On 8 March, the criminal court ordered the detention pending trial of Panusaya Sitthijirawattanakul, Jatupat Boonbattararaksa and Panupong Jadnok, leading figures in the pro-democracy protests, on sedition, royal defamation and several other charges. Piyarat Chongtep, leader of the We Volunteer protest guard group also detained for criminal organization

The first 3 reported along with another 14 people as scheduled on 8 March morning to be charged over the 19-20 September 2020 protests at Thammasat University and Sanam Luang. In total, they were charged with sedition, organizing more than 10 people to cause disorder, unlawful procession, emergency decree, vandalism and destroying antiquity site. Only the 3 had additional charge on royal defamation. 14 were allowed bail.

There were actually 15 people summoned to the court in this set of lawsuit. Only 14 were able to made to the court as the another one, Chaiamorn ‘Ammy’ Kaewwiboonpan has already been detained in prison.

Piyarat was arrested along with another 47 We Volunteer (WeVo) members by a SWAT police team who used force and did not produce an arrest warrant on 6 March prior to the protest at the judicial court complex. All but Piyarat were allowed bail. The WeVo case process is still in the police stage.

Movement supporters expressed disappointment and anger after bail was again refused by gathering at the Victory Monument on the evening of 8 March to protest. They asked people to dress in black as a symbolic show of resistance before dispersing at around 21.00.

Amnesty International released a statement claming that the mass prosecutions, amount to 382 protest leaders and demonstrators in 207 cases since 2020, tantamount to systematic suppression of freedom.

“It is profoundly worrying that the Thai authorities are systematically prosecuting a large number of protest leaders and demonstrators. In certain cases, the suspects may face up to 15 years of imprisonment. This is a severe and disproportionate punishment. Given the normally protracted period of trial, the prosecution of dissenters or critics of the government is being weaponized to silence and retaliate against those who dare to challenge the state power.” said Piyanut Kotsan, Director of Amnesty International.

“Mass prosecutions and denial of bail demonstrate how the justice process is being used as a tool to brazenly attack the right to freedom of expression and peaceful assembly. People are entitled to legitimate rights to express themselves and participate in activities concerning social issues.

“The Thai authorities must stop treating critics as if they are criminals or a threat to national security. They must be released and the charges against them must be immediately dropped in the condition where there is an insufficient evidence under international criminal standard.” said Piyanut.

The detentions increase the number of pro-democracy protesters detained pending trial over demonstrations since the beginning of 2020 demanding the resignation of the prime minister and his cronies, constitutional amendments and monarchy reform.

Three anti-government leaders have been moved from Bangkok Remand Prison to Thon Buri Remand Prison, where they are being held in quarantine.

Corrections Department chief Ayut Sinthoppan said on Tuesday that Panupong “Mike’’ Jadnok, Jatupat “Pai Dao Din’’ Boonpattararaksa and Piyarat “Toto’’ Chongthep were transferred to Thon Buri on Monday to ease overcrowding at Bangkok Remand Prison.

Prison officials took the three suspects for records and health checks before taking them to the prison’s reception centre for 14-day quarantine as part of Covid-19 prevention measures.

The suspects were put in separate detention rooms. However, there were other prisoners in their rooms, the department chief said.

Mr Panupong and Mr Jatupat are charged with lese majeste and other offences and Mr Piyarat with violating the emergency decree. All charges stem from their roles in anti-government rallies. They have been denied bail

During their trial, prison officials from Bangkok Remand Prison would go to Thon Buri and then escort the defendants to the court, Mr Ayut said.

Asked if there were any worries about supporters of the protest leaders gathering at Thon Buri Remand Prison, he said there was tight security in the area around the prison 24 hours a day.

Prison authorities were not allowing the suspects to have visitors, because they were quarantined under Covid-19 measures, he said.

Another protest leader Panusaya “Rung’’ Sithijirawattanakul had been sent to the Central Women's Correctional Institution, the department chief said.

Soraya Rit-aram, director of the women's prison, said on Tuesday that Ms Panusaya was also in 14-day quarantine. Only lawyers were allowed to visit her, Ms Soraya said.

Justice Minister Somsak Thepsutin on Tuesday confirmed he has plans to expand the Bangkok prison compound for political prisoners, to ease overcrowding when relatives and fellow demonstrators come visiting.

However, he had to look further into the details first.
