The legislative process is complex, encompassing a variety of aims and outcomes. Some norms and rules are embodied in law because we are simply expected by government to follow them. Others are there for entirely different reasons. A legislator may wish to send messages about what constitutes desirable behaviour, to demonstrate government's ability to deal with a local and short-term issue or to distract the electorate from other crises. Law is often, though not always, designed as a means to an end. Taking a sociological and empirically-based approach, this book offers a rare insight into the real processes by which lawmakers attempt to influence (or fail to influence) human behaviour.

This account of the legislative process in Westminster rests on the author's observations and discussion with key players from the standpoint of an academic adviser on research to the department responsible for family law-making (originally the Lord Chancellor's department, then the Department for Constitutional Affairs and now the Ministry of Justice) and draws on her longstanding involvement in and knowledge of the processes of law-making. Documenting the little understood processes that occur in Whitehall, in particular how ministers, advisers and officials work together, it reveals a quite different picture from that of the rational lawmaker imagined in textbooks. Instead what emerges is an empirically-based view of the aims and functions of statute law including the different forms and relevance of symbolic legislation and a realistic view of what law aims to accomplish and what can be done in practice.
