Phnom Penh Municipal Court yesterday questioned a CPP spokesman who previously worked at the Cambodian Centre for Human Rights with jailed opposition leader Kem Sokha.
Investigating judge Ky Rithy questioned Chhim Phalvirun for almost three hours over his previous work at the CCHR and over the treason charge against Mr Sokha.
Mr Phalvirun declined to reveal the line of questioning in order to avoid affecting court procedures.
“The court asked me questions related to CCHR and the crime charged against Kem Sokha,” he said. “I answered what I knew. What I didn’t know, I told the judge as much.”
Last month, Mr Phalvirun was summoned as a witness in the case of Mr Sokha, who was charged with treason in September over an alleged attempt to overthrow the government.
Mr Sokha was denied bail by the Appeal Court last week.
The CCHR was founded by Mr Sokha in 2002 before he returned to politics in 2007. During that time, Mr Phalvirun was deputy of the centre.
In 2006, former employees of CCHR accused Mr Sokha of committing corruption at the organisation, which was funded by the US-based International Republican Institute; Mr Sokha denied the allegations.
Mr Phalvirun, who is also director of the Institute for Civic Education, said he appeared on his own behalf, not any political party. The questioning was unrelated to the case of corruption at CCHR, he added.
“My answers are based on reality because I value justice,” Mr Phalvirun said, adding he would give more answers if required by the court.
In December, Prime Minister Hun Sen affirmed that the CCHR would not be shut down after an investigation by the Interior Ministry concluded it was not linked to an attempted colour revolution led by the dissolved CNRP.
The investigation was undertaken after Mr Hun Sen suggested it should be closed because it was founded by Mr Sokha.
