The American Center for Law and Justice is trying to keep an Islamic mosque from being built near Ground Zero, the site of the Sept. 11, 2001 terror attacks on the World Trade Center Towers in New York City.

The Washington, D.C.-based ACLJ attorneys appeared before the New York State Supreme Court Tuesday, arguing the site is hallowed ground and not the place to build a mosque.

They also argued that the present building that occupies the site should be preserved.

Read the lawsuit filed against the City of New York and the complaint.

"This site, in the shadow of the Twin Towers where landing gear from one of the hijacked planes landed, is part of sacred, hallowed ground and not the place to build a mosque," said Brett Joshpe, counsel for the ACLJ.

"Attempting to do so deeply offends many Americans-including family and friends of the 9/11 victims-and is simply wrong," Joshpe added.

The group represents Tim Brown, a New York City firefighter who survived the 9/11 terrorist attacks.

The court is scheduled to render its decision in four weeks.
