This chapter examines the marginal notes added to the key British dossiers relating to the Sung Man Cho v. Superintendent of Prisons case, revealing a picture of perplexity and even confusion as to the way ahead in ongoing correspondence between the British Foreign Office, the Colonial Office, the Secretary of State for the Colonies, the Home Office and other concerned departments. In the background, especially as interpreted by Crown Council F. C. Jenkin QC, stood a complex British legal discourse on banishment/deportation and extradition.
