United Nations Draft Model Law on Legal Aspects of Electronic Data Interchange

[U.N. document A/CN.9/406, November 1994]

Article 7: Original


Where a rule of law requires information to be presented in its original form, or provides for certain consequences if it is not, a data message satisfies that rule if:

(a)that information is displayed to the person to whom it is to be presented; and

(b)there exists a reliable assurance as to the integrity of the information between the time wehn it was first composed in its final form, as a data message or otherwise, and the time when it is displayed.

(2) Where any question is raised as to whether subparagraph (b) of paragraph (1) is satisfied:

(a) the criteria for assessing integrity shall be whether the information has remained complete and unaltered, apart from the addition of any endorsement, and any

change which arises in the normal course of communication, storage and display; and
(b)the standard of reliability required shall be assessed in the light of the purpose for which the infomration was composed and in the light of all the relevant circumstances.

Article 8: Admissibility and evidential value of data messages

(1) In any legal proceedings, nothing in the application of the rules of evidence shall apply so as to prevent the admission of a data message in evidence:

(a) on the grounds that it is a data message; or,

(b) if it is the best evidence that the person adducing it could reasonably be expected to obtain, on the grounds that it is not in its original form.

(2) Information presented in the form of a data message shall be given due evidential weight. In assessing the evidential weight of a data message, regard shall be had to the reliability of the manner in which the data message was generated, stored or communicated, to the reliability of the manner in which the integrity of the information was maintained, to the manner in which its originator was identified, and to any other relevant factor.

(3) Subject to any other rule of law, where subparagraph (b) of paragraph (1) of article [7] is satisfied in relation to information in the form of a data message, the information shall not be accorded any less weight in any legal proceedings on the grounds that it is not presented in its original form.

For a discussion of the original requirements at common law, see: Ewart, "Documentary Evidence: The Admissibility at Common Law of Records Made Pursuant to a Business Duty" (1981), 59 Can. Bar Rev. 52. In his article, "Documentary Evidence: The Admissibility of Documents Under Section 30 of the Canada Evidence Act" (1979-80), 22 C.L.Q. 189 at 193, note 11, Ewart states: "At common law, a record containing hearsay could be used as evidence of the truth of its contents only if it was (i) an original entry, (ii) made contemporaneously with the event recorded, (iii) in the routine, (iv) of business, (v) by a person since deceased, (vi) who was under a duty to do the very thing and record it, and (vii) who had no motive to misrepresent." (The two articles appear as chapters of his 1984 work, Documentary Evidence in Canada.)
