The election of his deputy and Goilala MP William Samb was also nullified.
The decision was made in favour of Pangu Pati president Patrick Pundao who sought the ruling in his submission via his lawyer Justin Isaac.
However, both were re-elected to lead the party.
The court had ordered for a re-election facilitated by the registrar of political parties and candidates, Alphonse Gelu.
Complying with the court order, party executives and members convened at a meeting on Monday, October 1st, which was supervised and facilitated by Gelu.
