ABC - A MEMBER of the PNG parliament has quit the ruling national coalition government because he opposes controversial amendments to environment legislation.
The amendments to the Environment Act effectively mean environmental permits granted for resource projects cannot be challenged in court.
Sumkar MP, Ken Fairweather, paid for a newspaper advertisement attacking the amendments.
He said the changes were bulldozed through parliament, are dictatorial and "against every principle a democracy stands for".
Mr Fairweather then resigned from the coalition and would be moving to the cross benches.
He was unavailable for comment.
The amendments have been widely criticised for robbing traditional landowners of their rights.
