A lawsuit by American Civil Liberties Union lawsuit over traffic stops by U.S. Border Patrol agents on the Olympic Peninsula is moving forward.

Federal District Court Judge Benjamin Settle denied on Monday a motion by the government to dismiss the lawsuit.

In April, the ACLU and the Northwest Immigrant Rights Project sued the Border Patrol seeking to bar agents from making traffic stops, saying people are being pulled over and questioned for the way they look and without reasonable suspicion.

The lawsuit stems from tensions between immigrants and the expanded presence of Border Patrol agents on Washington state's Olympic Peninsula, which shares no land border with Canada.

In the lawsuit, the ACLU used three U.S. citizens who were stopped and questioned by agents.
