The qualifications for the post of Junior Plant Attendant (J.P.A.), were prescribed through B.P.Ms.No.1048, dated 23.09.1989, as pass in 10th class and I.T.I., or Vocation Course in Electrical Trade. Through proceedings, dated 06.12.1996, such of the casual workers, who have fulfilled the qualifications stipulated in B.P.Ms.No.1048, dated 23.09.1989, were regularised as J.P.As. The respondents filed W.P.No.8389 of 2002, complaining that the stipulation of qualifications in B.P.Ms.No.1048, dated 23.09.1989, is illegal, arbitrary and discriminatory and that their services ought to have been regularised with effect from 06.12.1996, on par with other candidates. The writ petition was opposed by the appellants by filing a detailed counter-affidavit. A learned Single Judge of this Court allowed the writ petition, directing that the services of the respondents shall be regularised with effect from 06.12.1996, and their scales of pay shall be determined on notional basis. It was, however, directed that they shall not be entitled for arrears of differential wages. The appellants feel aggrieved by the orders passed by the learned Single Judge.
