ON CRIMES
Chapter 24 On General Grounds for Exemption from Criminal Responsibility
Section 4
An act by a person, in cases other than those described previously in this Chapter, if committed out of necessity, constitutes a crime only if it is indefensible having regard to the nature of the danger, the injury caused to another and to the circumstances in general.
Necessity exists when a danger threatens life, health, property or some other important interest protected by the law. (Law 1994:458)
