Firm annotation
Section 290 sits between intentional murder and negligent homicide: it punishes an intentional injuring of another where the offender had no intent to kill but death resulted. Its elements are an intent to injure, an act of injuring, and a resulting death that flows from that act. The absence of intent to kill is what separates it from Sections 288 and 289, while the presence of a deliberate act of injury separates it from the negligence offence of Section 291. Because it is a result-aggravated offence, general-part rules can extend liability: a co-principal who joined an assault answers for the death, and a death caused by mistaken aim (aberratio ictus) is reached through Section 60. Assault causing death is often the lesser offence a court finds proven when a murder charge fails on the intent-to-kill element.
Why this matters in practice
For a defendant this section is often the more favourable outcome when the prosecution cannot prove intent to kill, since exposure drops to three to fifteen years rather than the murder range. The decisive contest is therefore over intent, judged from the weapon, the force used, and the part of the body targeted. Note that joining a group assault can make a person liable for the death as a co-principal even without striking the fatal blow, so participation is itself a serious risk; the firm's overview of criminal law in Thailand gives context.

Supreme Court Judgment No. 3978/2567 (2024)
Where offenders intended only to injure but the victim died, liability lies under Section 290 for assault causing death, not murder; a co-principal answers for the shared result, including a death caused by mistaken aim through Section 60.
Having joined from the outset in beating the first victim, the defendant was liable as a co-principal for assault causing death under Section 290 paragraph one; the death of the second victim by mistaken aim made him liable under Section 290 with Section 60, both being lesser offences included within the charged murder.

Supreme Court Judgment No. 234/2567 (2024)
The intent to injure a child causing death under Section 290 is separable from the intent to commit a sexual offence, so the two are distinct offences punished as separate counts.
The defendant was convicted of assault causing death under Section 290 as an act of domestic violence; the Supreme Court held this intent was separable from the intent behind the rape charge, making them separate counts.
