What the constitution says about elections and winners

According to the 1999 constitution, the winner (of this election) must have not less than one-quarter of the votes in at least two-thirds of all the local government areas of the state.

Hence, the winner of the Osun state governorship election must have not have less than one quarter of the votes in at least two-thirds of the local governments.

Run-off elections

A rerun election or a fresh election is one conducted, pursuant to an order of an Election Tribunal or Election Appeal Tribunal nullifying the result of a particular election, and  directing that a fresh election be conducted in place of the nullified or voided election.

A run-off election is one conducted between two leading candidates vying for a particular office, after the initial election amongst the many candidates contesting for that office has failed to produce a clear winner, who has won not only the majority of the votes cast in the election, but who also has  fulfilled the requirements of the Electoral Act to be declared a winner and given a certificate of return.
