The Supreme has upheld the election of Nyesom Wike of the Peoples Democratic Party (PDP) as governor of the oil-rich Rivers State.
The court gave the ruling Wednesday but did not provide reasons for its judgment.
It said detailed reasons for the verdict would be provided on February 12.
The Court of Appeal had on December 16 affirmed the judgment of the Rivers Governorship Election Tribunal.
The appeal court had ruled that Mr. Wike was not validly elected.
The Rivers Tribunal had earlier on October 24 nullified Mr. Wike’s election.
The tribunal, which delivered its ruling in Abuja, also ordered that a fresh governorship election be conducted in the state.
After the tribunal’s ruling, the governor headed to the Court of Appeal, saying the judgment was untenable.
The petition challenging the election of Mr. Wike as Rivers State Governor was filed by Dakuku Peterside, the candidate of the All Progressives Congress, in the election.
The Rivers governorship election, which was criticised by local and international observers, witnessed the largest amount of violence both in its build-up and after the elections.
