The head of service, Bukar Aji and the Attorney General of the Federation, Mohammed Adoke, have been dragged before the National Industrial Court, NIC, over the dichotomy existing between Higher National Diploma, HND, holders and university graduates.
The plaintiffs, civil servants under the auspices of the Nigerian Association of Technologists in Engineering, are seeking a total abolition of the HND and university degree dichotomy.
The suit was filed by Garba Bello, Adelaja Samuel, Jubril Kadiri, Christian Owolabi, Umechukwu Chuba and Fatima Mohammed on behalf of the association.
They are asking for the implementation of the federal government white paper which recommended the consolidation of emoluments of all public service employees in 2006.
Among the plaintiffs are level 14 public servants who say they have been denied further promotion because they were employed with HND qualifications.
The lawyer to the plaintiffs, Nnaemeka Ejiofor, argued that his clients have been victims of discrimination and want the NIC to invoke its powers and declare the policy unconstitutional.
The case, which came up for mention on Friday, has been adjourned till September 18 for hearing.
