Vanuatu's Supreme Court has ruled in favour of the opposition after the Speaker initially declared their motion of no confidence was not in order.
Judge Dudley Aru ruled that the motion is in order and will be heard on 4 December.
He said the court could not interfere with parliamentary matters unless required to do so.
The Daily Post newspaper reported that politicians and their supporters who packed the court room spilled out with smiling faces after the ruling.
The Leader of Opposition Ishmael Kalsakau welcomed the ruling and said the case should not have dragged on this far.
