9. As we find that in an identical situation when in the case of Mr.Beg the respondents have admitted to have erroneously fixed his pay scale under the S.S.Committee at par with counterparts in DVB/DESU and what has been allowed is the revised pay scale, it holds good for all the categories, which were subject matter of the decision of the Apex Court and rather as a model employer the revised pay sales should have been suo motu granted by the respondents to the applicants. However, the same has been withheld leading to unnecessary litigation. In such view of the matter, this erroneous grant of pay scale holds good for the set of employees, i.e., applicants in the TAs and we have no hesitation to hold that the respondents have deprived applicants S.S.Committee’s pay scales, as revised in case of their counterparts in DVB/DESU. The Apex Court in Union of India v. Satyabarth Choudhry (2010) 1 SCC (L&S) 475 held the differential treatment in the matter of pay scales amounts to an illegality.
