Lawyers challenging Arizona's 2010 immigration law, SB 1070, urged the U.S. Supreme Court on Monday to reject Gov. Jan Brewer's request for the court to review a ruling that prevents enforcement of a minor section of the law.

Brewer is trying to get the nation's highest court to review an October decision by the 9th Circuit Court of Appeals that blocks the law's prohibition on harboring people whose presence in the United States isn't authorized.

The appeals court found the harboring ban was vague and trumped by federal law.

Brewer's attorneys say the appeals court decision was flawed and are contesting the legal standing of those challenging the ban.

The lawyers pushing the challenge say none of the country's federal appeals courts have upheld similar state laws in other states.
