<P> German law allows self - defense against an unlawful attack . If there is no other possibility for defense, it is generally allowed to use even deadly force without a duty to retreat . However, there must not be an extreme imbalance ("extremes Missverhältnis") between the defended right and the chosen method of defense . In particular, in case firearms are used, a warning shot must be given when defending a solely material asset . Nevertheless, due to the low circulation of firearms in Germany the impact of this law is not all that strong . </P> <P> Under the terms of the Defence and the Dwelling Act, property owners or residents are entitled to defend themselves with force, up to and including lethal force . Any individual who uses force against a trespasser is not guilty of an offense if he or she honestly believes they were there to commit a criminal act and a threat to life . However, there is a further provision which requires that the reaction to the intruder is such that another reasonable person in the same circumstances would likely employ it . This provision acts as a safeguard against grossly disproportionate use of force, while still allowing a person to use force in nearly all circumstances . </P> <P> The law was introduced in response to DPP v. Padraig Nally . </P> <P> A person who uses such force as is permitted by section 2 in the circumstances referred to in that section shall not be liable in tort with respect to any injury, loss or damage arising from the use of such force . </P>
