Section 72: Provocation (heat of passion)
Statutory text (Thai original)
ผู้ใดบันดาลโทสะโดยถูกข่มเหงอย่างร้ายแรงด้วยเหตุอันไม่เป็นธรรม จึงกระทำความผิดต่อผู้ข่มเหงในขณะนั้น ศาลจะลงโทษผู้นั้นน้อยกว่าที่กฎหมายกำหนดไว้สำหรับความผิดนั้นเพียงใดก็ได้
English translation
Whoever, being provoked to anger by being seriously oppressed through an unjust act, thereupon commits an offence against the person who so oppressed him at that moment, the Court may inflict on him a punishment less than that provided by law for such offence to any extent.

Firm annotation
Section 72 is the provocation provision in Book 1, a mitigating rule rather than a defence. Its elements are serious oppression by an unjust act, anger arising from that oppression, and an offence committed against the oppressor at that moment, while the passion still runs. The requirement that the response be against the person who provoked it, and that it be immediate, distinguishes provocation from calculated retaliation; a cooling-off period ordinarily defeats the plea, though the case law accepts that a short interval does not break the continuity if the anger has not subsided. Because it only mitigates, the doer is convicted of the underlying offence (often homicide under Section 288) but the court may sentence below the statutory range. It frequently appears alongside self-defence pleas and is assessed on the facts of provocation and timing.
Why this matters in practice
Section 72 is one of the most commonly used mitigation pleas in violent-offence cases, especially homicide, because it can drop the sentence well below the statutory range while the conviction stands. Success depends on two facts: that the accused was seriously and unjustly provoked, and that the reaction was immediate, directed at the provoker while the anger was still hot. The continuity point is often decisive; a brief interval, such as going home and returning, does not always break provocation if the fury had not subsided, but a genuine cooling-off usually does. Because provocation is fact-sensitive and frequently paired with a self-defence argument, careful presentation of the trigger and timing with a Thai criminal lawyer can materially reduce exposure.
Supreme Court decisions interpreting this section

Supreme Court Judgment No. 1109/2567 (2024)
Provocation under Section 72 is not broken by a short interval if the anger continues without subsiding; a defendant who briefly left and returned while still enraged acted in the heat of passion.
After being kicked in the face, the defendant rode home about 600 metres away and returned. The Court held that the short trip did not break the continuity of his anger, which was still boiling, so the act was committed under provocation within Section 72.

Supreme Court Judgment No. 2952/2567 (2024)
A defendant who kills the person who provoked him while in the heat of passion is guilty of killing under provocation, for which Section 72 permits a punishment below the statutory level.
The trial court convicted the first defendant of killing another under provocation, applying Section 288 with Section 72, and mitigated the sentence on that basis. The case illustrates provocation reducing the penalty for an intentional killing of the provoker.

Frequently asked questions
What is provocation under Section 72?
It is a mitigation for a person who, seriously and unjustly provoked to anger, commits an offence against the provoker while still in that heat of passion. The court may then impose a punishment below the statutory level to any extent.
Does provocation excuse the crime?
No. Section 72 only reduces the punishment; it does not remove guilt. The person is still convicted of the underlying offence but may receive a sentence below the statutory range.
Does a short delay defeat a provocation claim?
Not necessarily. The courts accept that a brief interval, such as briefly leaving and returning, may not break provocation if the anger had not subsided, but a genuine cooling-off period usually does defeat the plea.
