The Cambodian Center for Human Rights has asked Prime Minister Hun Sen to examine "irregularities" in the proposal of a governor to move several hundred families off land in Kampong Thom province.
Villagers told the CCHR in a public forum in March they had been leaked documents that showed plans by Governor Nam Tum to move families off land they legally occupy.
The rights group said in a letter to Hun Sen the villagers feared the governor would kick them off more than 3,000 hectares of land in order to sell it to a rubber company.
Governor Nam Tum said the people were living on state land.
