International law is traditionally concerned with inter-state relations, but nowadays it involves likewise international organisations and, to a lesser extent, also natural and legal persons. The course provides a broad understanding of the central principles and main branches of international law, e.g. jurisdiction, immunity, state responsibility, peaceful settlement of disputes, law of treaties, diplomatic law, law of the sea and use of armed force. In addition to the theoretical foundation, relevant practices of states, courts and international organisations are examined in connection with discussed topics.
Diplomatic and consular law began to develop with the earliest civilizations and therefore are among the oldest parts of international law. Since then, diplomatic and consular relations have become important means of communication and dispute settlement. These relations are effective means for states to protect the interest of their own and of their nationals abroad. In addition to classical diplomatic and consular relations, states have sent special missions with a limited task. The last century has introduced a new type of formalised relations involving international organisations. The course gives a broad understanding of the legal regulation of diplomatic, consular and other similar relations (e.g. establishment of relations and missions, functions, privileges and immunities of missions and their personnel, remedies against abuses) as well as of relevant state and court practice.
