According to this AP article, Groups Sue NYC Over Rally Permit Refusal, New York City has refused to issue a permit for the anti-war march United for Peace and Justice wants to hold on February 15, 2003.
Chris Dunn, a staff attorney for the New York Civil Liberties Union, who filed the lawsuit for the anti-war group, said the city had refused to permit a parade under any circumstances, citing concerns over congestion and related issues.
The court papers noted that the city routinely issues permits for large-scale marches in midtown Manhattan, including the St. Patrick's Day parade and the Thanksgiving Day parade.
Apparently the City wants a, "stationary rally on a plaza across the street from the United Nations."
