The two activists have been sentenced to four years in prison for royal defamation because of their criticism of Gen Prayut Chan-o-cha's administration for expanding the King's power. The sentence was reduced to two years and eight months, and they were later granted bail pending appeal.

On 27 June 2023, Thai Lawyers for Human Rights (TLHR) reported that the Thonburi Criminal Court delivered the verdict in the case of Chukiat “Justin” Saengwong and Wanwalee “Tee” Thammasattaya who were indicted under the royal defamation law over their speeches on 6 December 2020 during a protest at the King Taksin the Great Monument.

The complaint against the two activists was filed by Chakrapong Klinkaew, leader of the royalist group People Protecting the Institution.

The two activists were found guilty of violating the royal defamation law, resulting in a four-year sentence for each. The sentences were reduced to two years and eight months due to their helpful testimony.

The court concluded that Chukiat delivered a speech discussing the seizure of power from King Taksin the Great, resulting in the establishment of the current ruling dynasty. He also criticized the government’s use of Section 112, the royal defamation law, to silence the people, fearing that they would speak the truth. Chukiat added that even if Thailand claims to be a democratic country with the king as head of state, the government denies the rights of those who call for righteousness.

Chukiat also mentioned Prime Minister Prayut Chan-o-cha, who accused him of wearing attire that insulted the king, although it was intended to mimic a foreign singer. He also addressed the status of the institution of the monarchy, which cannot be questioned, and emphasized the need for protesters to demand reform of the monarchy due to the excessive exercise of royal power, distinguishing it from the monarchies in other countries.

Chukiat is well known for his speeches and public appearances in protests where he wore crop tops. The nickname ‘Justin’ is after Justin Bieber, a famous singer who also wears crop tops.

In her speech, Wanwalee discussed the fact that the King serves as the Supreme Commander of the Royal Thai Armed Forces as stipulated in the constitution, granting him the power to lead the military. She also raised the issue of royal involvement in ratifying coups d'état and influencing the work of the cabinet ministers.

In this case, the two activists denied all charges. The court scheduled hearings for prosecution witnesses on 8 -9 February, 19 July, and 2 August 2022 and for defence witnesses on 3, 10 and 31 March 2023, prior to delivering the verdict.

The TLHR said that both have been granted bail at 300,000 baht each pending appeal.
