Section 135/3: Supporter in a terrorism offence
Statutory text (Thai original)
ผู้ใดเป็นผู้สนับสนุนในการกระทำความผิดตามมาตรา ๑๓๕/๑ หรือมาตรา ๑๓๕/๒ ต้องระวางโทษเช่นเดียวกับตัวการในความผิดนั้น ๆ
English translation
Whoever is a supporter in the commission of an offence under Section 135/1 or Section 135/2 shall be liable to the same punishment as a principal in that offence.

Firm annotation
Like Section 129 in the security Chapter, this displaces the two-thirds reduction that Section 86 would otherwise give a supporter. A supporter of an offence under Section 135/1 or Section 135/2 is punished as a principal.
Why this matters in practice
ผลในทางปฏิบัติคือ ในกลุ่มความผิดฐานก่อการร้าย การเป็นผู้สนับสนุนไม่ได้รับการลดโทษสองในสามตามมาตรา 86 แต่ต้องรับโทษเช่นเดียวกับตัวการ ข้อต่อสู้จึงไม่ได้อยู่ที่ระดับของการมีส่วนร่วม แต่อยู่ที่ว่าผู้ถูกกล่าวหาเป็นผู้สนับสนุนในความผิดตามมาตรา 135/1 หรือมาตรา 135/2 จริงหรือไม่ และความผิดหลักนั้นเป็นความผิดตามมาตราใด เพราะโทษของผู้สนับสนุนเท่ากับโทษของมาตรานั้นทั้งหมด

Supreme Court Judgment No. 3807/2563 (2020)
A single course of insurgent conduct may be convicted under Section 135/3 alongside Sections 135/1 and 135/2 read with Section 86, with the heaviest law applied under Section 90 where the acts form one offence.
The defendant was charged and convicted under Sections 135/1(1)(3), 135/2(2) read with Section 86, 135/3 and 209 together with firearms offences. The courts treated part of the conduct as a single act violating several laws and applied the heaviest provision, confirming that the terrorism-threat count under Section 135/3 forms part of this scheme.

Supreme Court Judgment No. 222/2556 (2013)
Being a member of a secret society and supporting terrorism are separate offences with different intent and purpose, not a single act violating several laws, and are charged as separate counts.
The defendant was charged under Sections 135/1, 135/2, 135/3 and 209. The appellate court convicted under Sections 135/1(1)(3), 135/2(2) read with Section 86, 135/3 and 209, and the courts held that being in a secret society and supporting terrorism were separate offences with different intent, charged on separate counts.
