The primary purpose of this paper is to indicate how Canadian legislative reforms could provide valuable insights regarding the reform of sexual assault law in South Africa. The first section of this paper contains an examination of three particular evidentiary rules in the South African context. In the second section a feminist critique of rape law is used to explore the significance of these rules in rape trials, using the framework of significant themes of the feminist enquiry. In the third section I look at the development of these evidentiary rules in Canada and evaluate the present legal position in this regard, with particular reference to decision of the Supreme Court of Canada in R v Seaboyer, R v Gayme (1991) 83 D.L.R. (4th) 193. In the final instance, an attempt is made to identify some significant lessons for those seeking to formulate the much needed reforms to these rules in South Africa.

The acquisition of digital evidence is the most crucial part of the entire digital forensics process. During this process, digital evidence is acquired in a forensically sound manner to ensure the legal admissibility and reliability of that evidence in court. In the acquisition process various hardware or software tools are used to acquire the digital evidence. All of the digital forensic standards relating to the acquisition of digital evidence require that the hardware and software tools used in the acquisition process are validated as functioning correctly and reliably, as this lends credibility to the evidence in court. In fact the Electronic Communications and Transactions Act 25 of 2002 in South Africa specifically requires courts to consider issues such as reliability and the manner in which the integrity of digital evidence is ensured when assessing the evidential weight of digital evidence. Previous research into quality assurance in the practice of digital forensics in South Africa identified that in general, tool validation was not performed, and as such a hypothesis was proposed that digital forensic practitioners in South Africa make use of hardware and/or software tools for the forensic acquisition of digital evidence, whose validity and/or reliability cannot be objectively proven. As such the reliability of any digital evidence preserved using those tools is potentially unreliable. This hypothesis was tested in the research through the use of a survey of digital forensic practitioners in South Africa. The research established that the majority of digital forensic practitioners do not use tools in the forensic acquisition of digital evidence that can be proven to be validated and/or reliable. While just under a fifth of digital forensic practitioners can provide some proof of validation and/or reliability, the proof of validation does not meet formal international standards. In essence this means that digital evidence, which is preserved through the use of specific hardware and/or software tools for subsequent presentation and reliance upon as evidence in a court of law, is preserved by tools where the objective and scientific validity thereof has not been determined. Since South African courts must consider reliability in terms of Section 15(3) of the Electronic Communications and Transactions Act 25 of 2002 in assessing the weight of digital evidence, this is undermined through the current state of practice in South Africa by digital forensic practitioners.

This study has a twofold purpose in that it attempts to identify how knowledgeable investigators are about the collection and use of DNA in relation to the building of a criminal case, and to establish how optimally DNA as evidence is utilised. The study has revealed several shortcomings which render the use of DNA evidence inadmissible in criminal proceedings. The researcher also analysed other aspects relating to DNA evidence, namely: identification, individualisation, criminal investigation, forensic investigation, and objectives of criminal investigation. For criminal investigators to be successful in their investigation of cases involving DNA, it is imperative for them to have a clear understanding of the basic concepts surrounding DNA investigations and the value of DNA evidence. It is submitted that, because of a lack of knowledge in DNA-related investigations by detectives, a lack of training in DNA-related cases and delays in the collection of DNA evidence, valuable evidence is often lost and/or contaminated. This causes such evidence to become inadmissible in criminal proceedings, and has a negative impact on the conviction rate for such crimes. / Preface in English and Afrikaans / Hierdie studie het ’n tweevoudige doel in die poging om te identifiseer hoe kundig ondersoekers is aangaande die insameling en gebruik van DNA in terme van die bou van ’n kriminele saak en die vasstel van hoe DNA optimal [sic] as bewys gebruik kan word. Die studie het getoon dat daar verskeie tekortkominge is wat teweeg gebring het dat die gebruik van DNA bewys onaanvaarbaar was in kriminele prosedure. Die navorser het ook ander aspekte geanaliseer aangaande DNA bewyse, naamlik: identifikasie, individualisering van onderwerpe tydens ondersoek, kriminele ondersoek, forensiese ondersoek, en die aspekte van kri-minele ondersoeke. Vir die kriminele ondersoekers om suksesvol te wees in hulle ondersoek van sake waarby DNA betrokke is, is dit vir hulle van kardinale belang om ’n suiwere begrip van die basiese konsep rondom DNA ondersoeke en die waarde van DNA bewyse te hê. Dit is voortgebring dat, as gevolg van die tekort aan kennis in DNA ondersoeke, asook opleiding van DNA-sake by die speurders, en vertraging in die versameling van DNA bewysstukke, waardevolle bewyse is telkens verlore of gekontamineer. Dit veroorsaak dat sulke bewyse verwerp word in kriminele prosesse, en het ’n negatiewe impak op die vonnis statestieke [sic] vir sulke misdade. / Criminology / M.Tech. (Forensic Investigation)
