He said many commission of inquiries have been set up and recommendations given but they have yet to be implemented.
Yama added that a lot of money had also been spent and still nothing has come forth.
"When will we see some people go to jail or face charges as a result of recommendations from the inquiries?
"Many of the people implicated in the inquiries have stolen millions of kina from the people of PNG and yet have not been arrested."
"Every time we ask for a Commission of inquiry yet no results are being implemented".
