through the property in question, the party can be impleaded so as to safeguard his interest if the proposed party is a bona fide purchaser of property during the pendency of the suit. If he is a bona fide purchaser for a valuable consideration then his right will be affected, in the subject matter of the suit and the sale transaction entered between the second defendant and the proposed party has to be decided in the same trial. So, in order to avoid multiplicity of proceedings, the second plaintiff who sold away the property during pendency of litigation must not have any interest in the proceedings. Whether the proposed party is a bona fide purchaser for a valuable consideration or not, and whether he has got semblance of right in respect of the schedule property, are to be decided only after he comes on record, and without his presence, effective and appropriate orders cannot be passed in the proceedings. So, in these circumstances, in order to avoid multiplicity of proceedings, and to decide the issues involved in the suit effectually between the parties, the presence of proposed party is necessary. The trial Court, without considering these aspects, dismissed the petition, and hence, the impugned order is set aside.
