Section 319 Cr.P.C. should not be mechanically exercised merely on the ground that some evidence had come on record implicating the person sought to be added as the accused in the case. P.W.1 the injured has, not doubt, deposed before court that he was beaten with an iron rod by the petitioner and he had attempted to ward off the blow with his hand and the blow struck his shoulder. But P.Ws 2,4,5, and 6 have not stated those overt acts which were spoken by P.W.1. They have only mentioned the name of the revision petitioner as one among those who had assaulted PW.1. Moreover, the names of P.Ws 2,4,5 and 6 do not figure in the F.I.R. Under these circumstances, the court below, not was justified in exercising the power under Section 319 at the fag end of the trial so as to add the revision petitioner as an accused person. When the precious time and energy of the court have already been arrested and the arraignment of the petitioner will also entail a denovo trial so far as he is concerned.
