The city of San Francisco is considering a lawsuit against Nevada for allegedly releasing and providing hundreds of psychiatric patients one-way bus tickets into California, KTVU reports.

The possible action stems from a separate federal civil rights suit filed by James Flavey Coy Brown in Nevada, who alleges the state put him on a one-way bus to northern California after discharging him from a treatment facility. He’s seeking class-action status for as many as 1,500 others.
