Definition and Basic Elements
In Austrian law, manslaughter (Totschlag) is defined under Section 75 of the Criminal Code as the unlawful killing of another person without the specific premeditation and deliberation that characterizes murder. The prosecution must prove three core elements: first, that the defendant caused the death of another human being; second, that the defendant acted unlawfully; and third, that the defendant did not act with the calm reflection and prior planning required for murder.
Unlawful Killing
The killing must be unlawful, meaning it was not legally justified or excused. Self-defense, defense of others, or necessity can provide legal justification. The killing can result from direct action or from creating a dangerous situation that leads to death. The unlawfulness is evaluated based on whether the defendant violated the legal right to life of the victim.
Causation and Mens Rea
The defendant's conduct must have directly caused the victim's death through a chain of causation with no intervening acts that break the connection. Austrian law requires either intent (meaning the defendant wanted the death to occur) or recklessness (meaning the defendant knowingly took a serious risk of causing death). Simple negligence is generally not sufficient for manslaughter; the defendant must have acted with awareness of the danger.
Distinction from Murder
The critical difference between manslaughter and murder (Mord, Section 75a) in Austrian law is the absence of Überlegung (calm reflection) and Bedacht (deliberation). Murder requires that the perpetrator had time to consider their actions beforehand and acted with conscious intent after such reflection. Manslaughter occurs when the killing happens in the heat of the moment, in a sudden rage, or without the defendant having planned or deliberately thought through the act beforehand.
Burden of Proof
The prosecution must prove all elements of manslaughter beyond a reasonable doubt. The defendant can offer evidence of provocation, diminished capacity, or other mitigating circumstances that may reduce the charge or sentence. The absence of premeditation and deliberation must be established in the specific facts of the case.
