Facebook Marketplace Fraud in Thailand: Supreme Court Case 736/2569

Last updated on 28 September 2026

A Facebook Marketplace listing for goods you do not have is not a private lie between two people. It is fraud on the public. Supreme Court Decision (Dika) No. 736/2569 matters on four points for anyone buying or selling online in Thailand. The seller, who confessed, was convicted under Section 343 of the Penal Code, not the milder Section 341, and the Supreme Court held the charge properly pleaded. The same post is also an offence under Section 14(1) of the Computer Crime Act, though as one act offending several provisions it drew a single penalty under Penal Code Section 90. Restitution well above the victim’s actual loss, with a confession and nearly ten clean years, is what earned a suspended sentence. And a juvenile record can be used against the same person once they are tried as an adult.

The four holdings at a glance

Issue	What Dika 736/2569 holds	Why it matters
Which fraud section applies to an online listing	Penal Code Section 343 (fraud on the public), not Section 341	Higher penalty, and Section 343 is not compoundable
Computer Crime Act exposure	The listing is also false computer data under Section 14(1)	Two convictions from one post
Suspended sentence	Paying 20,000 baht on an 8,500 baht loss, with a confession and nearly ten clean years, justified suspension	Restitution is the factor a defendant controls
Juvenile record	Section 84 of the Juvenile and Family Court Act protects the child only inside the juvenile forum	An ordinary criminal court may weigh the record when deciding whether to suspend

A public listing is public fraud: Penal Code Section 343

Most fraud prosecutions in Thailand start with Section 341 of the Penal Code. That is ordinary fraud: dishonestly deceiving another person to obtain property. It carries up to three years in prison, a fine of up to 60,000 baht, or both.

Section 343 is the aggravated form. It applies where the deception is held out to the general public. The penalty rises to five years, a fine of up to 100,000 baht, or both.

Here is the part people miss. A Marketplace listing is addressed to everyone who scrolls past it. It does not become a private transaction just because one buyer happened to answer. In Dika 736/2569 only one buyer was shown to have paid, and the conviction under Section 343 stood; the Supreme Court also noted, when sentencing, that a public post could have deceived many more.

That distinction has a sharp practical edge. Under Section 348, most fraud offences in this chapter are compoundable, which means the case can be settled and withdrawn. Section 343 is not on that list. So the seller who assumes a refund will make the file disappear is working from the wrong section.

Section 341 compared with Section 343

	Section 341	Section 343
Who is deceived	An identified person	The public at large
Maximum prison term	3 years	5 years
Maximum fine	60,000 baht	100,000 baht
Compoundable under Section 348	Yes	No
Typical fact pattern after 736/2569	One-to-one deal, private message, known counterparty	Marketplace post, public group, open advertisement

The same post is a Computer Crime Act offence: Section 14(1)

Section 14(1) of the Computer Crime Act punishes dishonestly entering false computer data into a computer system in a way likely to cause damage to the public, other than defamation. It carries up to five years, a fine of up to 100,000 baht, or both.

The 2017 amendment deliberately narrowed Section 14(1). It was pulled away from defamation and pointed at exactly this: online fraud, phishing and fake commercial offers. A listing for stock that does not exist sits in the centre of that target.

So one Facebook post produces two offences. The deception of the buyer is the Penal Code count. Publishing the false data is the Computer Crime Act count. We explain how Thai prosecutors combine online charges in our guide to charge stacking under the Computer Crime Act.

In our experience, foreign defendants underestimate this badly. They picture a consumer dispute over a phone that never shipped. What they are actually facing is a non-compoundable public fraud charge stacked with a computer offence.

Restitution above the loss is what earns a suspended sentence

Thai courts can suspend a prison term under Section 56 of the Penal Code. Whether they do is discretionary, and remorse is the hinge.

Dika 736/2569 puts a number on remorse. The seller paid 20,000 baht on an 8,500 baht loss, more than double, and the Supreme Court called that a sufficiently high amount to relieve the harm. It weighed that together with his confession, the fact that only one victim was shown, and nearly ten years without offending since his juvenile cases, and suspended the six-month term for two years with a year of probation.

In our experience, three practical rules follow:

• Pay early. Restitution offered after conviction carries far less weight than restitution paid before the prosecutor files.
• Pay in full, then above. Instalments and part-payments signal negotiation, not remorse.
• Document it. A bank transfer slip, a signed acknowledgement from the victim, and a withdrawal of the complaint where the offence permits one.

Compare this with Dika 914/2569, where the court refused to suspend a four-month term for title deed fraud. The defendant there had not made the victim whole. The contrast between the two decisions is the clearest guidance Thai courts have given in years on what actually moves a sentencing judge.

A juvenile record follows you: Section 84 of the Juvenile and Family Court Act

This is the holding that surprises people, including lawyers.

Section 84 of the Juvenile and Family Court Act shields a child from having earlier proceedings held against them. The defendant argued that the shield travels with the person. Dika 736/2569 says it does not.

The protection is forum-specific. It operates inside the Juvenile and Family Court. Once the same individual is an adult standing trial in an ordinary criminal court, the court may take the juvenile record into account as part of the defendant’s history when deciding whether to suspend a sentence under Section 56.

The consequence is concrete. That record can be put before the court on sentencing. It can be the reason a suspension under Section 56 is refused. A person who assumed their file was sealed at eighteen may find it decides whether they walk out of the courtroom.

If you are advising a young client in Thailand, this changes the calculus at the juvenile stage. What is disposed of quickly in the juvenile forum is not disposed of permanently. Our guide to criminal trial procedures in Thailand covers how sentencing courts treat prior records.

What this means for you

If you sell online: never list what you do not hold. A pre-order you cannot fill is not a business risk, it is Section 343 exposure. Take the listing down the moment stock is gone. Refund immediately and completely if you cannot deliver.

If you were scammed: screenshot the listing, the chat and the transfer slip before anything is deleted. File a police report. Because Section 343 is not compoundable, the prosecution can proceed even where you have been repaid, and your evidence still matters. See our guide to fraud and scam laws in Thailand for the reporting route.

If you are an expat: two traps. First, a casual resale post in a Bangkok expat Facebook group is a public advertisement in the eyes of Thai law. Second, a criminal fraud conviction has immigration consequences that outlast the sentence. Get advice before you respond to a summons, not after. Start with your rights if you are arrested in Thailand.

Last reviewed: 28 September 2026. Supreme Court decisions 736/2569 and 914/2569 were read in Thai to their dispositions, with Penal Code sections 56, 78, 90, 341, 343 and 348 and section 14 of the Computer Crime Act as amended in 2017. The practical advice on timing and documenting restitution is experience, not a holding.
