THE ANC in KwaZulu-Natal announced that it will appeal the judgement made by the high court on Tuesday.
The Pietermaritzburg High court nullified the party's 2015 provincial elective conference.
ANC spokesperson Zizi Kodwa said the decision would have to be made by the party's national leadership.
"The PEC of KZN must allow national space to deal with the issue, working of course with the executive committee.
Our lawyers are still going through the court judgment.
We have a responsibility to appreciate the political ramifications, but we have not yet met with the provincial leadership," Kodwa said.
The ANC in KwaZulu-Natal held an early conference in 2015 that saw chairperson Senzo Mchunu ousted and replaced by Sihle Zikalala.
Disgruntled branch leaders had argued that the holding of the provincial conference was unlawful, as it had not been requested by at least one-third of the branches in the province.
They also claimed it was rigged, with several irregularities relating to branch membership audits, insufficient time allowed for appeals against the auditing process, discrepancies in the accreditation of delegates, and the manipulation of voting results at the conference.
The KwaZulu-Natal High Court in Pietermaritzburg ruled that the elective conference, and all decisions taken at the conference, were unlawful and invalid.
It also ordered the provincial leadership to pay the costs of the applicants.
