The Vanuatu Magistrate's Court is due to decide today whether an alleged conspiracy claim against deputy Prime minister Joe Natuman is to go before the Supreme Court.
Last month, the chief magistrate sought the Supreme Court's view on the merit of the conspiracy claim.
Mr Natuman is facing charges of conspiracy to defeat the course of justice when he was prime minister and minister for police.
It concerns his suspension of investigations into a mutiny case involving rival senior high ranking police officers.
The then acting police commissioner, Aru Maralau, who was acting on instruction from his minister, is facing the same charges.
Jailed politician, Moana Carcasses Kalosil is the complainant in this case.
