4. The learned counsel for the appellants contend that the first appellant has been in possession and enjoyment of the property and perfected title to the property. It is not in dispute that the property belongs to the Government and it is an assigned land and it cannot be alienated. The specific case of the first defendant in the suit is that the suit property was sold on 01.07.1962 to the second defendant and the second defendant in turn sold the land to the first defendant in 1965 and therefore he has been in continuous possession and enjoyment of the property. The possession, if at all to be considered for the first defendant, can only be from 1965 onwards, when he has purchased the property under alleged agreements of sale. Unless and until the right of the second defendant is established, the first defendant cannot get any rights. The second defendant, who was the purchaser of the property from the plaintiff under the agreement of sale, dated 01.07.1962, did not prefer any appeal against the original judgment of the trial Court nor did he participate in the trial Court pleading the agreement in his favour. Unless and until the purchase by D.2 is established by himself by going into the box and by filing a suit for specific performance or obtaining a sale deed, his oral evidence can have no relevancy and any amount of effort made by the first defendant can have no result.
