I am very interested in understanding the significance of the Lisbon Treaty and its impact upon the previously existing treaties. In my research, I did not find many useful materials. There is an abundance of propoganda that I, as a Professor, have no interest. However, this publication, as a few [and I emphasise few], stood above the mediocre writings in this area. I found it useful for my work, in preparing a synopsis of the Lisbon Treaty. The "dividing line between the Union and the Member States" is almost intractable. This book provides a certain level of clarity to identify the division of power, and serves as a platform for further study of this key issue.
