STEPHEN GUEST writes mostly on legal and political philosophy, particularly concerning the question of justification in legal reasoning and the relationship between justice, interpretation and laws. His well-known book Ronald Dworkin appeared in its second edition in 1997. Amongst other work, he has published in Public Law on constitutional problems of legal revolution, the Law Quarterly Review on hearsay evidence, the Journal of Medical Ethics on the rights of the subjects of medical research, Acta Juridica on the role of equality within legal reasoning, and Revue Internationale de Philosophie on the idea that law is a form of justice (to which Dworkin published a reply). He has recently published essays on objectivity in value and the fallibility of judges, the implication of Dworkin's legal and political theory for political stability, and on his father's experience as a POW lecturing on the University of London international programme in Stalag IVB in Muhlberg, Germany, and Campo 52 in Chiavari, Italy. His most recent publications are on how to criticise Dworkin's legal theory in Analysis 2009, and on the promulgation of the criminal law on Pitcairn Island for the New Zealand Law Journal in 2010. He recently gave a public lecture at UCL on the Right to Obscene Thoughts for which he was nominated as Academic of the Year 2010 by the Erotic Awards.
