Rudy Giuliani, when mayor of NYC, passed a law that said if a person?
Mayors dont pass laws. City councils pass ordinances and laws. The mayor will suggest that a certain law or action be taken but the council has to approve whatever action is approved. Larger cities like New York and Chicago pass laws because of their sizes and population amount. Laws that are passed can be overturned by the courts if they feel such laws are unjust or illegally applied.
