Question 1

What are the elements of criminal defamation under Section 326?

Accepted Answer

The offence requires imputing something to another person to a third party — speaking or writing in a way that identifies or clearly points to the victim — where the statement is likely to damage reputation, expose the person to contempt, or hatred, plus intent, meaning the speaker knew the statement would reach someone other than the victim. The statement need not be false; even a partly true statement can qualify if it damages reputation, unless a statutory defence applies. A public online post inherently reaches third parties, so this element is usually satisfied more easily than in a private conversation.

Question 2

How does Section 328 aggravated publication differ from Section 326?

Accepted Answer

Section 328 is the aggravated form of Section 326, applying when the defamation is published through documents, drawings, paintings, film, images or lettering made visible by any means, recordings, or other means of dissemination that make it widespread. A social media post visible to the public falls within this publication concept, carrying heavier penalties in both imprisonment and fine than ordinary spoken defamation. Courts often weigh the number of viewers, share counts, and whether privacy settings were public or restricted. Victims typically invoke this section when a post reached a wide audience.

Question 3

What legal basis supports a civil claim for defamation damages?

Accepted Answer

Under the general tort rule in the Civil and Commercial Code, a person who unlawfully harms another, whether deliberately or through carelessness, owes compensation for that harm; a further provision deals specifically with asserting or circulating a statement contrary to the truth that is injurious to another's reputation or credit. Both are entirely separate from the criminal offence: a civil claim can proceed without any criminal case, and even a criminal acquittal does not always bar it because the standards of proof differ. Recoverable damages cover both reputational harm and any provable pecuniary loss flowing from the statement.

Question 4

How does the Computer Crime Act interact with online defamation?

Accepted Answer

The Computer Crime Act was previously invoked alongside Sections 326 or 328 for online defamation, particularly Section 14's ban on inputting false data likely to cause damage. Following amendments and a line of Supreme Court rulings, courts have held that where content already amounts to defamation under the Penal Code, Section 14 should not be stacked on top to avoid excessive duplicate liability, unless the content is purely fabricated data unrelated to imputing something to a specific person, or involves impersonating someone else. A complainant should check the facts carefully before choosing which offence to allege.

Question 5

How should a screenshot of a defamatory post be captured to serve as evidence?

Accepted Answer

Capture the full post text, the posting account's name, the date and time, the complete URL of the page or post, and the like or comment count at that moment. Record both still screenshots and a screen-recording video while scrolling to confirm nothing was edited, and repeat the capture at several intervals to show the post remained up over time. Where possible, have a third party witness and countersign a record of the event, or use an electronic notarisation service that timestamps the file. For trial, line up a digital forensic witness to authenticate the file if the other side disputes it.

Question 6

If the other side claims the screenshot was doctored, how is authenticity proven?

Accepted Answer

Keep the original file without re-saving or compressing it, along with its metadata showing creation time and the capturing device. If the platform has not yet removed the post, a lawyer can seek a court order compelling the platform to produce traffic data or its own database copy of the post, which is independent and stronger evidence than a self-captured image. Witnesses who saw the post at the same time can also testify to corroborate it. Where the dispute is serious, the file may need to go to a digital forensic expert to examine for signs of tampering.

Question 7

How does reporting to police differ from filing a private prosecution, and which to choose?

Accepted Answer

Defamation is a compoundable offence, so the victim can choose either to report it to the police for the investigating officer to prosecute, or have a lawyer file a private prosecution directly with the court as plaintiff. Reporting carries no litigation cost but requires waiting through an investigation that can take months, and the public prosecutor may decide not to indict if the evidence seems insufficient. A private prosecution gives more control over pace and direction, but requires a preliminary inquiry hearing before the court accepts the case, and the victim bears the full burden of proof through counsel at every stage. Where evidence is strong and speed matters, a private prosecution is often preferred.

Question 8

When does the three-month complaint period for defamation start running?

Accepted Answer

Defamation is a private offence, and the victim must lodge a complaint within three months of learning of the offence and identifying the offender — not from the date the post first went up. If the poster's identity is unknown at first because a fake account or alias was used, the clock starts only once the true identity is discovered. Once three months pass, the right to complain lapses, meaning police can no longer prosecute and the victim cannot bring a private case either. Consult a lawyer and act promptly upon discovering the post rather than negotiating with the poster until the deadline is missed.

Question 9

What channels exist to have a defamatory post taken down?

Accepted Answer

The first route is the platform's own content-reporting system, flagging the post as a privacy violation or false statement, though outcomes and timing are entirely at the platform's discretion. The second is a lawyer's cease-and-desist letter sent directly to the poster demanding removal by a set date, which often works faster once the poster recognises the legal risk. The third is a court petition under the Computer Crime Act seeking an order to suspend dissemination or remove the data from the system, which can proceed even without knowing the true poster, filed through officials appointed by the Ministry of Digital Economy and Society to obtain a court blocking order.

Question 10

What is the process for a court order blocking a website or post?

Accepted Answer

Officials under the Computer Crime Act gather evidence that the content falls within the law, such as offending public order or good morals, or unlawfully infringing another's rights, then petition the Criminal Court or the court with jurisdiction for an order to suspend dissemination or remove the data. Private victims usually need to go through a police report first so officials can file the petition on their behalf. The process can take weeks to months depending on court caseload, and any resulting order generally binds only domestic internet service providers or platforms; if the server sits abroad, a direct complaint to the platform is often needed in parallel.

Question 11

When does the good-faith fair-comment defence apply?

Accepted Answer

Section 329 protects statements or opinions made in good faith to protect a legitimate interest, in self-defence or defence of one's own legitimate interest, fair comment on persons or matters that the public is entitled to comment on, or a fair report of proceedings conducted openly in court or at a meeting. Common examples include reviewing an artist's, politician's, or business's public conduct. The comment must rest on facts that genuinely exist and must not cross into personal abuse or unrelated imputations. Courts weigh the overall intent and tone of the statement together in deciding whether the defence holds.

Question 12

How does the truth-for-the-public-interest defence work?

Accepted Answer

Section 330 allows a person accused of defamation to prove the statement was true, and if proven, no penalty applies, except where the imputation concerns purely private matters offering no public benefit even if true. This differs from the Section 329 defence in that the entire factual assertion must be proven true, not merely shown to be an honestly held opinion. The burden of proof rests on the accused, so documentary or witness evidence confirming the facts should be lined up in advance. If only part can be proven, the court may treat it as mitigation rather than a full acquittal.

Question 13

How much legal risk does a product or service review carry?

Accepted Answer

A review honestly describing one's own actual experience — a defective item, a delayed service, or a rude staff member — is generally protected as either a true fact or a good-faith fair comment under Section 329. Risk rises sharply once the wording exaggerates beyond the facts, makes unsupported accusations, or generalises from a single incident into a broad claim of dishonesty about the business. Attach supporting evidence such as receipts, product photos, or chat logs with the seller, and avoid vulgar language or wording that implies an unfounded criminal accusation. Businesses hit by a negative review often send a warning letter before actually suing, so respond promptly with facts and evidence upon receiving one.

Question 14

Does making accusations in a closed LINE or Facebook group count as defamation?

Accepted Answer

It still reaches a third party even in a closed or members-only group, as long as anyone other than the victim reads the message; group size is not the deciding factor, and even a group of two or three can satisfy the element. The key difference is that large or effectively public groups often get classified as aggravated publication under Section 328, carrying heavier penalties. Screenshots of group chat messages serve as evidence just like public posts. A group administrator who knowingly lets the message stay up may, in some cases, face consideration of joint liability as well.

Question 15

Does sharing or retweeting someone else's defamatory post also create liability?

Accepted Answer

Re-sharing without adding new commentary can still satisfy the elements of defamation if the share spreads the false or damaging statement to additional followers, especially where the sharer has a large following amounting to further publication under Section 328. Liability becomes clearer still if the sharer adds a caption reinforcing or vouching for the claim's credibility. Conversely, sharing with a caption questioning the claim or urging readers to verify facts first may fall short of the intent element. Anyone receiving a suspicious message should verify its source before hitting share, to avoid becoming a co-defendant.

Question 16

What special defamation exposure applies to online media outlets and journalists?

Accepted Answer

Media outlets receive protection under Section 329 when reporting fairly and giving a fair account of proceedings held openly in court or at a public meeting, but this protection does not extend to coverage that blends personal opinion with fact in a way that leads readers to believe guilt has already been confirmed before a final court judgment. Outlets should clearly flag matters as mere allegations or ongoing proceedings and give the other side space to respond within the same piece. A headline that overstates the actual story to drive clicks can also be sued separately from the article body, since it stands as its own statement seen by many readers who never read the full text.

Question 17

Does a public apology genuinely help end the case or secure a withdrawal?

Accepted Answer

Defamation is compoundable, so the victim may withdraw the complaint or the case at any stage before final judgment. A public apology combined with removing the post and agreed compensation is a common route to ending a case without waiting for a verdict, but an apology alone, without agreeing on compensation, may not be enough to persuade the victim to drop it. Any settlement should be put in writing specifying exactly what is exchanged for withdrawing the complaint or the case, to prevent renewed disputes later. Once the matter reaches court, withdrawal may in some situations still require the court's leave under the applicable procedure.

Question 18

How do courts calculate reputational damages for defamation?

Accepted Answer

There is no fixed formula for reputational damages since the harm is not directly monetary; courts exercise discretion based on the severity of the statement, the extent of dissemination such as viewer or share counts, the victim's prior standing and career position before the accusation, any provable consequences such as lost clients or termination of employment, and whether the offender acted maliciously or refused to remove the post after being notified. Where clear monetary business loss can be proven, such as a sales drop compared to the prior period, the court may award that separately from the direct reputational damages.

Question 19

What is a strategic lawsuit against public participation, and how do Sections 161/1 and 165/2 protect against it?

Accepted Answer

A SLAPP suit uses legal process, typically a defamation charge, to pressure a critic or whistle-blower into silence by imposing financial and time burdens heavy enough to deter further speech, even when the filer knows the case lacks real merit. Section 161/1 of the Criminal Procedure Code empowers the court to conduct a rigorous preliminary inquiry and dismiss a case where the plaintiff filed in bad faith or distorted facts to harass the accused. Section 165/2 lets the accused present evidence at that same preliminary inquiry stage to show the case lacks merit, rather than waiting for a full trial. Together these sections are key tools defence counsel use to end harassment suits early.

Question 20

How can someone recognise that the case filed against them is a SLAPP suit?

Accepted Answer

Common warning signs include a plaintiff who is an organisation or individual with clearly far greater legal resources than the accused, filing only after the accused published information or criticism on a public issue such as environmental harm or corruption, claiming damages wildly disproportionate to any provable actual loss, filing multiple simultaneous criminal and civil cases over the same issue, or filing in a court far from the accused's residence to raise the burden of travel. When these appear, counsel should be ready to raise them immediately at the preliminary inquiry under Sections 161/1 and 165/2, gathering evidence of the plaintiff's harassing intent such as a pattern of similar suits against other critics.

Question 21

What are the criminal penalty ranges under Sections 326 and 328?

Accepted Answer

Section 326 carries imprisonment of up to one year or a fine of up to twenty thousand baht, or both. Section 328, the aggravated publication form, raises this to imprisonment of up to two years and a fine of up to two hundred thousand baht. Actual sentencing depends on circumstances such as the severity of the statement, remorse and compensation paid before judgment, and any history of repeat offences. Many cases end in a fine or a suspended sentence where the accused has no prior record and agrees to compensate the victim. This criminal penalty is entirely separate from civil damages, which must be claimed in a separate action to actually recover the loss suffered.

Question 22

How can the true identity of an anonymous poster be traced?

Accepted Answer

The first step is filing a police report, which gives investigators authority to request traffic data from internet service providers and platforms based on the posting account's IP address, access that ordinary individuals cannot obtain directly. If the account is linked to a phone number or a bank account used for a transfer or paid advertisement, that gives investigators another lead. Where the platform is based abroad, international cooperation through the Office of the Attorney General may be needed, which typically takes longer than a domestic request. While the investigation is pending, the victim should preserve evidence of every related post in full, since posts may be deleted or the account closed before identification is completed.

Question 23

What risks arise when an employee posts criticism of an employer or coworker on social media?

Accepted Answer

Venting general frustration without naming an identifiable person or organisation carries low criminal risk, but naming a specific person or company alongside an unsupported accusation, such as baseless claims of corruption, can satisfy the elements of defamation and expose the poster to suit from either an individual or a juristic entity, which has the same right to sue for defamation as a natural person. An employer may also cite such a post as grounds for dismissal, treating it as serious misconduct if it meets the conditions in the work regulations. An employee wishing to raise workplace problems is better served using internal grievance channels or the labour protection authorities than a public post, reducing civil, criminal, and employment risk all at once.

Question 24

Can a company or juristic person sue for defamation in its own right?

Accepted Answer

Yes. A juristic person's commercial reputation and standing receive the same legal protection as an individual's. If someone alleges without evidence that a company defrauds customers or sells substandard goods, the company can prosecute criminally, with its authorised director filing the complaint on its behalf, and civilly claim damages to its commercial reputation that may directly affect sales. One caution: a large company suing an individual consumer or a former employee risks being perceived as a SLAPP suit, so the reasonableness of the damages sought and lighter alternatives, such as negotiation or a takedown request, should be weighed before committing to full litigation.

Question 25

Should settlement be negotiated before trial, and what are the trade-offs?

Accepted Answer

Settling saves the time and cost of litigation that can drag on for years and avoids the risk of an unfavourable judgment, particularly where each side's evidence carries roughly similar weight. However, if the accused genuinely believes they are innocent and holds solid evidence, agreeing to pay may be read as an implicit admission of fault that harms their standing long term. Before deciding, weigh with counsel the odds of winning, the further legal costs that continued litigation would incur, and the reputational impact on both sides, while always setting a compensation ceiling and confidentiality terms in the settlement in advance.

Question 26

Can a suit proceed if the poster is abroad or the platform is based outside Thailand?

Accepted Answer

Thai courts can take jurisdiction where the effect of the act occurs in Thailand, for instance where the victim resides in Thailand and suffers reputational harm there, even if the poster is abroad. The practical hurdle is cross-border service of process and enforcement, which requires international service through diplomatic channels or a mutual legal assistance treaty, making the case take far longer than usual. In practice, when actual enforcement proves unrealistic, many victims focus on getting the platform to remove the content or suspend the account through its reporting process rather than pursuing damages to a truly enforceable conclusion.

Question 27

From what point should evidence-gathering start to avoid losing legal rights?

Accepted Answer

Evidence should be captured the moment a post is discovered, without waiting for the matter to escalate or for a lawyer consultation, since the post's owner can delete it or close the account at any time. Beyond screenshots and screen recordings, note the date and time first seen in writing to measure against the three-month complaint deadline. If witnesses saw the post as well, have them record and countersign an account promptly. Waiting too long risks not only losing the evidence but also giving the other side an argument that the harm could not have been serious since so much time passed without any action.
