“8. On conjoint consideration of the above leads to the conclusion that, on the face of the approval petition of the appellant / Management qua the termination of service of the respondent / workman having been rejected by the competent authority by a speaking order and further the said order having been confirmed by this Court in writ petition and this writ appeal, the next question is, what would be the consequence thereof. Since learned Single Judge attempted to balance the equities between the parties and for that purpose concession was given on behalf of the workman that he forgoes the actual payment of arrears towards back wages for the said period, we find that, the said concession cannot be stretched to the extent that the said period is to be counted as non-pensionable service. The Management cannot be heard contending that, in absence of any actual payment of arrears, there will not be any payment to Pension Trust Fund and that is how that period has to be excluded as nonpensionable service. We are of the view that the concession on behalf of the workman cannot be understood to that extent.

In a given case, either Labour Court or the Writ Court, in the facts of the case may exercise discretion, on permissible parameters, of granting / not granting back wages but exercise of that power under no circumstances can be read as exclusion of that service as non-pensionable service as sought to be canvassed on behalf of the appellant / Management. We make it clear that even in those cases, where back wages is not granted for valid
