Otago University Students Association (OUSA) president-elect Jo Moore says she will challenge a ruling disqualifying her from becoming next year's president.
Miss Moore, a commerce student, said she was stunned by the decision which she was told about at a meeting yesterday.
She said she understood a complaint she was within 20m of a polling facility during voting had been upheld, and it was also suggested she had overspent the $1000 limit for election campaigning.
She disputed the claims and said she had all receipts for election spending.
Miss Moore survived two previous appeals against her presidency after winning the election by 122 votes over the closest of seven other candidates.
She said she had no chance to provide any evidence in the appeals to her presidency and was unaware a further appeal was made.
She was seeking legal advice to challenge and overturn the disqualification process.
OUSA president Simon Wilson said he would not give reasons for the decision, or comment on criticism of the appeals process.
Edwin Darlow, the next highest-polling candidate, would become president next year, he said.
