The following laws have been recently updated:
Any person may use a justifiable amount of force proportionate to a threat if they reasonably believe that such force would prevent great bodily harm or death.
If a person reasonably believes that acting in a way contrary to any law, with the exception of 9.5, is necessary to prevent injury or the loss of property they do not act unlawfully given that their actions are justifiable and proportionate.
Emergency Service workers may enter any private property if it is necessary for the execution of their duties. Emergency Service workers may not remain on a Private Property if asked to leave by the property owner unless this would obstruct an investigation into a criminal offence or the prevention of serious harm to or death of any person. Any Emergency Service worker who fails to do so commits the offence of trespassing.
