A federal judge is listening to arguments over the rule governing rallies at the Wisconsin Capitol.
The Walker Administration enacted the rule in late 2011, following weeks of massive demonstrations earlier in the year. Under the rule, groups that want to promote a cause at the Capitol, must obtain a permit, if the rally will involve four or more people.
Assistant Attorney General Maria Lazar told Judge William Conley that Capitol police need to know how many people are in the building.
ACLU Attorney Laurence Dupuis argued that the rule violates free speech rights. The ACLU has taken the matter to federal court.
