Ashworth's Principles of Criminal Law is a textbook on criminal law in England and Wales. The principles of criminal law expounded in the book are normative. [1]
The text was originally written by Professor Andrew Ashworth (first to sixth editions: 1991–2009). The seventh edition (2013) was co-written with Professor Jeremy Horder and the eighth to tenth (2016, 2016, 2022) editions were written by Horder alone.
Anthony Duff called the book valuable. [2]
