from game commission web site : Hunting for or disturbing game, or discharging firearms within 150 yards of occupied dwellings or other farm buildings is unlawful except by specific permission of the landowner or tenant. The cooperating farmer erects Safety Zone posters which are supplied free of charge by the Game Commission, through the local Wildlife Conservation Officer (WCO). These signs must be erected not more than 150 yards from farm buildings. The penalty for violating the Safety Zone Law is determined by the magistrate and includes costs of prosecution.

so...where are the rules saying what the magistrate can decide is the "penalty"...
