This article examines the criminal law reform career of James Mackintosh (1765–1832). As Recorder of Bombay (1804–11), writer and Whig MP (1813–32), Mackintosh engaged with diverse aspects of criminal law. His view of the organic relationship between law, society, and public opinion, which was shaped by his Scottish intellectual background and Foxite Whig politics, was distinct from the radical and liberal political perspectives most often associated with criminal law reform. The article traces the implications of Mackintosh's approach for the practice of politics and legislation in the period and suggests cause to revise assessments of its outcomes.
