This book honours a remarkable legal thinker, David Feldman, whose influence on public law and on multiple generations of legal scholars and practitioners has been profound.It provides a unique set of insights into some of the most topical and enduring questions in public law (broadly conceived), through the reflections of a stellar line-up of contributors on key dimensions of David Feldman’s rich body of work.Each chapter constitutes an original and important contribution to the field, taking David Feldman’s seminal writings as a starting-point and developing contemporary, distinctive analytical perspectives.Like David Feldman’s work itself, the book ranges across — and acknowledges and explores the porous relationships between — constitutional law, administrative law and human rights and civil liberties.
