Thy Thorn had been held for 745 days when the Phnom Penh court of first instance sentenced him to seven years. Mean Chanthon and a woman whose name is usually written Kunthea got seven years each as well. LICADHO, a Cambodian rights group that had staff in the room, reported the sentences on 2 September 2026. So did Khmer Times, which named the judge as Nhim Pisal. Both put the same seven-year figure on all three.
The charge was plotting. Article 453 of the Criminal Code does not reach a plan to hold a protest. It asks for two things at once. There must be a resolution agreed between two or more people to commit an attack. There must also be material actions that put that resolution into effect. Agreeing is not enough on its own, and acting is not enough without the agreement.
Article 451 fixes what an attack is. It is one or more acts of violence liable to endanger the country’s institutions or its territory. So the offence turns on a violent act, agreed in advance by at least two people, and then carried some way into the world.
Two English translations of the code label the two offences differently. One calls them plotting and attack. The other calls them conspiracy and criminal attempt. Both require acts of violence, and both set the same five to ten years. Cambodia’s own filing abroad uses plotting and attack.
Two published accounts describe what the three are said to have done, and both come from the court. Khmer Times reported the hearing of 27 May 2026. That report says Thorn was arrested while allegedly persuading members of the Khmer Student Intellectual League Association to join a protest. It reports that prosecutors alleged Facebook posts the court called distorted. It attributes to court documents the claim that the three encouraged young people, garment workers and members of the armed forces to join a protest to overthrow the government.
The same paper reported the verdict three months later, this time from court records. That account describes using Facebook to call for public protests over the development area that Cambodia, Laos and Vietnam run together along their shared borders. Cambodia set that scheme up 25 years ago and withdrew from it in September 2024, a month after these arrests. The verdict account is shorter than the trial one and describes less. It does not contradict it.
The article asks for violence, agreed in advance and then carried into acts. What the two accounts put in front of the public is persuasion, posting and turnout. Both accounts came from the court itself, and the conduct in both is speech and organising.
Recruiting is not posting, and the trial account is the heavier of the two. Persuading members of the armed forces to join is an account of assembling something rather than of writing something. On its own it is the strongest thing in the public record against reading this as a case about Facebook. The armed forces claim is the part the report attributes to court papers. The account of Thorn being arrested mid-recruitment is the paper’s own.
That report also got the charge wrong at the top. Khmer Times led its verdict report with the phrase plotting protests, which is not the offence Article 453 creates. The body of the same report sets the law out correctly two sentences later. What the public knows about the conduct a Cambodian court described runs through a relay that mislabelled the charge in its own first sentence.
A guide to Cambodian law published by the University of Melbourne records that Cambodian courts do not publish their judgments. The exceptions it lists are the labour Arbitration Council and the Khmer Rouge tribunal. Neither is a criminal court of first instance, which is where criminal trials in the capital start. Sentences are public the moment a judge reads them out. Reasons stay in the file. No published ruling sits behind those two newspaper reports, and no list of the acts a judge found.
On 25 August 2025, Cambodia’s permanent mission in Geneva answered a group of UN special rapporteurs. Those are independent experts who work for the UN, write to governments about named cases, and have both their letters and the answers published. Dara In, the ambassador who heads the mission, signed the reply, which carries the mission’s file number 2025/08/666. It went out a year before the verdict.
The reply states that taking part in the plan constitutes plotting under Article 453. Separately, it sets out the other half of the charge, the violent attack described in Articles 451 and 452. Cambodia therefore set out both limbs in writing, abroad, over a signature, a year before the court delivered these sentences.
The part of that reply dealing with Thy Thorn names the order for his arrest and the order for his detention. An arrest order and a detention order record that the state acted. They are not an account of conduct. The reply then refers to the relevant evidence in the case, without setting any of it out. It names no weapon. It names no target. It names no message and no material act.
That is one document, read in full, on one date. It answers human rights experts, not a trial court. It predates the verdict by more than a year. What such a reply leaves out is not what a prosecutor holds. Nothing in it fixes the state of the file.
Elsewhere in the same paper, Cambodia says nine ringleaders were sent to court on proof that included weapons and messages about overthrowing the state. Nothing in the public record places these three inside or outside that nine.
Mean Chanthon and Kunthea are not in the reply at all. The written account Cambodia gave of this case abroad covers one of the three people who later received seven years each. Sources spell Kunthea’s name differently, and none carries a Khmer original, so the spelling used here follows the sources rather than any record of her own.
The same reply describes how long Cambodia may hold a felony suspect before trial. Six months, extendable twice by six months each, which is eighteen months in all. The reply also says an investigating judge extended Thorn’s detention after hearing his lawyer, reasoning that people involved had not been identified and the investigation was complex. Thy Thorn was arrested on 18 August 2024, on the date both LICADHO and Khmer Times carry, and sentenced on 2 September 2026. The 745 days between those dates is this desk’s own count. The eighteen months the reply describes govern the period before a case reaches trial. Nothing public divides the 745 days between that period and the trial itself.
Seven years is the midpoint of the band Article 453 sets, which runs from five years to ten. That leaves two years below them and three above. Incitement, the charge most of the others rounded up in 2024 were convicted of, runs from six months to two years in the same code, which does not make it a felony at all.
Son Chum Choun, who defended them, says the case concerns opinions posted on Facebook and that no facts constituting plotting exist. He said so to CamboJA, an association of Cambodian journalists that runs its own newsroom, and to Khmer Times. He is the lawyer for the side that lost, and that is a party’s claim rather than a finding. The court did not accept it. Across the four outlets that reported the verdict, his account and the court’s are the only two from inside the room.
Thai immigration officers had arrested Mean Chanthon and Kunthea on 24 November 2024 and sent them back to Cambodia the next day. Human Rights Watch said at the time that six adults went back. Five of them held refugee status from the UN refugee agency and one was still awaiting a ruling, it said, and it did not say which was which.
A United Nations report published in September 2025 counts it differently. It says five activists were returned with two family members. The activists had been recognised as refugees, it says, and it was a family member who was still waiting. Two of the three now serving seven years were carried back across a border to answer this charge.
The plotting case file dates from 15 August 2024, Human Rights Watch recorded. The protest and the arrest warrants came three days after that. Am Sam Ath of LICADHO says the Interior Ministry carries the student group on its register. A UN panel on arbitrary arrest recorded in November 2025 that the group was shut down after its president was arrested in 2024.
The defence says it will appeal. Thy Thorn’s 745 days in custody now run on into a seven-year term, argued against reasons no court has published.
Another man is already inside the same article. Rath Sothy, a deputy commune chief in Battambang and a Candlelight Party district chief, was arrested on a farm on 12 January 2026 and charged under Article 453. LICADHO reported then that it was not clear what he was said to have done. Six months later, when the appeal court refused to free him, LICADHO reported that the charge related to Facebook posts he had shared and commented on. He has been held since January. The court holding his case does not publish its reasons either.
