The Code of Good Practice in Electoral Matters requires that it “must be possible to annul the entire election or merely the results for one constituency or polling station. In the event of annulment, a new election must be called in the area concerned.”69 In principle, the annulment of elections should be limited to the electoral units affected by the irregularities.70 This means that if the irregularities that have affected the outcome of the election in one or more constituencies are limited to certain polling districts, only the election in these polling districts can be annulled and subject to a new election, unless a repeat election in these polling stations would not guarantee a fair election result due to possible tactical voting.71 Conversely, if the irregularities have affected the outcome of the election in all polling districts and constituencies, then the whole election must be annulled.
