Defences - Defence of Property
A person is entitled to use such conduct as he or she genuinely believes is necessary to defend property from being taken, destroyed, damaged or interfered with; to prevent criminal trespass; or to arrest someone unlawfully at large - as long as the conduct was reasonably proportionate to the threat the defendant genuinely believed to exist (see also: Home invasion), and if the conduct resulted in death, the defendant did not act recklessly or intend to cause death.
