In 1865, the British Colony of Hong Kong extradited a Chinese shop-owner on a charge of piracy and incited a barrage of criticism when the offender was punished by the infamous “death by a thousand cuts” in Canton upon his rendition. Rumors surfaced identifying him as a rebel chief in the Taiping Rebellion (1850–1864). By excavating court records, diplomatic exchanges, and legal discourses surrounding this case, the article engages in a critical examination of extradition law and implementation in mid-19th century between Hong Kong and China. It examines how the case played into the politics of four administrative localities - Hong Kong, Canton, Beijing, and London - and uncovers the networks of agencies at play. It contributes to the history of extradition by contextualizing the “political offence exception” in international law and explains how this exception, ill-defined and vaguely conceived as it was, found its way into the implementation of Article 21 of the Treaty of Tianjin on the rendition of fugitives from Hong Kong to China, with a significant impact on the Qing's governance and jurisdiction of cross-border fugitives.
