As the U.S. Supreme Court heard arguments Monday about whether cities can fine or arrest homeless people for sleeping outside, advocates of homeless people rallied in Newark against those kinds of laws.

The Supreme Court is wrestling with a set of Oregon laws that ban camping on public property like streets and sidewalks when there aren’t enough beds in homeless shelters. The case was brought by two homeless people arguing that removing, fining or arresting homeless individuals from public spaces was a form of “cruel or unusual punishment” and violates the Constitution’s Eighth Amendment.

“The outcome will determine whether the United States will be a country that fines or arrests people for experiencing homelessness, or a country that invests in solutions,” said Richard Uniacke, president of the nonprofit Bridges Outreach. Uniacke and other advocates spoke at a rally in Harriet Tubman Square in Newark, a city that has greatly reduced homelessness, according to state data, without fining or arresting people.

“This is a city that has seen a reduction in unsheltered homelessness of 57.6% because of the work that is being done in Newark,” said Uniacke.
