within 50 feet of a railroad viaduct located downtown or within three blocks of a homeless shelter. Another ordinance bars sitting or lying on the sidewalk in the downtown area between 6 a.m. and midnight.

Voters in November approved a ban on camping within 1,000 feet of a school, day care or park.

So far this year, the city has prosecuted at least 114 cases of unlawful camping and sitting and lying violations, according to the complaint.

It is believed to be the country’s first such legal challenge since the U.S. Supreme Court ruled in June that cities can enforce outdoor sleeping bans.

Last year, Washington had the fourth largest homeless population with more than 28,000 homeless residents.

Whatcom County’s Point In Time count from earlier this year reported over 1000 unhoused individuals.
