Opposition lawmakers have written to Interior Minister Sar Kheng to question why procedures for issuing family books and other administrative documents have changed since the June commune elections.
The letter, which was passed through National Assembly president Heng Samrin, said local officials were not informed of why the changes were going ahead.
In the past, commune chiefs were responsible for issuing family books and signing off on a number of other administrative documents, but now the duties have been transferred to district authorities or commune police chiefs.
“People doubt the reason for the changes in policy after the 2017 commune election,” the letter said.
CNRP lawmaker Ky Vandara, who signed the letter, said the government must clarify why it has weakened the powers of commune chiefs.
“The CNRP has had 480 commune chiefs since the elections in June,” Mr Vandara said. “We want the Interior Ministry to explain why it has changed their powers.”
National Assembly spokesman Leng Penglong said he had received the letter and was reviewing it, declining to comment further.
CPP spokeman Sok Eysan said the issue was a matter for the Interior Ministry.
“I think it is good some duties were transferred to commune police chiefs because in some cases, commune police officials can investigate deeper than commune chiefs,” said Mr Eysan. “We cannot compare the procedures in the past to those we have now because they change based on circumstances.”
