Written by attorneys · grounded in primary & secondary sources — see below
A doctrine in criminal law mitigating an intentional killing from murder to voluntary manslaughter when the defendant acts in the heat of passion upon adequate provocation before a reasonable cooling-off period has elapsed. Adequate provocation must be of a type that would arouse sudden intense passion in an ordinary person, the defendant must actually have been provoked, and the killing must occur before passion cools.

Darrell Duncan returns home early and finds his wife in bed with another man. Overcome by sudden rage, he immediately grabs a nearby object and strikes the man fatally. The discovery of adultery supplies adequate provocation under the doctrine, so the killing is reduced from murder to voluntary manslaughter.
Delilah Duran insults Diane Dawson during an argument and Dawson responds by shoving Duran to the ground, causing injury. Duran sues for battery.

Diane Dawson catches her spouse in adultery and immediately drives to confront the lover. Still visibly agitated upon arrival she kills the lover. Because she did not in fact cool off, the doctrine reduces the offense to voluntary manslaughter.
Certain situations qualify as adequate provocation, including a serious battery inflicted on the defendant or a close relative and catching one’s spouse in the act of adultery. Courts most frequently recognize adequate provocation in situations where the defendant suffers a serious battery, faces a threat of deadly force, or discovers a spouse engaged in sexual relations with another person.

Mere words, trivial battery, and provocation based on wrongs that occurred long in the past are legally inadequate and do not reduce murder to voluntary manslaughter.

The provocation must be of a kind that would cause an ordinary person to experience a sudden and intense passion sufficient to overwhelm self-control. The defendant must in fact have experienced such provoked passion at the time of the killing. There must not have been sufficient time between the provocation and the killing for a reasonable person’s passion to cool. The defendant must in fact not have cooled off between the provocation and the killing.

Discovery of a spouse engaged in sexual relations supplies the classic instance of adequate provocation. However, if sufficient time passes for a reasonable person to cool, or if the defendant in fact cools, the doctrine will not apply even though the initial provocation was adequate.
