1 This article is based in part upon a contribution by the author to a discussion on “Recent Developments in the Law of Extradition and Deportation” at a conference held under the auspices of the British Institute of International and Comparative Law at Leeds University, March 6, 1965. The author wishes to acknowledge the debt he owes to Mr. J. B. Macartney, of Queen's University, Belfast, who drew his attention to a number of recent Irish cases. He is very much indebted also to Mr. Peter Gail, who, being the object of an application for extradition from the Republic to the U.K., has pointed out a number of problems to the author.
