The present sixth edition on the subject by Prof. S.C. Shastri has been thoroughly revised and updated with statutory and case law developments. The author has discussed the distinctive shift in the approach of the courts to achieve the goal of environmental justice i.e. from anthropocentric approach to eco-centric approach. The focus of the court has shifted from humans to the protection and preservation of ecology or the present species of flora and fauna. The evolving concept of “corporate social responsibility” in relation to environmental justice has also been provided due place in the book. The book will be useful to students of LL.B. and LL.M., researchers, administrators, academicians, judges, advocates and NGOs.
