lands in question are in the possession of protected tenants and it was the specific finding of the Land Reforms Tribunal that there was no material to show that the third parties in possession are tenants. The Land Reforms Appellate Tribunal, hence, cannot be considered wrong in concluding that the possession of such third parties, the manner of or right to possession of whom was not explained, has to be considered as an encumbrance which can be avoided by refusing to accept the surrender of such lands by the declarants. The revision petitioners have not placed any further material before this Court to deviate from the conclusions of the Land Reforms Appellate Tribunal in exercise of the restricted revisional jurisdiction of this Court. Even if the surrender of such lands is permissible, and not prohibited, the respondent cannot be compelled to accept such surrender in the light of the statutory provisions and on the admitted factual position, the revision has to, therefore, fail.
