But law enforcement officials said that a state may work with the federal government if they want, Molly Line reported.

The Justice Department, siding with state authorities, said any constitutional questions regarding states being banned from working with federal officials are unfounded.

Before court adjourned for the day in Boston, lawyers for the plaintiff, Cambodian refugee Sreynuon Lunn, said there is no implicit authority for state officials to make "warrantless" arrests for a civil violation.

Lunn's case is being closely followed by advocates on both sides of the national debate.
