This collection of essays explores the two libel cases (criminal and civil) prosecuted by Rev. Samuel Marsden against John Thomas Campbell in 1817, following the publication of the Philo Free letter. The event is examined in the various contexts of Imperial and Australasian Colonial History, Marsden historiography and biography, Australian legal history, South Seas missions history, the history of Australian indigenous missions, the freedom of the press, and normative ethics.
