The third edition has been written to respond to those significant changes in Irish law since 1996. Its main aim is to provide students with a broad knowledge of the principles of Irish law as it affects commercial transactions, and to increae their awareness of the need to consider the legal implications in the decision-making process. Like its predecessors, this book is designed primarily for students sitting examinations in third-level colleges and professional institutes, but it is also relevant to students taking an intriductory law course.
