This expanded new edition of Law in Perspective focuses on a range of powerful critical thinking tools drawn from logic, science, ethics, and political and social theory. Information on terrorism and refugee law has been fully updated, climate change is discussed throughout, and new chapters have been added on law and Indigenous people, lawyers’ ethics and corporate power. The book considers the relationship between legal theory, social theory and empirical research methods, as a guide for students taking on higher degrees in legal research. It also analyses key theories of the nature and social role of law, including legal positivism, natural law theory and Marxist theory of law.
