Computer Crime Act Section 14(1) — Limits on Use for Defamation
Complainant v Online Commenter / Page Administrator
Composite summary — not a single reported case. This entry distils a settled line of Thai Supreme Court (Dika / ฎีกา) authority for legal education. It is not a transcript of one reported judgment, and the heading is not a citable case number. Do not cite it as specific case law — consult a Thai-qualified lawyer for the authoritative Dika number and current application.
Facts
A complainant filed parallel criminal complaints — for ordinary defamation under Penal Code Sections 326 and 328 (defamation by publication), and for 'inputting false data' under Section 14(1) of the Computer Crime Act B.E. 2550 (2007) — against a person who posted critical statements online. Following the 2017 amendments, Section 14(1) was clarified to target genuinely false computer data, not ordinary defamatory statements made online.
Legal Issue
Whether Section 14(1) of the Computer Crime Act applies to online defamatory statements, given the 2017 amendment that excluded 'acts that constitute defamation under the Penal Code' from Section 14(1).
Holding
Following the 2017 amendments, the Supreme Court has confirmed that Section 14(1) does not cover ordinary online defamation, which must instead be prosecuted under Sections 326 and 328 of the Penal Code (with the 'by means of advertisement' aggravator under Section 328 applicable to public online posts). Section 14(1) is reserved for inputting demonstrably false data that may cause damage to the public, public safety, the national economy, or critical infrastructure.
Reasoning
The 2017 amendment was a direct response to over-charging under Section 14(1), which had been used to add criminal weight to ordinary online speech disputes. The court reads Section 14(1) narrowly to align with its legislative purpose: preventing genuine cyber-fraud and disinformation that damages the public interest, not chilling personal speech disputes.
Significance
Critical for journalists, social-media users, and online businesses. Reduces — though does not eliminate — the 'double-barrelled' prosecution risk that previously made Thailand notorious for online defamation cases.
Practical Takeaway
Online defamation should be prosecuted under Penal Code Section 328, not Section 14(1) CCA. Defendants facing combined charges should challenge Section 14(1) at preliminary examination on the 2017-amendment basis.
