The Koh Kong provincial court on Thursday dropped the case against Alejandro Gonzalez-Davidson, the founder of environmental NGO Mother Nature.

Gonzalez-Davidson had been charged with being an accomplice in "threatening to cause destruction, defacement or damage" and inciting others to do the same under articles 29 and 424 of the Criminal Code.

“The trial judges ruled to free Alejandro Gonzalez-Davidson from the charges,” said Koh Kong Provincial Court spokesperson Un Sovantheany.

The case centred around the alleged repeated obstruction of sand-dredging operations.
