Supreme Court Judgments · Judgment No. 2778/2561Supreme Court Judgment No. 2778/2561 does not hold that online posts are lawful. It confirms that if the same act is defamation, the current law carves it out of Section 14 (1), so the charge must match the interest that was actually harmed.

If the same set of facts amounts to defamation under the Criminal Code, the act is not an offense under the current Section 14 (1) of the Computer-related Crime Act merely because it was published on a website or on Facebook. The person may still be liable for defamation by publication under Section 328, or for another offense with different elements.
This is the core of Supreme Court Judgment No. 2778/2561, which corrects the belief that “if a false statement is on a computer, a Computer-related Crime Act charge must always be added.” In fact, the 2017 (B.E. 2560) amendment draws the line expressly: Section 14 (1) applies only to conduct which is not an offense of defamation1
The case began with a speech at a political group’s rally on 22 February 2011 (B.E. 2554), in which words were spoken that the court found to defame the plaintiff. Someone later transcribed the speech and published it on the website manager.co.th2
On appeal to the Supreme Court, the issue for the second defendant was the liability of the person holding the right to manage the website. The defendant argued that the original owner company had become bankrupt, so the right to manage the website had ended. The court held that the licensing agreement did not lapse merely because the licensor became bankrupt, and that the circumstances showed the second defendant had absolute authority to manage the website, including control over the content published.
The court therefore held that the second defendant was guilty of defamation by publication under Section 328 and imposed a fine of 60,000 baht. The next question was whether the same publication was also an offense under Section 14 (1) and (5) of the Computer-related Crime Act.2
At the time of the events, the former Section 14 (1) covered bringing forged or false computer data into a computer system in a manner likely to cause damage “to another person or the public.” Such broad wording was used in many reputation disputes.3
The Computer-related Crime Act (No. 2) B.E. 2560 (2017) then amended Section 14 (1) by adding key elements:
The new law came into force while the case was before the Supreme Court. Section 2, paragraph two, of the Criminal Code provides that if, under a law enacted afterwards, such an act is no longer an offense, the person who committed it is relieved from being an offender. The Supreme Court could therefore raise this issue on its own motion even though the defendant had not appealed on it directly, because it is a question of law concerning public order.2
Once the second defendant’s act was found to be defamation by publication under Section 328, it lacked the element the new law requires, namely that the act must not be an offense of defamation. The same act was therefore not an offense under Section 14 (1).
And since the source data was not data under Section 14 (1), the offense of publishing or forwarding it under Section 14 (5), which depends on that source data, did not arise either. The Supreme Court therefore modified the judgment so that the second defendant was liable under Section 328 alone.2
A common mistake is to start from the fact that “it was posted on a computer” and conclude that it must be a computer crime. Criminal law, however, classifies offenses by the interest the law protects and by their specific elements, not merely by the device used.
Facebook is therefore the “channel”; the offense must be found in “the content, the intent, the audience, and the interest the law protects.”
| Issue | Former Section 14 (1) | Current Section 14 (1) |
|---|---|---|
| Specific intent | No reference to acting dishonestly or deceitfully | Must be done dishonestly or deceitfully |
| Who suffers the damage | Another person or the public | Paragraph one refers to the public; paragraph two deals separately with damage to a particular person |
| Relationship with defamation | No express carve-out | States that the act must not be an offense of defamation |
| Outcome in this judgment | The act might have fallen within the former test | Under the later law, the act is not an offense under Section 14 (1) and (5) (Criminal Code, Section 2, paragraph two) |
This comparison explains why television commentary or some older articles saying “a false post violates the Computer-related Crime Act” may not reflect the provisions in force today.
| Judgment | Key question | Principle |
|---|---|---|
| 2778/2561 | Is the act already defamation? | If so, the same act is not an offense under Section 14 (1) |
| 5764/2562 | Was there the specific intent to act dishonestly or deceitfully? | False data alone is not enough5 |
| 2211/2566 | Did the damage reach “the public” under paragraph one? | The law sets no minimum number of viewers. Where the data is directed at the public in a system that members of the general public can access, a single actual viewer still satisfies paragraph one6 |

Suppose someone publicly posts that a shop owner “cheats customers,” while the person accused insists that it is untrue. The correct analysis is not to cite Section 328 and Section 14 (1) together straight away, but to ask, in order:
If there is only an imputation damaging reputation through Facebook, the principal offense is defamation, not Section 14 (1) for the same act. If there is a separate set of acts, the elements of each offense must be analyzed separately rather than lumped together.
