Article 52: Reduction of the death penalty

Statutory text (Thai original)

ในการลดโทษประหารชีวิต ไม่ว่าจะเป็นการลดมาตราส่วนโทษหรือลดโทษที่จะลง ให้ลดดังต่อไปนี้ (๑) ถ้าจะลดหนึ่งในสามให้ลดเป็นโทษจำคุกตลอดชีวิต (๒) ถ้าจะลดกึ่งหนึ่ง ให้ลดเป็นโทษจำคุกตลอดชีวิต หรือโทษจำคุกตั้งแต่ยี่สิบห้าปีถึงห้าสิบปี

English translation

In reducing the death penalty, whether it is a reduction of the scale of punishment or a reduction of the punishment to be imposed, the reduction shall be as follows:
(1) if the reduction is by one-third, it shall be reduced to imprisonment for life;
(2) if the reduction is by one-half, it shall be reduced to imprisonment for life or imprisonment from twenty-five years to fifty years.

Firm annotation

Section 52 translates a percentage reduction of the death penalty into a defined term, since death cannot be expressed as a fraction. It covers both reduction of the scale of punishment and reduction of the punishment to be imposed. A one-third reduction yields imprisonment for life; a one-half reduction yields either imprisonment for life or a term of twenty-five to fifty years, giving the court a range at the halfway level. It works with Section 53 (reduction of life imprisonment) and Section 54 (order of calculating increases and reductions), and is commonly applied together with the general mitigation reduction in Section 78.

Why this matters in practice

For a capital defendant, a mitigating factor such as a useful confession can be the difference between death and a term of years, because Section 52 converts the reduction into life imprisonment or, at the half level, a term as low as twenty-five years. The choice within the twenty-five to fifty year range on a one-half reduction is the court's, so mitigation submissions still matter after death is off the table. In the most serious cases, early and careful defense preparation is essential; consider speaking with a Thai lawyer.

Décisions de la Cour suprême interprétant cette section

  1. Arrêt de la Cour suprême n° 2585/2568 (2025)

    The trial court sentenced the first defendant to death for joint murder and, on his plea of guilty, reduced that punishment by one half under Section 78 read with Section 52(2), which turned it into imprisonment for life. Because the punishment as reduced was imprisonment for life, section 245 paragraph two of the Criminal Procedure Code made the judgment not final unless the Court of Appeal affirmed it, so even though the defendant appealed only against the severity of the sentence, the Court of Appeal had to consider and decide first whether he had committed the offence at all.

    The court of first instance sentenced the first defendant to imprisonment for life for joint murder, and he appealed only asking for a lighter sentence. The Court of Appeal Region 7 considered only that ground. The Supreme Court held that unlawful: under section 245 paragraph two of the Criminal Procedure Code the Court of Appeal had to decide whether he committed the offence at all before the judgment could become final. Taking the point of its own motion as one of public order, it set aside the judgment of the Court of Appeal Region 7 and sent the case back for a fresh judgment. It made no ruling on any reduction of punishment under Section 52.

  2. Arrêt de la Cour suprême n° 2813/2568 (2025)

    Premeditated murder under Section 289(4) carries the death penalty only, and an attempt is punished at two-thirds of it; reducing the death penalty by one-third under Section 52(1) leaves imprisonment for life.

    The court explained that premeditated murder under Section 289(4) carries the death penalty only and an attempt is punished at two-thirds of it. Reducing the death penalty by one-third under Section 52(1) leaves imprisonment for life, which the lower courts then halved under Section 78 to twenty-five years.

  3. Arrêt de la Cour suprême n° 6190/2567 (2024)

    Section 52 governs the reduction of a death penalty. Where the court finds the offence is murder under Section 288 and imposes imprisonment for life, a reduction by one half is made under Section 53, not Section 52, and leaves twenty-five years.

    The lower courts had convicted of premeditated murder committed with torture or cruelty and imposed the death penalty, reduced by one half for the confession. The Supreme Court held there was no evidence of premeditation, the stabbing having happened suddenly, and dealt with the torture and cruelty limb of its own motion as a question of public order. It varied the judgment to a conviction for murder under Section 288, imposed imprisonment for life, and reduced that by one half under Section 78 read with Section 53, leaving twenty-five years. Section 52 (2) was not applied.

Foire aux questions

Comment la peine de mort est-elle réduite en Thaïlande ?

En vertu de l'article 52, une réduction d'un tiers de la peine de mort devient une peine d'emprisonnement à vie, et une réduction de moitié devient une peine d'emprisonnement à vie ou une peine de vingt-cinq à cinquante ans.

Un plaidoyer de culpabilité est-il utile dans une affaire capitale ?

C'est possible. Une réduction de peine, telle qu'une réduction pour aveu, appliquée en vertu de l'article 78 combiné à l'article 52, transforme la peine de mort en emprisonnement à vie ou en une peine d'emprisonnement à durée déterminée.
