In recent years, it has become increasingly clear that there are important connections relating three concepts -- groupoids, inverse semigroups, and operator algebras. There has been a great deal of progress in this area over the last two decades, and this book gives a careful, up-to-date and reasonably extensive account of the subject matter. After an introductory first chapter, the second chapter presents a self-contained account of inverse semigroups, locally compact and r-discrete groupoids, and Lie groupoids. The section on Lie groupoids in chapter 2 contains a detailed discussion of groupoids particularly important in noncommutative geometry, including the holonomy groupoids of a foliated manifold and the tangent groupoid of a manifold. The representation theories of locally compact and r-discrete groupoids are developed in the third chapter, and it is shown that the C*-algebras of r-discrete groupoids are the covariance C*-algebras for inverse semigroup actions on locally compact Hausdorff spaces. A final chapter associates a universal r-discrete groupoid with any inverse semigroup. Six subsequent appendices treat topics related to those covered in the text. The book should appeal to a wide variety of professional mathematicians and graduate students in fields such as operator algebras, analysis on groupoids, semigroup theory, and noncommutative geometry. It will also be of interest to mathematicians interested in tilings and theoretical physicists whose focus is modeling quasicrystals with tilings. An effort has been made to make the book lucid and 'user friendly"; thus it should be accessible to any reader with a basic background in measure theory and functional analysis.

Winner of the Inner Temple book prize 2015 and the Socio-Legal Studies Association Book prize 2014/15 The House of Lords, for over 300 years the UK's highest court, was transformed in 2009 into the UK Supreme Court. This book provides a compelling and unrivalled view into the workings of the Court during its final decade, and into the formative years of the Supreme Court. Drawing on over 100 interviews, including more than 40 with Law Lords and Justices, and uniquely, some of their judicial notebooks, this is a landmark study of appellate judging 'from the inside' by an author whose earlier work on the House of Lords has provided a scholarly benchmark for over 30 years. The book demonstrates that appellate decision-making in the UK's final court remains a social and collective process, primarily because of the dialogues which take place between the judges and the key groups with which they interact when reaching their decisions. As the book shows, the forms of dialogue are now more varied, yet the most significant dialogues continue to be with their fellow Law Lords and Justices, and with counsel. To these, new dialogues have been added, namely those with foreign courts (especially Strasbourg) and with judicial assistants, which have subtly altered the tenor and import of their other dialogues. The research reveals that, unlike the English Court of Appeal, the House of Lords in its last decade was only intermittently collegial since Lord Bingham's philosophy of appellate judging left opinion writing, concurrences and dissents largely to individual preference. In the Supreme Court, however, there has been a marked shift to team working and collective decision-making bringing with it challenges and occasional tensions not seen in the final years of the House of Lords. The work shows that effectiveness in group-decision making in the final court turns in part on the stages when dialogues occur, in part on the geography of the court and in part on the task leadership and social leadership skills of the judges involved in particular cases. The passing of the Human Rights Act and the expansion in judicial review over the last 30 years have dramatically altered the two remaining dialogues - those with Parliament and with the Executive. With the former, the dialogue has grown more distant, with the latter, more problematic, than was the case 40 years ago. The last chapter rehearses where the changing dialogues have left the UK's final court. Ironically, despite the oft applauded commitment of the new Court to public visibility, the book concludes that even greater transparency in the dialogue with the public may be required. 'The way appellate judges at the highest level behave to each other, to counsel, with other branches of government and with other courts is brought under closer scrutiny in this book than ever before…The remarkable width and depth of his examination…has resulted in a work of real scholarship, which all those who are interested in how appellate courts work all over the common law world will find especially valuable.' From the foreword by Lord Hope of Craighead KT 'Alan Paterson's knowledge and interest in the Supreme Court, coupled with his expertise as a lawyer who understands the legal system and the judicial process, make him a perfect chronicler and assessor of what the Court's role is and what it should be, and how it functions and how it might improve.' Lord Neuberger, President of the Supreme Court

he publication in 1999 of Paths to Justice presented the results of the most wide-ranging survey of public use of and attitudes towards the civil justice system ever conducted in England and Wales by either an independent body or government agency. Paths to Justice in Scotland replicates that survey, focusing upon the experiences of ordinary citizens in Scotland as they grapple with the kinds of problems that could ultimately end in the civil courts. In an era of almost unprecedented interest in the resolution of civil disputes and in the procedures and public funding available to assist in the process there remains a lacuna in terms of knowledge of public use of the civil justice system in Scotland which this major survey sets out to fill. In it, the authors identify how often people experience problems for which there might be a legal solution and how they set about solving them. Revealing crucial differences in the approach taken to different kinds of potential legal problems, the study describes the factors that influence decisions about whether and where to seek advice about problems, and whether and when to go to law. In addition to exploring experiences of courts, tribunals and ADR processes, the study also provides important insights into public confidence in the courts and the judiciary in Scotland. For the first time the study reveals the public's perspective on access to civil justice and makes a significant contribution to debate concerning public experience, expectations and needs when trying to resolve justiciable problems.

Publicly funded legal aid has undergone rapid change in this century. Developing from charity to large scale, publicly funded schemes, legal aid flourished in many western countries in the 1960s and 1970s. But, during the 1980s governments began to lose faith in publicly funded legal aid. In the 1990s major funding and eligibility cuts have occurred in Sweden, England and Wales, the USA, Canada, Australia and the Netherlands. To answer the need for a better understanding of the extraordinary rise and fall of legal aid, this book brings together contributions from the leading international scholars in the field. Researchers from north America, Europe and Australia examine the origins of modern legal aid, analyse its recent rapid decline and consider its likely future. This collection of original studies does not, however, merely describe legal aids changing fortunes. The contributors also apply legal and social science perspectives to analyse and theorise about legal aid. In particular, rather than describe developments in individual societies, the contributors compare legal aid across societies to develop important insights including legal aids relationship with the legal profession, welfare states and legal families. This book will be embraced by all those interested in legal aid.

For the 2010 Hamlyn Lectures, Alan Paterson explores different facets of three key institutions in a democracy: lawyers, access to justice and the judiciary. In the case of lawyers he asks whether professionalism is now in terminal decline. To examine access to justice, he discusses past and present crises in legal aid and potential endgames, and in relation to judges he examines possible mechanisms for enhancing judicial accountability. In demonstrating that the benign paternalism of lawyers in determining the public good with respect to such issues is no longer unchallenged, he argues that the future roles of lawyers, access to justice and the judiciary will only emerge from dialogues with other stakeholders claiming to speak for the public interest.
