Answer:
b. Gilleo, because the prohibition was overly broad.
Step-by-step explanation:
When a city government decides to make a ban, that ban must be formulated specifically, explaining well to the population what things are being banned. The prohibition should not be ambiguous, contradictory and broad, because this can cause confusion in citizens and disobedience to prohibition, so the prohibition must be clear, specific and concrete. An example of a vaguely formulated prohibition that led to its disobedience is the city of Ladue's prohibition on signs on the front lawns. The city established a very vague prohibition, which can cause confusion and led to disobedience of Gilleo.
For this reason, we can conclude that who is likely to win the lawsuit between the city x Gilleo is Gilleo, because the prohibition was too broad.
