Introduction to police Investigation
  1. It is generally seen that when the police begins investigation into a criminal case that has been reported, it depends substantially on the information gathered either from the scene of crime or the circumstances attendant thereupon or the facts collected from the individuals involved, be they witnesses who are directly privy to the necessary background facts or otherwise conversant with the relevant material or even the persons who are suspected (or accused) to be involved. The inputs received from the last mentioned category – that is, the suspects or the persons accused – are, of course, generally inadmissible unless they can be introduced in evidence, if so permissible, illustratively under Section 27 of the Evidence Act. After the investigating agency has gathered all the requisite background facts, and has collected sufficient evidence to substantiate it during inquiry or trial before the criminal court, it presents its case in the form of a report under Section 173 Cr. PC (” chargesheet “) seeking trial of such persons whose involvement is borne out, in its opinion, from the material submitted therewith. This, ideally, would be a stage where the investigating agency (from which the prosecution takes over) presents its case in entirety leaving out, in the interest of fairness of the process, nothing from the gaze of the court. But, experience also shows that during the course of the trial, some of the facets of the case are either rendered redundant or irrelevant (for example on account of duplication or being repetitive) and, therefore, fall on the side making it unnecessary for the prosecutor to add to the formal production of evidence in such regard, this particularly in cases where the prosecution rests its case on direct evidence.
  2. It is not the requirement of criminal jurisprudence that the prosecution must prove each nugget of the facts as alleged in the beginning by the charge-sheet in order to succeed. The court is eventually called upon to take a view, and give its decision, on all the facts which are actually proved during the trial. In case the prosecution has omitted to bring on record formal proof of certain facts which the court perceives to be crucial, there are ample powers in the Code of Criminal Procedure to call for further evidence in such respect. [see, Artile on  Sections 311 and 391 Cr. PC).
  3. A criminal case is not like a jigsaw puzzle, such that it cannot succeed unless all the pieces of the maze are in place. This is not so even in cases founded on circumstantial evidence, what to say of cases supported by direct evidence. If the prosecution does not have any direct proof and depends on proof of circumstances, it has to bring home, to the satisfaction of the court, all such circumstances that collectively form a complete chain pointing towards the guilt of the accused. The prosecution may have begun the quest with a large volume of facts but may end up proving less than what those gamut of circumstances were and, yet, if the circumstances that are proved beyond all reasonable doubts and are sufficient to point towards the complicity of the accused, a conviction may still be called for on such basis; this, notwithstanding the fact that some of the circumstances have remained unproved .
    Introduction to police Evidence   

Section 24 of the Evidence Act contains a clear prohibition against consideration of any statement made by an accused (or suspect) to the police during investigation. Sections 25 and 26 of the Evidence Act add further to the said very cardinal principle. Section 27 of the Evidence Act carves out a very small window for some part of such statement to be looked into. It says in clear terms that only “so much of such information” as has been received from the accused by the police “may be proved” as “relates distinctly to the fact thereby discovered”. It is expected that a fair investigating police officer would scrupulously record whatever is disclosed to him by the suspect during interrogation. If such statement (or information thereby given) leads to discovery of any fact only so much of the statement (or information) may be presented to the court as evidence as is relevant and admissible. But, the disclosure statement in its entirety cannot be looked into by the court. To use such statement, that too in entirety, as the touchstone to ascertain the veracity of the prosecution evidence is something unheard of – totally unacceptable. Conversely, the prosecution evidence cannot also be used by the court to record a satisfaction that the statement given by the suspect to the police (noted for such exercise in entirety) even beyond what is admissible under Section 27 of the Evidence Act was truthful or otherwise. Such reasoning, to my mind, is taboo and cannot be adopted.
