“Today, we have heard Smt.Rajasree, learned counsel appearing for the respondent Union at length. During the course of hearing, it is also pointed out that the attempt of the appellant is only to cause the evidence to be re-appreciated, which is not possible in view of the law declared by the Apex Court in [(2014) 6 SCC 434] and such other binding precedents. The learned counsel submits that there was no proper compliance of Section 17B as well, which however, is sought to be disputed by the learned counsel for the appellant, in reply. There is no dispute with regard to the fact that all the five workmen represented by the Union have now crossed the age of superannuation and as such, the residual question is only with regard to the back wages (50%) ordered to be paid.
