Law of Forensic Science by Dr. Ishita Chatterjee, published by Central Law Publications, is a textbook written for law students and lawyers rather than for laboratory scientists. Second Edition, 2023, 490 pages.

Forensic science reaches the courtroom as evidence, and evidence is governed by law. That is the premise of this book and what separates it from a criminalistics manual. A lawyer does not need to be able to run a gas chromatograph; a lawyer needs to know what weight a medical opinion carries, when an expert's evidence can be acted upon without corroboration, what the court may do when the medical and ocular accounts conflict, and how a DNA report is proved. The treatment here is accordingly legal throughout, with the underlying science explained only as far as a non-scientist needs it to follow the argument.

This edition is written against the law of evidence as it now stands and covers the expert-evidence provisions, the proof of scientific reports and the questions of consent and personal liberty that arise when a court directs a medical or scientific examination. Dr. Ishita Chatterjee's title has been a standard reading on the Forensic Science and Medical Jurisprudence papers offered at Indian law schools since the first edition.

Why Choose This Book?

Most books on this subject come from one of two directions. Forensic science textbooks are written by scientists and treat the law as a footnote; medical jurisprudence treatises are written for doctors and assume a clinical background. A law student sitting a Forensic Science paper, or an advocate preparing to cross-examine a medical officer, needs neither of those. They need the subject organised the way the courtroom organises it — around what can be proved, by whom, and with what weight. That is how this book is built.

Its other merit is proportion. At 490 pages in a single paperback it is a book that can actually be read through in a semester and carried to court, and it is priced as a student text. For the money it covers a remarkable range: the classical medico-legal ground of injuries, death and post-mortem, and then forward into DNA legislation, narco-analysis and the self-incrimination question, medical negligence before the Consumer Commissions, mental health law and neuroscience. That breadth is what makes it serve both as a course book and as a first reference in practice.
