This work investigates the historical development and socio-political implications of the English system where police, rather than public prosecutors, held the authority to prosecute the accused between 1750 and 1850. Douglas Hay and Francis Snyder, both established scholars in legal history, utilize archival records and constitutional theory to analyze how this unique prosecutorial framework functioned within the broader context of state power and class relations. They argue that the evolution of these practices was deeply intertwined with the social structures of the era, providing a critical look at the transition toward the modern Crown Prosecution Service.
