Lysander Spooner's 'An Essay on the Trial By Jury' is a groundbreaking work that argues for the right of juries to determine not only the guilt of the accused but also the justice of the laws under which they are tried. In this volume, Spooner provides a comprehensive view of the English constitution, exposes the unconstitutional means by which trial by jury has been undermined, and shows that juries, in both England and the United States, are constitutionally empowered to make decisions based on Common Law principles. He explores the history, language, and moral considerations behind the Magna Carta, which enshrined the right to trial by jury. This book is an essential read for anyone interested in the fundamental principles of justice and the role of juries in upholding them.
