Citing its inability to conduct primaries before the stipulated deadline, the Independent National Electoral Commission (INEC) had barred the ruling party from participating in the election in the north-west state.
On January 25, a federal high court in Abuja held that INEC was right to have delisted names of candidates APC presented for the elections.
The court ruled in favour of the commission, stating that the APC failed to conduct primaries within the required period.
But a 3- man panel of the appellate court held that the trial court lacked the jurisdiction to have entertained the suit, that it was an abuse of court process.
The panel said the suit at the federal high court was filed out of time.
It said while the electoral act provided for 14 days to institute a suit after the cause of action had arisen, the suit was filed 15 days after, making the action illegal.
The appellate court ruling comes one week after Abubakar Malami, attorney-general of the federation, asked INEC to postpone elections in Zamfara state.
At a press conference in Abuja on Thursday, Mahmood Yakubu, INEC chairman, had insisted that APC in Zamfara would not field candidates.
Abdulaziz Yari, governor of the state, had threatened that elections will not hold in Zamfara without APC participating in them.
