 The Black Heritage Society and Duncantell sued the city in 2007 after Duncantell did not get the permit, arguing that several provisions of the ordinance enforcing the one parade per day in Downtown rule were unconstitutional.In 2007 Lee Rosenthal, a U.S. district judge, on January 10, 2007, ordered the city government to allow both parades to hold their events in Downtown Houston.By 2008 the one parade per day rule, with the prized parade day decided by a coin toss, was again in place.
