Of all the 29 states where elections were held on Saturday, March 9, the commission has determined after the collation of results that elections are inconclusive in Adamawa, Bauchi, Benue, Kano, Plateau, and Sokoto states.
There's only one reason why INEC would declare an election inconclusive and refuse to announce a winner.
According to the "Margin of Lead Principle" contained in Sections 26 and 53 of the Electoral Act and paragraph 41(e) and 43(b) of the INEC Regulations and Guidelines, the commission cannot declare a winner if the number of cancelled votes can mathematically affect the outcome of the election.
So, for instance, if the margin of victory between the first-placed candidate and the second-placed candidate is 100, the number of cancelled votes cannot be any more than 99.
If the number of cancelled votes is 101, or higher, then the election will have to be declared inconclusive since the second-placed candidate can mathematically win the election if all 101 voters cast their votes for just that candidate.
Votes are most commonly cancelled during elections, as with these current ones, when the affected areas witness any form of violence or other factors that compromise the results.
Such factors could include over-voting, when number of votes cast is more than the number of registered voters, as well as INEC's failure to deploy election materials or officials to certain polling units.
The only way to resolve an inconclusive election is for INEC to conduct supplementary election in the areas where votes were cancelled.
The supplementary elections also have to be conducted within 21 days of the initial polls which is March 9, in this case.
Despite that the contest is usually mathematically between the top two candidates, all the candidates involved in the elections are still allowed to take part in the supplementary elections, and not just the top two as it would happen in a runoff election.
The first and second place battle in the affected six states is exclusively between the All Progressives Congress (APC) and the Peoples Democratic Party (PDP), with the PDP leading in five states and APC in one.
