The 1961 Vienna Convention on Diplomatic Relations has for over 50 years been central to diplomacy and applied to all forms of relations among sovereign States. Participation is almost universal. The rules giving special protection to ambassadors are the oldest established in international law and the Convention is respected almost everywhere. But understanding it as a living instrument requires knowledge of its background in customary international law, of the negotiating history which clarifies many of its terms and the subsequent practice of states and decisions of national courts which have resolved other ambiguities. Diplomatic Law provides this in-depth Commentary. The book is an essential guide to changing methods of modern diplomacy and shows how challenges to its regime of special protection for embassies and diplomats have been met and resolved. It is used by ministries of foreign affairs and cited by domestic courts world-wide. The book analyzes the reasons for the widespread observance of the Convention rules and why in the special case of communications - where there is flagrant violation of their special status - these reasons do not apply. It describes how abuse has been controlled and how the immunities in the Convention have survived onslaught by those claiming that they should give way to conflicting entitlements to access to justice and the desire to punish violators of human rights. It describes how the duty of diplomats not to interfere in the internal affairs of the host State is being narrowed in the face of the communal international responsibility to monitor and uphold human rights.

This book brings together world experts on the United Nations and international law, to examine not only the content of that legal regime but how it has been transformed since the second half of the twentieth century.

The 1969 and 1986 Vienna Conventions on the Law of Treaties are essential components of the international legal order. This is the first Commentary on their provisions, containing thorough and well-structured analyses of each of their Articles. It draws on preparatory works and practice and is written by a large collection of experts from the field

Even over 50 years after its entry into force, the Vienna Convention on Diplomatic Relations of 1961 remains as important as ever and enjoys a high level of acceptance worldwide. Over 190 states have acceded to the Convention and apply its provisions in their daily diplomatic work. These comprehensively revised and updated commentaries provide those who apply the law with practical explanations on the Vienna Convention's provisions. Key topics such as diplomatic immunity, the inviolability of the diplomatic mission and the protection of diplomatic couriers are addressed here in detail, with particular regard to German legislation and jurisprudence on such issues. The commentaries are rounded off by comprehensive information derived from the day-to-day work of the Federal Foreign Office and other foreign services.

Diplomatic interference carries considerable potential for disruption. In this context, diplomats have been accused of insulting behaviour, the funding of political parties, incitement to terrorism and even attempts to topple the host government. Reactions can be harsh: expulsions are common and, occasionally, diplomatic relations are severed altogether. But an evaluation under international law faces challenges. Often enough, charges of interference are made when legitimate interests are involved – for instance, when diplomats criticise the human rights record of their hosts. In such cases, diplomats may be able to invoke grounds which are recognised under international law. On the basis of more than 300 cases of alleged diplomatic interference and the practice of about 100 States and territories, Diplomatic Interference and the Law provides an examination of the main areas in which charges of meddling have arisen – such as lobbying activities, contacts with the opposition, propaganda, the use of threats and insults and the granting of asylum. It analyses situations in which the sovereignty of the receiving State meets competing interests and offers solutions which avoid a conflict of norms. It concludes with useful advice for foreign offices and diplomatic agents and underlines the most efficient ways of dealing with situations of alleged interference. ''A book that is here to stay! It is essential reading for diplomats, academics, journalists, students and everyone who has an interest in international law and justice. Based on rigorous research, Paul Behrens' book offers new and thoughtful perspectives on the Vienna Convention on Diplomatic Relations which we drafted in 1961. It demonstrates just how important it is to have a lawyer of his impartiality and integrity if we want to reach peaceful and lasting solutions in international relations. Diplomatic Interference and the Law has the makings of an instant classic, and I have no doubt that it will pave the way for the sorely needed reform of diplomatic law.'' Dr Nelson Iriñiz Casás, Vice President of the Committee of the Whole of the Vienna Conference on Diplomatic Relations in 1961; former Head of the diplomatic missions of Uruguay to Austria, Czechoslovakia, Hong Kong, Denmark and Sweden; author of Corrupción en la ONU. ''Dr Behrens's book rigorously analyses the legal doctrine of non-interference by diplomats in their hosts' internal affairs, and how it may conflict with legal obligations to combat, for example, denial of self-determination and breaches of human rights. Exhaustively researched and in accessible language, with copious, often entertaining examples, it will be an indispensable guide for diplomats. "Behrens on diplomatic interference" will be cited as the definitive authority on the matter for the foreseeable future. I recommend this book to diplomats, lawyers and the general reader: they will all read and refer to it with profit and immense pleasure.'' Sir Brian Barder KCMG, BA (Cantab.), is a former British ambassador to Ethiopia, Bénin and Poland and High Commissioner to Nigeria and Australia. ''Paul Behrens' book breaks new ground. It is the first study to focus on the vexed question of diplomatic 'meddling' in the domestic affairs of the receiving State. It has heightened topicality as many Western governments in their concern to promote human rights and democracy urge their diplomats to be active in their support of civil society, particularly in countries with authoritarian governments. This book is replete with case studies covering the 50 years since the signature of the Vienna Convention and provides an invaluable pathway through this legal minefield.''
