The vagueness of the language of the application has precluded the trial Court, as also this Court to examine as to what is the purpose of summoning the witness afresh. There is indeed no doubt that the power of the Court under Section 311 Cr.P.C. is wide enough to recall and re-examine any witness during the course of trial subject to the condition that it is shown to the Court that examination of such witness or appraisal of such material is essential for the just decision of the case. But if the application itself is silent about the nature of the evidence to be brought on record, and there is no suggestive material produced before the Court to justify a prayer, then I am afraid, the Court is right in declining the same as there is nothing with the Court to evaluate it to arrive at a reasonable conclusion that such evidence is necessary for the just decision of the case.
