Supreme Court Judgments · Judgment No. 5764/2562Falsity is only one element of Section 14 (1). Supreme Court Judgment No. 5764/2562 confirms that the prosecution must also prove the specific intent to act dishonestly or deceitfully; otherwise, even false news does not satisfy all the elements of the offense.

No. The current Section 14 (1) does not punish everyone who enters incorrect data or false news into a computer system. The prosecution must also prove that the offender had the specific intent to act “dishonestly or deceitfully” and that the other elements of the provision are met.
Supreme Court Judgment No. 5764/2562 therefore matters to the media, website administrators, Facebook users, and litigants alike, because it shows that the word “false” is the starting point of the analysis, not a ready-made verdict.1
The facts conclusively found by the lower courts were that the defendant had posted false news on a website the defendant administered, at a time when the former Section 14 was still in force. The court of first instance convicted the defendant and imposed one year’s imprisonment and a fine of 20,000 baht, with the prison term suspended for one year. The Court of Appeal affirmed.1
While the case was pending, the 2017 (B.E. 2560) amendment came into force and added an element of specific intent. The defendant appealed to the Supreme Court on a question of law: whether the new law was more favorable to the defendant to the extent of relieving the defendant from being an offender. The Supreme Court accepted the appeal on this issue only and was bound by the facts as determined by the Court of Appeal.
The point to read carefully is that the Supreme Court did not re-decide whether the news was true or false; that factual issue had already been settled. The question was whether, even though the news was false, the act met the elements of the new law.
As amended in 2017 (B.E. 2560), Section 14 (1) provides, in summary, that there must be an act, done dishonestly or deceitfully, of bringing distorted, forged, or false computer data into a computer system in a manner likely to cause damage to the public, and that the act must not be an offense of defamation.2
There are therefore at least four hurdles:
If any one of these is missing, Section 14 (1) cannot be applied, even if the others have been proven.
The Criminal Code defines “dishonestly” as seeking, for oneself or another person, a benefit to which one is not lawfully entitled.3 As for “deceitfully,” one must look at the circumstances to see whether the offender purposefully used distorted, forged, or false data as a tool to mislead the recipients.
These two words mean that one must always go beyond “the news was wrong” and ask further questions, such as:
Specific intent can be proven from the surrounding circumstances; a confession is not required. A court should not, however, infer specific intent merely because the data ultimately proved to be untrue.
The Supreme Court held that the new law adds an element, namely the specific intent to act dishonestly or deceitfully. The facts settled by the Court of Appeal showed only that the defendant had posted false news on a website the defendant administered; no such specific intent was shown. The act was therefore not an offense under the new Section 14 (1).1
Because the later law was more favorable to the defendant, Section 2, paragraph two, of the Criminal Code required the new law to be applied. The Supreme Court reversed the judgment and dismissed the case.
The principle of lex mitior, under which a later law more favorable to the offender applies, prevents a person from being punished under an old law that still penalizes more broadly than the new law intends. In this case, the new law did not merely reduce the penalty; it added an element of the offense. If the facts do not support the added element, the act is no longer an offense.3
This principle differs from using a new law to create an offense retroactively: criminal law prohibits applying a law that is unfavorable to the offender retroactively, but allows a later law that is favorable to the offender to be applied.
| Type | Illustrative example | Issues to examine |
|---|---|---|
| Incorrect data published in good faith | Reporting an inaccurate figure because an outdated document was used | Knowledge, sources, verification steps, and correction |
| False news damaging a person’s reputation | Publicly accusing a person of cheating | Sections 326/328, the exemptions, and proof of truth; Section 14 (1) excludes defamation |
| False data used to obtain a benefit by deception | Creating a fake shop or investment scheme to induce money transfers | Dishonest or deceitful intent, damage, the injured persons, and the offense of fraud |
| False news causing public panic | Reporting a serious danger that does not exist | Section 14 (2) and the impact on the public |
This table shows that the everyday term “fake news” may lead to different legal bases, and that some cases may not be a criminal offense at all.
The three judgments can be read together as successive checkpoints under Section 14 (1).
| Judgment | Checkpoint at issue | Legal effect |
|---|---|---|
| 2778/2561 | The act is defamation | The same act is excluded from Section 14 (1)4 |
| 5764/2562 | No specific intent is shown | Falsity alone does not satisfy Section 14 (1) |
| 2211/2566 | The words “likely to cause damage to the public” | 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 one5 |
