LOS ANGELES (CNS) - A civil rights group sued the Los Angeles County  Board of Supervisors today, challenging the constitutionality of the panel's  recent decision to restore a cross to the county seal.

The complaint filed in federal court by the American Civil Liberties  Union of Southern California contends that restoring the cross was  unconstitutional because it ``favors the Christian religion over all other  religions and divides County residents by religion and by adherence or non- adherence to religious beliefs.''

In a motion introduced by Supervisors Mike Antonovich and Don Knabe, the  board voted 3-2 last month to add a cross to the top of the San Gabriel  Mission in its depiction on the county emblem, which is displayed on buildings,  vehicles and official communications.

Antonovich and Knabe argued that restoring the cross is vital to the  historical accuracy of the seal.

Mark Rosenbaum, chief counsel of the ACLU/SoCal, responded that the two  supervisors ``are historians in the same way SNL's Father Guido Sarducci is a  priest. These supervisors have exacerbated the constitutional slap at all  religions by reinserting a Christian cross on the seal by means of a Pinocchio- style fib.''

Knabe called the lawsuit ``frivolous'' and said the motion to ``update''  the seal ``was in the name of historical correctness, not political  correctness.''

``While the ACLU has chosen to engage in this issue, today I am up in  Sacramento working with a bipartisan group of elected officials to protect our  most vulnerable, the young victims of sexual exploitation and trafficking,''  the supervisor said.

Antonovich said the lawsuit represented the latest attempt by ``ACLU  storm troopers'' to ``rewrite history,'' but promised that ``just as other  California municipalities have missions on their seals, Los Angeles County will  prevail.''

He said the board's restoration of the cross last month results in ``an  accurate rendering of the current mission.''

But the ACLU contends that historical accuracy ``does not trump the  Constitution.''

'`In choosing to place a symbol of Christianity on the official seal,  which appears on county vehicles, meeting rooms and elsewhere, the supervisors  have chosen to violate the U.S. Constitution's Establishment Clause that  guarantees the separation of church and state,'' according to the ACLU.

``By elevating the symbol of one faith over all others, the supervisors  fail to protect the rights of all religions,'' Rosenbaum said. ``That's simply  un-American.''
