An April 2 hearing has been set by an appeals court to hear arguments in Arizona Gov. Jan Brewer's bid to overturn a ruling that bars enforcement of a minor section of the state's 2010 immigration law.

Brewer's lawyers told the 9th Circuit Court of Appeals that a ban on harboring illegal immigrants is aimed at confronting crime, doesn't conflict with federal policies and that the law's opponents haven't shown they have legal standing to challenge the prohibition.

A coalition of civil rights groups that has challenged the law says the ban is trumped by a federal harboring law.

The harboring ban was in effect from late July 2010 until a federal judge blocked its enforcement last September as part of the coalition's challenge.
