dated 25.04.2005 and find that P.W.3, Rajendra Kumar Sinha, who is father of the plaintiff had not put his signature upon the alleged agreement as a marginal witness or attesting witness. Absence of his signature upon the alleged agreement, it presumed that he had no personal knowledge about the alleged agreement to sell. As per Order 3, Rule 1 and 2, C.P.C., a power of attorney holder can appear, apply or act in any court, but such act cannot be extended to depose in the witness box. Power of attorney holder is not acting as a witness on behalf of the principal, but he can only represent the principal himself. Deposing in a witness box and being cross-examined is a personal act and cannot be done through an agent/ power of attorney holder. In the present case, it appears that suit for specific performance of contract has been filed by Alok Bhushan in whose favour the alleged agreement to sell was executed, but it is crystal clear that Alok Bhushan did not come forward before the court as a witness of the suit. However, in course of proceeding before the lower court, a special power of attorney has been submitted on behalf of the plaintiff by which the plaintiff empowered his father, Rajendra Kumar Sinha for act on his behalf. Here it is made clear that the alleged special power of attorney has not been marked exhibit in this matter by the lower court. I further find that on the basis of alleged power of attorney, the plaintiff's father Rajendra Kumar Sinha came before the court and stepped into the witness box as P.W.3 and gave his evidence in this matter. Now coming to evidence of P.W.2, Mihir Lal who claimed himself as an attesting witness of the agreement. This person has deposed in para-8 of his evidence by which he has stated that he reached at the house of plaintiff, Alok Bhushan where both the parties of the agreement were present and the agreement to sell was executed at the house of plaintiff where he and Prabodh Singh (one of the attesting witness P.W.1) were present except this nobody was present at that relevant point of time. Upon perusal of this evidence, it is crystal clear that when the agreement to sell dated 25.04.2005 was executed between plaintiff and defendant where the father of the plaintiff, Rajendra Kumar Sinha (P.W.3) was not present there. I find that being attesting witness of the agreement to sell this person did not support the fact that at the time of executing the agreement, the P.W.3 was present there. In my mind, the power of attorney holder does not have personal knowledge of the alleged matter of the plaintiff and therefore he can neither depose on his personal knowledge nor can he be cross-examined on those facts which are to the personal knowledge of the principal. Thus, it is crystal clear that the power of attorney holder has no power to depose in this matter on behalf of the plaintiff.”
