The Solomon Islands prime minister, Manasseh Sogavare, says those who make uninformed comment on issues including the Julian Moti saga can be sued for defamation.
Mr Sogavare issued the warning amid widespread public criticism of his plan to lift the suspension of Mr Moti as attorney-general while Mr Moti is wanted by Austalian police for alleged sex crimes.
The prime minister has taken issue with the condemnation of his plans by the opposition, Transparency Solomon Islands and the National Council of Women.
He says their reaction amounts to criminal defamation.
Mr Sogavare says the government maintains its stand that Australia's extradition attempt is politically motivated because a Vanuatu court had cleared Mr Moti and therefore there is no case to answer for in Australia.
