PORTLAND, Ore. — The small Oregon city at the heart of a major U.S. Supreme Court ruling last year that allowed cities across the country to enforce homeless camping bans is facing a fresh lawsuit over its camping rules, as advocates find new ways to challenge them in a legal landscape shifted by the high court's decision.

Just months after receiving national attention as the plaintiff of a Supreme Court case over its homeless policies, the small southern Oregon city of Grants Pass is being now accused of forcing hundreds of homeless people into one small campsite.
