The court has consequently ordered a fresh election within 90 days.
Anambra Central Senatorial district is regarded as one of the most keenly contested in the country having a former Governor Chris Ngige, the National Chairman of the All Progressives Grand Alliance (APGA), Chief Victor Umeh and of course Mrs Ekwunife.
The appeal was filed by Mr Umeh of APGA.
Delivering the judgment, Justice Datijo Yahaya said that the election of Mrs Ekwunife on March 28, 2015, did not meet the prescription of the Electoral Act.
Reacting to the judgment, Mrs Ekwunife said she had accepted the court’s decision and was ready for the fresh election.
Mrs Ekwunife before the nullification of her election was the Chairman of the Senate Committee on Oil and Gas Downstream.
