Section 6 — Participants acting from abroad
English translation
For any offence committed within the Kingdom, a co-principal, an instigator, or a supporter in the commission of that offence shall, even if the act was done outside the Kingdom, be punished as if the act had been committed within the Kingdom.

Firm annotation
Section 6 closes a jurisdictional gap left by the territoriality rule in Section 4. Where the principal offence occurs in the Kingdom, the participation forms defined in the General Part, the co-principal (Section 83), the instigator (Section 84), and the supporter (Section 86), attract Thai jurisdiction even if the participant acted entirely from abroad. The provision attaches liability to the location of the underlying offence rather than the location of the participant. It complements Section 5, which deems partly extraterritorial offences to be committed in the Kingdom, and together they ensure that persons abroad cannot escape Thai criminal law by contributing remotely to an offence that is committed in Thailand.
Why this matters in practice
Section 6 matters most for organized and cross-border offending, where an instigator or financier abroad directs or supports an offence carried out in Thailand. Such a person is exposed to Thai prosecution as a participant, and the exposure follows the participation rules: a co-principal generally faces the same penalty as the principal, while a supporter typically faces a reduced penalty. Being physically outside Thailand is not a defence where the principal offence was committed in the Kingdom. Anyone accused of supporting or instigating from abroad should focus on whether the underlying offence was committed in Thailand and on the exact form of participation alleged.
Frequently asked questions
Can someone abroad be prosecuted for helping a crime committed in Thailand?
Yes. Under Section 6, a co-principal, instigator, or supporter of an offence committed in the Kingdom is punishable as if acting within the Kingdom, even when acting from abroad.
Does Section 6 require the main offence to be in Thailand?
Yes. Section 6 applies only where the underlying offence was committed within the Kingdom; it then reaches participants who acted from outside Thailand.
