The Center for Human Rights (CCHR) alleges it plans to give a motion to King Sihamoni next week to pardon jailed human rights activists.
At least four activists are imprisoned on defamation charges against the government. Mr. Yeng Virak, Community Legal Education Center's director was released on bail last week.
CCHR started the motion and gathers 75,000 signatures from local people. CCHR spokesman Ou Virak says that this number can increase to 100,000.
A palace official says on condition of anonymity that he has received this information.
Cambodian People's Party legislator Chiem Yiep supports this idea if King Sihamoni agrees to pardon them, and he says that Prime Minister Hun Sen used to be linient.
Government spokesman Khieu Kanharith dismisses the criticisms saying in Cambodia there are more than 2,000 NGOs, and the newspapers are still criticizing the government.
