In DPP v. Me. Kewon, (1997) 1 Criminal Appeal 155, Lord Hoffman, applying Section 69 of the Police and Criminal Evidence Act, 1984 in relation to the inaccuracy in the time display in the computer print out, held:-
I shall for the moment assume that the inaccuracy in the time display meant that "the computer not operating properly". The question is therefore whether that was "such as to affect the production of the document or the accuracy of its contents". If the words are read literally, it did. The document said that the first test had occurred at 23.00 GMT when it was in fact 00.13 BST. As to one hour, the discrepancy is merely as to the way in which the time was expressed. 23.00 GMT is the same time as 00.00 BST. But the remaining 13 minutes cannot, I think, be dismissed as de minimis. The inaccuracy of the time reading therefore affected the accuracy of a part of the contents of the document. In my view, however, the paragraph was not intended to be read in such a literal fashion. "The production of the document or the accuracy of its contents" are very wide words. What if there was a software fault which caused the document to be printed in lower case when it was meant to be in upper case? The fault has certainly affected the production of the document. But a rule which excluded an otherwise accurate document on this ground would be quite irrational. To discover the legislative intent, it is necessary to consider the purpose of the rule. The first thing to notice is that Section 69 is concerned solely with the roper operation and functioning of a computer. A computer is a device for storing, processing and retrieving information. It receives information from, for example, signals down a telephone line, strokes on a keyboard or (in this case) a device for Chemical analysis of gas, and it stores and processes that information. If the information received by the computer was inaccurate (for example, if the operator keyed in the wrong name) then the information retrieved from the computer in the form of a statement will likewise be inaccurate. Computer experts have colourful phrases in which to express this axiom. But Section 69 is not in the least concerned with the accuracy of the information supplied to the computer. If the gas analyser of the Intoximeter is not functioning properly and gives an inaccurate signal which the computer faithfully reproduces, Section 69 does not affect the admissibility of the statement. The same is true if the operator keys in the wrong name. Neither of these errors is concerned with the proper operation or functioning of the computer. The purpose of Section 69, therefore, is a relatively modest one. It does not require the prosecution to show that the statement is likely to be true. Whether it is likely to be true or not is a question of weight for the justices or jury. All that Section 69 requires as a condition of the admissibility of a computer-generated statement is positive evidence that the computer has properly processed, stored and reproduced whatever information it received. It is concerned with the way in which the computer has dealt with the information to generate the statement which is being tendered as evidence of a fact which it states. The language of Section 69(1) recognises that a computer may be malfunctioning in a way which is not relevant to the purpose of the exclusionary rule. It cannot therefore be argued that any malfunction is sufficient to cast doubt upon the capacity of the computer to process information correctly. The legislature clearly refused to accept so extreme a proposition. What, then, was contemplated as the distinction between a relevant and an irrelevant malfunction? It seems to me that there is only one possible answer to that question. A malfunction is relevant if it affects the way in which the computer processes, stores or retrieves the information used to generate the statement tendered in evidence. Other malfunctions do not matter. It follows that the words "not such as to affect the production of the document or the accuracy of its contents" must be read subject to the overall qualification that the paragraph is referring to those aspects of the document or its contents which are material to the accuracy of the statement tendered in evidence.
In effect, substantially, Section 65B of the Indian Evidence Act and Section 69 of the Act in England have same effect. 293. Thus, in the context of Section 65B(2)(c) the condition that throughout the material part of the period to which the computer operations related, the computer was operating properly has to be complied with. However, this compliance would be on the principle laid down in Shepherd (supra) and as applied in Ana Marcolino (supra) and Me. Kewon (supra). Thus in our opinion, is the only practical way to deal with computer generated evidence unless the response is by way of a challenge to the accuracy of computer evidence on the ground of misuse of system or operating failure or interpolation. Such challenge has to be established by the challenger. Generic and theoretical doubts by way of smoke screen have to be ignored.
