The chairman of Transparency International Papua New Guinea says the Leadership Tribunal is not doing much to help erase corruption in the country.
The comment comes as cabinet minister Dr Puka Temu and Opposition Depury Leader Andrew Baing have been referred to the tribunal by the Public Prosecutor.
A number of high profile MPs have been investigated by the tribunal in recent months.
However Mike Manning says the referrals are not having a huge impact in the fight against corruption because the maximum penalty is a three year ban from public office..
"I think the sanctions are not enough really to seriously deter people. There are some people that have been referred for the second time already so clearly it hasn't been great."
Mr Manning says leaders should be banned for life from public office if they are found guilty of corruption.
