would show that widest of the powers have been invested with the Courts when it comes to the question of summoning a witness or to recall or re-examine any witness already examined. A reading of the provision shows that the expression "any" has been used as a pre-fix to "court", "inquiry", "trial", "other proceeding", "person as a witness", "person in attendance though not summoned as a witness", and "person already examined". By using the said expression "any" as a prefix to the various expressions mentioned above, it is ultimately stated that all that was required to be satisfied by the Court was only in relation to such evidence that appears to the Court to be essential for the just decision of the case. Section 138 of the Evidence Act, prescribed the order of examination of a witness in the Court. Order of re-examination is also prescribed calling for such a witness so desired for such re-examination. Therefore, a reading of Section 311 Cr.P.C. and Section 138 Evidence Act, insofar as it comes to the question of a criminal trial, the order of re-examination at the desire of any person under Section 138, will have to necessarily be in consonance with the prescription contained in Section 311 Cr.P.C. It is, therefore, imperative that the invocation of Section 311 Cr.P.C. and its application in a particular case can be ordered by the Court, only by bearing in mind the object and purport of the said provision, namely, for achieving a just decision of the case as noted by us earlier. The power vested under the said provision is made available to any Court at any stage in any inquiry or trial or other proceeding initiated under the Code for the purpose of summoning any person as a witness or for examining any person in attendance, even though not summoned as witness or to recall or re-examine any person already examined. Insofar as recalling and re-examination of any person already examined, the Court must necessarily consider and ensure that such recall and reexamination of any person, appears in the view of the Court to be essential for the just decision of the case. Therefore, the paramount requirement is just decision and for that purpose the essentiality of a person to be recalled and re-examined has to be ascertained. To put it differently, while such a widest power is invested with the Court, it is needless to state that exercise of such power should be made judicially and also with extreme care and caution.”
