He received the prestigious Baron Dr. Ver Heyden De Lancey Prize for the best performance by a Middle Temple member in the Bar Examinations. Before he joined the academic community, Luke was an Erasmus Scholar, receiving a grant to work at the United Nations International Criminal Tribunal for the Former Yugoslavia. Whilst there he was legal assistant to trial attorneys tasked with the indictment of Bosnian Genocide suspect, Radovan Karadzic. He has taken on cases for Justice Centre Hong Kong (formerly Hong Kong Refugee Advice Centre) providing legal representation to asylum seekers appearing before the UNHCR. His most recent scholarly work includes a detailed examination of the erosion of the adversarial process in the English criminal justice system. Luke was selected for the Faculty’s inaugural Research in Teaching & Learning Award, in recognition of his research on the advancement of the teaching and learning experience.

Books / Monographs

Mirjan Damaška (Sterling Professor Emeritus of Law, Yale Law School): “The full adjudicative process is everywhere in decline, replaced by various forms of negotiated or bargained justice. Langer, McConville and Marsh subject these new forms of justice to theoretical analysis from a variety of perspectives and offer thoughtful reflections about their likely future.”

Stephen J. Schulhofer (Robert B. McKay Professor of Law Emeritus, New York University School of Law): An extraordinarily ambitious project … which offers incisive normative critique and perceptive guidance for future research. An invaluable contribution.

Jill Hunter (Professor of Law, UNSW Law & Justice): a milestone in contemporary criminal justice scholarship … [i]t cuts across legal traditions addressing corporate offender deal-making, empirical studies, ethical failures, myth, inequality, gender and race, revealing the global spread of failed justice through coercive incentives to concede guilt…”

Fiona Leverick (Professor of Criminal Law and Criminal Justice, University of Glasgow): “…timely, comprehensive and innovative … [a] real “must-read” for anyone interested in the contemporary debates about plea bargaining.”

Andrew Manuel Crespo (Morris Wasserstein Public Interest Professor of Law, Harvard Law School): “Brimming with comparative insights, the international experts here offer a cautionary chorus, warning the world of an epidemic of plea bargaining now spreading across the globe.”

Robert Blackburn QC (Professor of Constitutional Law, King’s College London):

The leading study of judicial independence, superbly researched and fascinating reading for everyone interested in the past and present workings of the legal and justice system within the structure of British government … an indispensible and outstanding work.”

Richard Abel (Michael J. Connell Distinguished Professor of Law Emeritus, UCLA):

It will force a fundamental reconsideration of the ‘Westminster Model’ at the very moment when it is under enormous stress.

Geoffrey Robertson QC (Doughty Street, London):

This book offers a fascinating analysis of behind-the-scenes interplay between English judges, politicians, Whitehall and the police over the non-statutory rules which throughout the twentieth century were meant to secure the liberty of the subject from oppressive police action.”

Paul Roberts (Professor of Criminal Jurisprudence, Nottingham):

In a narrative by turns gripping and disturbing… [t]his ‘history of the present’ poses urgent questions for the contemporary condition of the administration of criminal justice, the vitality of common law method and the (global) rule of law under the tightening rachets of managerialism and austerity.”

  • Criminal Judges: Legitimacy, Courts and State-Induced Guilty Pleas in Britain (Edward Elgar, June 2014) (120,000 words) (with M McConville)
    Against a backdrop of a dysfunctional criminal justice system, this monograph on criminal justice brings legal and empirical material to question the legitimacy of the relationship between judges, lawyers, politicians and defendants in modern Britain. Examining existing legal structures and court practices through the lens of what used to be called ‘plea bargaining’ the book provides a graphic picture of why case disposals through enforced guilty pleas promote injustice, feed discrimination and skew the judicial function. This is the most comprehensive examination to date of case disposition methods in England, Wales and Scotland, underpinned by a new socio-legal theory on the criminal process.
