This book is concerned with the organisation, powers and accountability of
government in the British constitution. It has been written from a lawyer™s per-
spective, modi¬ed by an awareness that the British constitution is far from
being exclusively the handiwork of lawyers. Judges and other practitioners of
the discipline of law have made a notable contribution to it, but so have politi-
cal philosophers, controversialists of many hues, party organisations, peers,
rebels in and out of Parliament and the legions of special interests. Yet lawyers
sometimes pretend that the constitution is theirs, teaching and writing about it
in myopic isolation.
We have written this book in the conviction that the law student will arrive
at an incomplete and fragmentary view of the constitution unless encouraged
to take account of ideas, practices and relationships that occur outside the strict
limits of the law of the constitution. The law student has much to learn from
writers and practitioners in politics, government and public administration,
just as students of these subjects can enrich their studies by learning something
of the values, constraints and possibilities of the law. If asked a question, say,
about the power of Parliament, a lawyer and a political scientist may give very
di¬erent answers. But they are describing the same institution, and for a full
understanding of its place in the constitution each of them needs to take the
other™s perspective into account.
We have set out in this book to present essential features of British govern-
ment and the constitution in a way that o¬ers a wider range of views to students
of law and we hope also to students of politics and government. The materials
in the book are taken not only from law reports, statutes and legal works but
from a variety of o¬cial and uno¬cial publications and from the writings of
political scientists, parliamentarians and other commentators on the constitu-
tion and the practice of government. We have tried in this way to show the
variegated texture of a constitution which consists not only of rules “ legal,
quasi-legal and customary or conventional “ but of ideas, habits of mind and
shared understandings: a constitution continually reshaped in the daily practice
of politics and administration as well as by the deliberate law-making of
legislators and judges.
The student of the British constitution soon ¬nds that there are present in it

two opposite principles: a principle of change and a principle of continuity.
Until quite recent times, studies of the constitution generally over-emphasised
the latter principle, presenting the constitution as something stately and settled,
secure in its foundations, strong in its continuity and consistent in its slow
evolution. By contrast, a good deal of the more recent literature focuses overly
on the changing constitution at the expense of the continuing, the historical and
the traditional. For all the reform we have seen to the British constitution in the
last thirty years or so, there is much that remains of the old order (see further
chapter 1). The ˜venerable constitution™ is still, in all sorts of respects, an apt
description. What is needed “ and what we hope we have provided here “ is a
balanced account that addresses both the elements of change and continuity
that we ¬nd at the heart of the British constitution today.
The ¬rst ¬ve editions of this book were written by Colin Turpin. This is the
¬rst edition to have been jointly prepared by Colin Turpin and Adam Tomkins.
We have both worked on each of the chapters and take joint responsibility for
them all. Readers of earlier editions will ¬nd much that is familiar here but, for
this edition, the book has been extensively revised and reworked, as well as
updated. Some chapters are new to this edition, others have been substantially
restructured, and the order in which the chapters appear has been altered to
make clearer sense, we hope, of today™s constitutional law and practice. The
book is divided into four parts. Part I (chapters 1“5) deals with the fundamen-
tal ideas that govern the constitution (democracy, sovereignty, the rule of law
and so forth) and with the multiplicity of sources, both domestic and European,
that now contribute to it. In this Part, too, readers will ¬nd consideration of
constitutional reform and of the structures of devolution that have transformed
British government, at least in some parts of the United Kingdom, since 1998.
Part II (chapters 6“7) is concerned with central government, with its institu-
tions, personnel and powers. Part III (chapters 8“10) focuses on the various
ways in which British government is subject to forms of accountability. In this
Part we consider, in turn, the relative roles of the people, of Parliament and of
the courts of law in this regard. When we come to the courts (in chapter 10)
both the law of judicial review and the principles of liability are discussed.
Part IV (chapter 11) considers the extent to which, and the means by which, the
British constitution seeks to secure a degree of personal liberty. This is an
element of the constitution that has been sorely tested in recent years in the face
of a series of apparent threats to national and international security. We con-
sider in some detail the ways in which British constitutional law has responded
to this challenge.
Colin Turpin gives especial thanks to Monique for her constant encourage-
ment and practical help with work on the book. Once again he is grateful to the
Master and Fellows of Clare College for collective, friendly stimulus and to
the students whose enthusiasm, alertness and scepticism make the whole enter-
prise of teaching and writing about law exciting and worthwhile.
Adam Tomkins thanks his colleagues Gavin Anderson, Aileen McHarg and
