John Sopinka 1933-1997 To the memory of our colleague and friend, John Sopinka, who embodied excellence in the law as a judge, counsel, teacher and scholar. PREFACE The “Principled Approach” and “Charter Values”, adopted by the Supreme Court of Canada, have infused virtually every facet of Evidence Law, as we continue to move away from a Rules-based system to one that is rooted in principle. The word “Rules” itself connotes strict adherence and arbitrary application. In many circumstances, such slavish following of Rules has led to the exclusion of much reliable evidence and, conversely, the admission of unreliable and prejudicial evidence. This has resulted in injustices, wrongful convictions and unjust acquittals alike. A better understanding and proper application of principles should do much to avoid such consequences. This edition of The Law of Evidence in Canada tracks these developments and, we hope, contributes to a greater appreciation of these principles. We extend our thanks once again to Lee Seshagiri for his re-working of Chapter 18: Documentary Evidence, to take into account the prevalent use of electronic information and social network evidence. Helen Incognito’s clerical assistance in the preparation of text and footnote revision for some of the chapters is acknowledged and appreciated. Finally, we are most grateful for the efforts of Sheila Nemet-Brown of LexisNexis in updating several chapters and, in her tactful way, keeping us on course for a timely completion of this edition.
