The binding legal principles established are: (1) Computer-generated documents, including emails, are subject to the requirements of section 13 of the Civil Evidence Act, but these requirements should be applied pragmatically given that most documentary evidence is now computer-generated; (2) A party's failure to properly traverse the prerequisites for admitting computer-generated documents does not automatically result in exclusion if the deficiency can be remedied through procedures available under the Civil Evidence Act; (3) Courts have discretion under section 50 of the Civil Evidence Act to examine evidence and hear submissions to determine admissibility, even where initial procedural deficiencies exist; (4) Litigation is a serious legal process regulated by statute, not a 'game of wits', and courts should adopt a substantive rather than overly technical approach to evidential objections where justice requires; (5) Electronic evidence requires authentication, but concerns about authenticity can be addressed through various pre-admission facilities in the Civil Evidence Act including section 19, rather than automatic exclusion.
