“There are a couple of wonderful things about this book. One is certainly the clearness of language and the general accessibility of her work. Another is her explicit focus on the technical aspect of the law, i.e., on the law as a specific social technique. This presents a welcome shift from a rather unfruitful focus on the law's essence to its functioning (note, not its function!), i.e., from what the law is to how exactly the law does what it does.” – Christoph Kletzer, Reader in Law, Kings College London,

“Köpcke's insightful, thorough, elegantly written, and rigorous treatment of legal validity deserves a careful reading. Indeed, it is my belief that anyone interested in fundamental legal questions will find Legal Validity: The Fabric of Justice a stimulating, instructive, and refreshing work.” – Stefano Bertea, School of Law, University of Leicester,
