  1. The Admissibility of Electronically Generated Evidence in a Court of Law Presented by Advocate Roux Krige

  2. THE ADMISSIBILITY OF EVIDENCE EMANATING FROM ELECTRONIC EQUIPMENT

  3. ELECTRONICALLY EMANATED EVIDENCE MAY BE ADMITTED IN EVIDENCE IN A CRIMINAL COURT UNDER THE: • Common Law • Criminal Procedure Act No 51 of 1977 • Section 3(1) of the Law of Evidence Amendment Act No 45 of 1988 (Hearsay) • Electronic Communications and Transactions Act No 25 of 2002 (ECT Act)

  4. DEFINITION OF DOCUMENT UNDER THE COMMON LAW • Any written thing capable of being evidence. See R v Daye 1908 KB 330 at 340; • “Everything that contains the written or pictorial proof of something. It does not matter much of what material it is made”. See Seccombe v Attorney-General 1919 TPD 270, 272, 277‑278. This definition includes a photograph. See Mpumlo 1986 (3) SA 485 (E) which was agreed to by Baleka 1986 (4) 192 (T) 196H. • If it in fact contains written proof of facts, (in writing or ciphers), it is a document. See Seccombe v Attorney-General, suprap.277-278; • The ordinary meaning of the word ‘document’ is wide enough to include computer printouts. See Harper 1981 (1) SA 88 (D) 96C-F; De Villiers 1993 (1) SACR 574 (Nm) and Ndiki 2008 (2) SACR 252 (Ck). • It includes a “coin” according to Protea Assurance v Waverley Agencies 1994 (3) SA 247 (A) 249H-I.

  5. DOCUMENTS • COMPUTER PRINTOUTS CAN BE PROVED EITHER AS: • DOCUMENTARY EVIDENCE, OR AS • REAL EVIDENCE

  6. CLASSIFY THE TYPE OF PRINT-OUT ACCORDING TO THE FUNCTION OF THE COMPUTER • THE PURPOSE WITH THE CLASSIFICATION IS: • TO DISTINGUISH BETWEEN DOCUMENTARY EVIDENCE AND REAL EVIDENCE OF A DOCUMENTARY NATURE: • DOCUMENTARY EVIDENCE CAN BE HEARSAY EVIDENCE; • REAL EVIDENCE CANNOT BE HEARSAY EVIDENCE : • WHEN PRINTOUTS ARE DOCUMENTARY EVIDENCE, THE EVIDENTIAL WEIGHT OF THE EVIDENCE DEPENDS ON THE CREDIBILITY OF A PERSON. • WHEN PRINTOUTS ARE REAL EVIDENCE, THE EVIDENTIAL WEIGHT OF THE EVIDENCE DEPENDS ON THE “CREDIBILITY” OF THE ELECTRONIC SYSTEM BASED ON ITS HARDWARE AND SOFTWARE. • DIFFERENT LAW APPLIES RELATIVE TO THE ADMISSIBILITY OF DOCUMENTARY EVIDENCE ON THE ONE HAND AND REAL EVIDENCE ON THE OTHER.

  7. DOCUMENTS AND COMPUTER PRINTOUTS: • PRINCIPLES RELATIVE TO PROVING DOCUMENTARY EVIDENCE UNDER THE COMMON LAW: • PRIVATE DOCUMENTS: • ORIGINAL: VARIOUS; DUPLICATE ORIGINALS • AUTHENTIC: PURPORTS TO BE WHAT IT IS • TRUTH OF THE CONTENTS: VERACITY • PRINCIPLES RELATIVE TO PROVING REAL EVIDENCE OF A DOCUMENTARY NATURE UNDER THE COMMON LAW: • REAL EVIDENCE: • IDENTIFY / “AUTHENTIC” • RELIABILITY OF THE EQUIPMENT • NO NEED FOR THE ORIGINAL:MDLONGWA 2010 (2) SACR 419 (SCA) 427b – g; DE VILLIERS 1993 (1) SACR 574 (NM); • HNP v SEKRETARIS VAN BINNELANDSE SAKE 1979 (4) SA 274 (T)

  8. THE PURPOSE IS USUALLY TO PROVE THE TRUTH OF THE CONTENTS OF A PRINTOUT • DOCUMENTARY EVIDENCE: • THE AUTHOR • REAL EVIDENCE OF A DOCUMENTARY NATURE: • WE PROVE THE TRUTH OF THE CONTENTS VIA PROVING THE RELIABILITY AND CORRECT FUNCTIONING OF THE COMPUTER AND ITS SOFTWARE.

  9. RELIABILITY OF THE COMPUTER SYSTEM “THE RELIABILITY AND ACCURACY OF THE COMPUTER AND ITS OPERATING SYSTEMS ARE QUITE OBVIOUSLY RELEVANT FACTORS TO BE CONSIDERED IN THE EXERCISE OF THE COURT’S DISCRETION.” Ndiki 2008 (2) SACR 252 (Ck) 261d-h (par 54). REAL EVIDENCE: FUNCTIONAL RELIABILITY: COULD “BE SUPPLIED BY CIRCUMSTANTIAL EVIDENCE OF THE USUAL HABIT OR ROUTINE REGARDING THE USE OF THE COMPUTER.” THIS IS SOMETIMES REFERRED TO AS THE PRESUMPTION OF REGULARITY WHICH IS A COMMONSENSE INFERENCE, WHICH MAY BE DRAWN WHERE APPROPRIATE.

  10. KEEP THE FOLLOWING IN MIND WHEN INTENDING TO PROVE A COMPUTER PRINTOUT • Ndiki 2008 (2) SACR 252 (Ck) 261d-h: “It is not desirable to attempt to deal with computer printouts as documentary evidence simply by having regard to the general characteristics of a computer.” • DETERMINE: • The contents of the computer printout; • What it is that you wish to prove with the computer printout (which facts); • The function performed by the computer; and • The requirements of the relevant section relied upon for the admission of the computer printout/document in question. • THERE ARE THREE POSSIBLE CLASSIFICATIONS:

  11. THREE POSSIBILITIES: • WHERE THE INFORMATION IN THE PRINT-OUT CAME ABOUT AS A RESULT OF THE COMPUTER HAVING PROCESSED RAW DATA, WHICH DATA WAS ENTERED ONTO THE COMPUTER BY A PERSON? • THE COMPUTER WITH ITS SOFTWARE CALCULATES, SORTS, COLLATES AND SYNTHESISES THE ENTERED DATA. • THE COMPUTER THEN GIVES IT BACK IN A DIFFERENT FORMAT AS IT WAS ENTERED ONTO THE COMPUTER. • THIS IS REAL EVIDENCE. • THE EVIDENTIAL WEIGHT OF SUCH A PRINTOUT DEPENDS ON THE “CREDIBILITY” OF THE COMPUTER, SOFTWARE AND OPERATING SYSTEM.

  13. WHEN THE INFORMATION IN THE PRINT-OUT WAS ENTERED ONTO THE COMPUTER BY A PERSON IN CIRCUMSTANCES WHERE THE COMPUTER DID NOT PROCESS THE INFORMATION SO ENTERED? • A PERSON CREATED THE DATA ON THE COMPUTER. • THE COMPUTER THEN GIVES IT BACK IN THE SAME FORMAT AS IT WAS ENTERED ONTO THE COMPUTER. • THIS IS DOCUMENTARY EVIDENCE.

  14. aaaaaaaaaaaaaaaaa Aaaaaaaaaaaaaaaaaaaa Aaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaa Aaaaaaaaaaaaaaaaaaaa Aaaaaaaaaaaaaaaaaaaa

  15. WHEN THE INFORMATION WAS RECORDED BY MECHANICAL MEANS WITHOUT THE PERSONAL INVOLVEMENT OF A HUMAN BEING? • A PERSON ONLY ACTIVATE THE ELECTRONIC SYSTEM. • THE SYSTEM THEN GENERATES INFORMATION BASED ON ITS SOFTWARE • THE SYSTEM MAINLY RECORDS AND STORES. • THIS IS REAL EVIDENCE. • A COURT MAY TAKE JUDICIAL NOTICE OF THE GENERAL RELIABILITY OF THE TYPE OF EQUIPMENT THAT WAS USED: • Inference reliability relative to the specific equipment that was used • WHEN A COURT CANNOT TAKE JUDICIAL NOTICE OF THE GENERAL RELIABILITY OF THE EQUIPMENT: • Viva voce evidence relative to the general reliability: • Inference of reliability relative to the specific equipment that was used. • Direct Viva voce evidence of reliability relative to specific equipment. • (Equipment that must be tested or calibrated)

  17. CLASSIFICATION 1 AND 3: • REAL EVIDENCE: • PROOF OF THE TRUTH OF THE CONTENTS

  18. THE FOLLOWING DO NOT BELONG TO CLASSIFICATION 3:NOT PROOF OF THE TRUTH OF THE CONTENTS • E-MAILS • SMS’S • SCANNED DOCUMENTS • FACSIMILES • ONLY PROOF OF THE CONTENT THAT WAS ENTERED ONTO THE EQUIPMENT; • WHAT STANDS TO BE PROVED WILL DETERMINE WHETHER IT IS • REAL EVIDENCEOR • DOCUMENTARY EVIDENCE

  19. EVIDENCE EMANATING FROM ELECTRONIC EQUIPMENT (ALL THREE CLASSIFICATIONS), AND • VIDEOS, AUDIOS, RECORDINGS FROM SURVEILLANCE EQUIPMENT AND THE LIKE, CAN BE ADMITTED UNDER THE ELECTRONIC COMMUNICATIONS ACT 25 OF 2002.

  20. 1ST CLASSIFICATION (REAL EVIDENCE)

  21. THE COURTS ALREADY IDENTIFIED REAL EVIDENCE OF A DOCUMENTARY NATURE IN 1976, WITHOUT REFERRING TO IT AS SUCH. • THIS IS THE CASE WHERE THE PRINTOUT CAME ABOUT BY THE COMPUTATION, SORTING, COLLATING AND SYNTHESISING OF DATA BY THE COMPUTER AND NOT BY A PERSON.

  25. SECTION 15 OF THE ECT ACT Admissibility and evidential weight of data messages 15. (1) In any legal proceedings, the rules of evidence must not be applied so as to deny the admissibility of a data message, in evidence - (a) on the mere grounds that it is constituted by 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 in the form of a data message must be given due evidential weight. (3) In assessing the evidential weight of a data message, regard must be had to - (a) the reliability of the manner in which the data message was generated, stored or communicated; (b) the reliability of the manner in which the integrity of the data message was maintained; (c) the manner in which its originator was identified; and (d) any other relevant factor. (4)A data message made by a person in the ordinary course of business, or a copy or printout of or an extract from such data message certified to be correct by an officer in the service of such person, is on its mere production in any civil, criminal, administrative or disciplinary proceedings under any law, the rules of a self regulatory organisation or any other law or the common law, admissible in evidence against any person and rebuttable proof of the facts contained in such record, copy, printout or extract.

See 96C-F; • Ningise: Applied the extended definition of ‘document’ to admit a printout where the device which printed the cell phone records, only records and stores (classification 3) the information, where interconnectivity is in issue.
