A common-law doctrine that reduces an intentional killing from murder to voluntary manslaughter when the defendant acts in the heat of passion upon adequate provocation and before a reasonable cooling-off period has elapsed. Adequate provocation must be of a type that would arouse sudden and intense passion in an ordinary person, the defendant must have been actually provoked, and the defendant must not have cooled off before the killing. Certain situations such as a serious battery on the defendant or a close relative or discovering a spouse in the act of adultery qualify as adequate provocation while mere words, trivial battery, and old wrongs do not.

Pavel Petrov returned home early from work and found his wife in bed with another man. Overcome by sudden rage, Pavel immediately grabbed a nearby object and struck the man, killing him. The facts establish adequate provocation under the doctrine because catching a spouse in the act of adultery qualifies as a recognized category that can reduce what would otherwise be murder to voluntary manslaughter.
Pilar Pena provoked Preston Pratt during an argument by insulting him repeatedly. Preston responded by punching Pilar in the face, causing a broken nose and medical expenses. In Pilar's subsequent tort suit, the provocation does not reduce her compensatory damages for the injury but is considered in determining whether and how much punitive damages she may recover.
Parker Phillips became enraged when Patrick Phan called him a liar during a business meeting. Parker retrieved a knife from his desk and fatally stabbed Patrick.

Priscilla Parks learned that her neighbor had just seriously battered her brother. In immediate rage she confronted the neighbor and intentionally killed him with a knife.

Patrick Phan discovered his wife in an adulterous act in the morning. He left the house, spent the afternoon reflecting, and returned that evening to kill her lover. The time that elapsed allowed a reasonable person's passion to cool, so the doctrine does not reduce the killing to voluntary manslaughter.
Prism Analytics employee Pavel Petrov learned of a serious battery on his brother at work. After learning the news he calmed himself, completed his shift, and then returned the next day to kill the assailant. Because Pavel had in fact cooled off before the killing, the provocation doctrine does not apply to reduce the offense.
The provocation must be of a kind that would cause an ordinary person to experience sudden and intense passion. The defendant must have actually experienced that passion. There must not have been sufficient time for a reasonable person's passion to cool. The defendant must in fact not have cooled off before the killing.

Adequate provocation includes 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 when 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.
