Spokesperson for the candidates, Brian Boma, alleged that the appointment of RO Willie Ropa and the assistant RO Samuel Kewa, for Anglimp South Waghi, was illegal.
He claimed the appointments were done through the incumbent MP for Anglimp South Waghi, Joe Komun Koim.
Before counting takes place, the appointment of Ropa and Kewa must be revoked, says Boma.
After presenting their petition to the Jiwaka Election Steering Committee, the candidates said the committee confirmed that Ropa and Kewa did not apply for the position of the returning officer and ARO.
Boma also raised concern that Jiwaka is a new province and legal processes should be followed.
He said if their call was not adhered to, they will be protesting to stop the counting.
