Great Debates in Law is an evolving series offering engaging and thoughtful introductions to the more advanced concepts, written by authors who are amongst the foremost thinkers in their field. They are designed to provide a cutting edge for students who are looking to gain additional insights with which to excel. The series looks to go beyond what is covered in the main textbooks, presenting the key tensions and questions underlying a subject, setting legal developments in their philosophical and cultural context and exploring the issues as matters of current debate. The text draws upon the work of leading figures to elucidate the concepts addressed, illustrating how a subject has developed in the way that it has, and why.
