service matter – Though the appellants may not be entitled to regular appointment as such it cannot be said that they will not be entitled to the minimum of the pay scale nor that they should not be continued till regular incumbents are appointed – The course adopted by the High Court is to displace one ad hoc arrangement by another ad hoc arrangement which is not at all appropriate for these persons who have gained experience which will be more beneficial and useful to the colleges concerned rather than to appoint persons afresh on ad hoc basis – . Appellants shall be entitled to the minimum pay scale and continuation in service till regular incumbents are appointed.
