During the 2015 General Elections in Tanzania, the Appellants were registered as voters in the Bunda Urban Constituency. On October, 25th 2015 which was the “Election Day”, they voted to elect a Member of Parliament for their Constituency. The first Respondent was declared by the Returning Officer to have scored the majority of votes, and therefore, the duly elected Member of Parliament for the Bunda Urban Constituency. The Appellants were aggrieved by the election which they considered to have been unfair. They accordingly filed a petition in the High Court of Tanzania. The petition was opposed by the three Respondents.
