This book is intended to facilitate a better understanding of the principles of criminal procedure and its applications in a court of law, by providing highlights of the leading judicial pronouncements of the Malaysia courts. It is with this thought in mind that the authors crafted the book in such a way as to not only list out the general principles of law relating to the major issued in each relevant area of criminal procedure, but also to reproduce the instructive portions of the judgments. Each chapter begins with commentary on the areas concerned, followed by summary of general or specific principles of law as decided by courts of the highest hierarchy available. Leading decisions and an extract of its most relevant part of the judgements are then reproduced. T is hoped that this book serves as an indispensable source for law students and criminal practitioners at all levels in the understanding and appreciation of the law relating to pre-trial procedures and jurisdiction of criminal courts in Malaysia.
