Respondent claiming full backwages which has been awarded. The award of the Industrial Court has been sustained by the learned Single Judge under the impugned judgment. We may notice that in the reply filed before the Industrial Court, the Management had not taken any plea that the Petitioner was gainfully employed and therefore was not entitled to backwages. Once such a plea was raised, the onus to prove that he was not gainfully employed would have rested on the Petitioner. In the absence of such plea, we are unable to find any fault in the order of the Industrial Court. We may also notice here that the Appellant had not raised any specific plea even in the Writ Petition where he challenged the order of the Industrial Court. Now, we cannot permit the Appellant to raise such a plea during the course of argument when such a plea has been taken for the first time in the Letters Patent Appeal. No merit in this Appeal. Hence, dismissed.
