ASUU lawyer Femi Falana filed papers at the Court of Appeal in Abuja on Friday seeking to set aside the judgment by the National Industrial Court, which had ruled on Wednesday the Academic Staff Union of Universities (ASUU) should end the strike.

A hearing will be held at a later date.

Lecturers from public universities, used by the majority of students in Africa's most populous country, routinely strike for better pay.

ASUU is demanding an increase in pay and allowances and better funding for the country's education sector. The government wants lecturers to go back to work while negotiations continue.

Cracks have appeared within ASUU, however, with medical lecturers applying to the labour ministry to register a separate trade union and return to work.
