A Cambodian-American lawyer and dozens of members of a now-dissolved opposition party were convicted of treason on Tuesday in a trial that was the latest move to tame all opposition to the long-running rule of Prime Minister Hun Sen. Lawyer Theary Seng and most of the other defendants had been charged over a failed attempt by the leader of the defunct Cambodia National Rescue Party to return from exile in 2019. Cambodian authorities blocked Sam Rainsy’s return and alleged the 60 defendants were involved in organising his trip, which Theary Seng and the others have denied. Cambodian courts are widely believed to be under the influence of Hun Sen, whose authoritarian style of rule has kept him in power for 37 years. The Cambodia National Rescue Party was his party’s biggest rival before it was disbanded by a court ruling just ahead of national elections in 2018 that resulted in a clean sweep by Hun Sen’s Cambodia People’s Party. The Phnom Penh Municipal Court found Theary Seng and most of the others guilty of conspiracy to commit treason, defence lawyer Choung Chou Ngy said. Theary Seng was sentenced to six years in jail, and the others received sentences of five to eight years. Many of the 60 defendants earlier fled into exile or went into hiding, and it was not immediately clear how many appeared in court for the verdict on Tuesday. Theary Seng stood outside the court as the verdict was announced, saying she wanted her arrest to be public and “not in the shadow”. Media saw at least three police officers approach Theary Seng, hold her hands and body, and push her into a waiting police truck soon after the verdict came. Cambodia ‘playing with fire’ by cosying up to China, says Sam Rainsy She was garbed as Lady Liberty, in a light green gown and a crown with “Freedom” written on it, and from time to time, she raised up her imitation torch and shouted “free the political prisoners”. She has worn thematic costumes to her court sessions to publicise her belief that Cambodia is not a democratic nation and the trial is unfair. She told reporters she was ready for a “sham” guilty verdict. “I am ready and prepared to go to the notorious Cambodian prison for my political opinions, for my beliefs, for my belief in democracy, for my belief in freedom,” she said. “I am ready to pay the price of prison in order that I live out my conscience and my belief in freedom and justice.” Choung Chou Ngy, who represents Theary Seng but not the other defendants, said he plans to file an appeal. He said the defendants who got five-year terms had their sentences suspended. But those with sentences of six to eight years were ordered jailed, and the judge ordered police to find those who were sentenced in absentia so they could face justice. The disbanding of the Cambodia National Rescue Party, its removal from the ballot, and a government crackdown on media and independent voices paved the way for Hun Sen’s party to sweep the 2018 elections and claim every seat in the National Assembly. He has repeatedly stated his intention to stay in office until 2028 and has endorsed one of his sons to succeed him. Sam Rainsy, Hun Sen’s main political nemesis, has been in exile since 2016 to avoid serving prison sentences on defamation and other charges he says are politically motivated. The trial of Theary Seng and her co-defendants began in 2020 but was suspended until December 2021 due to coronavirus restrictions. Initially, nearly 130 defendants were named and the proceeding were split into three trials for manageability. In a related case in March, the court convicted 21 people of treason and related charges for their nonviolent political opposition to Cambodia’s government. Seven exiled leaders of the Cambodia National Rescue Party, including Sam Rainsy, received 10-year prison terms in absentia. Another 13 defendants were ordinary party supporters whom the court ordered to serve more than three years.
