Minister Vohor is facing serious criminal charges in the bribery case where 18 MPs are defendants.
Justice Sey issued the direction upon the defendants request through his lawyer advising the minister will not be present when the court convenes, as Vohor will be overseas on official duty.
But Justice Sey ordered Vohor and the 17 defendants to refrain from travelling abroad, as well as attend all court sessions in the two weeks sitting and to be punctual.
Six political party presidents will stand trial as Supreme convenes the bribery case hearing in September.
Presidents of the Green Confederation, Vanuatu Republican, the Vanuatu Liberal, Namage Aute, the Rural Development Party and the Union of Moderates are all defendants in the bribery case.
