MBE Rules · Criminal Law

Voluntary manslaughter — heat of passion

The rule

Intentional killing mitigated from murder by (1) adequate provocation, (2) that would arouse sudden passion in a reasonable person, (3) defendant in fact so aroused, AND (4) no cooling-off period. Provocation must be from victim; words generally insufficient.

In plain English

Voluntary manslaughter happens when someone kills another person in a sudden, intense emotional state caused by something that would upset a reasonable person, and they didn't have time to calm down.

Worked example

The defendant finds their partner in bed with someone else and immediately attacks and kills the intruder. The intense shock and betrayal could reduce the charge to voluntary manslaughter since there was no time to cool off.

Memory hook

Heat of Passion: Hot, Not Cold. Sudden rage from provocation, no time to cool off.

The trap

Students think: Any provocation suffices. Wrong, because it must be adequate to a reasonable person. The actual test is the objective standard of adequate provocation.

How examiners test it

The MBE loves: a heated argument with mere insults. Trap: students assume insults qualify. Provocation must be adequate and sudden with no cooling-off.
