LONDON — Politicians in Britain and in Japan often talk glibly about the importance of the rule of law. But how many of them have a clear idea of what this important phrase means?

A book by Tom Bingham titled "The Rule of Law" was recently published in Britain. It ought to be on the bedside table of every politician and will, I hope, be translated into Japanese.

Bingham was lord chief justice of England and senior law lord. He has thus filled the highest judicial appointments in Britain and is highly respected for his legal knowledge and integrity. His book is based on his deep study of the law and his long experience with its practice in Britain. He writes clearly and cogently. The principles he adduces are applicable to all democratic counties even if their legal systems differ from Britain's.
