So far as the first question is concerned, it is not disputed that the appellant had received the money which was doe to him under the award and once the appellant had submitted to the award unequivocally and without reservation, it is not open to him to challenge the award. We have looked into the record and find that the appellant had submitted unequivocally to the jurisdiction of the Arbitrator. He also accepted the awarded amount without any reservation. Had the appellant desired to challenge the award, he could have reserved his right to do so, but no such reservation was made in the letters sent by him. In this view of the matter, there remains no manner of doubt about the fact that the appellant had submitted to the award and it does not lie in the mouth of the appellant to challenge the award. For these reasons, we reject the first argument of the learned counsel for the appellant.”
