Book excerpt: Welsh Planning Law and Practice provides a comprehensive guide to the sources and structure of Welsh planning law and a route through its complexity. This is not a comparative study, but rather deals with legislation and policy affecting land in Wales, placing them in the context of shared principles and concepts and the case law common to England and Wales. More than an academic exercise, planning is a practical matter affecting important aspects of daily life, and the desirability of public engagement in the planning process is well settled. This book contributes to the promotion of recognition of the body of Welsh planning law, to aid accessibility for all who practise in or who are (or want to be) involved in shaping development in Wales.
