A motion of no-confidence in the the government of Serge Vohor has been referred to the Vanuatu Supreme Court for a ruling on its legality.
The opposition presented the no-confidence motion, however the speaker Josias Moli said the courts needed to rule on whether it was legal given the government has been in power less than a year.
In October the parliament passed several controversial amendments to the constitution, including one barring votes of no confidence for one year after, and one year before, an election.
But the Opposition says the amendments have not been gazetted so they have no legal standing.
A Supreme Court hearing on the matter has not yet been scheduled.
