federal court on Tuesday issued a preliminary injunction forbidding the Border Patrol from conducting warrantless immigration stops throughout a wide swath of California.

The ruling came in response to an American Civil Liberties Union lawsuit filed after the El Centro Border Patrol traveled to Kern County to conduct a three-day sweep in January, detaining day laborers, farm workers and others in a Home Depot parking lot, outside a convenience store and along a highway between orchards.
