bound by the findings therein. According to the learned counsel, in the light of the judgment of this Court in Peirce Leslie India Ltd. v. Secretary, C.I.T.U. (2006 (1) KLT 869) , the statutory claim, if any, of the additional fourth respondent cannot be relied on to negative the claim of appellant against a vacancy. We are unable to agree, not only for the reason that additional fourth respondent is a statutory claimant under Rule 43 of Chapter XIV A of KER and also for the reason that she is not a party to the previous judgments. Learned counsel for the appellant contended that the claim of appellant is under Rule 51A of Chapter XIV A of KER and therefore, he has a claim which is superior to additional fourth respondent. We find that such an argument was not raised before the learned Single Judge or has not been dealt with in the judgment. This being a mixed question of law and fact, if the appellant wants to challenge the same, the proper course for him is to seek review of the judgment instead of urging the same in an appeal for the first time.
