You have to know its constitution, any subject that aspires to become a citizen must do, this book will help us and helps digest this very indigestible thing called the constitution. I will quote the words in the preface that illustrate the author's style: "The book is intended objective; he did not want neutral, especially in the field of value judgments, the author not expect, I am sure, a unanimous support. " This is well summarized the author is not neutral, for example I do not share his opinion on the deletion of the reference to the treason of Article 68 of the comment 440, which has been removed knowingly and yet was fraught with meaning and not as mysterious as the author claims, it must be embedded in the constitutional right not to see this big nose on your face. However, this lack of neutrality is not unpleasant and instead gives life to a work that could have been undrinkable, which is not the case. The index end of the book is welcome, the absence of summary lot less, too bad! Caution is still technical neophytes like me swim sometimes.
