This chapter examines the rules of international law governing the birth, the life, and the death of treaties. Treaties, a formal source of international law, are agreements in written form between States or international organizations that are subject to international law. A treaty falls under the definition of the Vienna Convention on the Law of Treaties (VCLT), no matter what form or title it may have. The most important factor is that it sets out obligations or entitlements under international law. The VCLT enumerates the rules governing the ‘birth’, ie the steps from the negotiation until the entry into force of the treaty; the ‘life’, ie the interpretation and application of the treaty; and its ‘demise’, ie its termination. The two fundamental tenets are, on the one hand, the principle ‘pacta sunt servanda’ and, on the other, the principle of contractual freedom of the parties.

The question of reservations was one of the ‘controversial issues’ facing the Third United Nations Conference on the Law of the Sea in drawing up the final clauses of the Convention. On the one hand it was argued that the integrity of the Convention must be safeguarded and that the ‘package deal’ must be protected from possible disintegration by the making of reservations. On the other hand the view was held that ‘allowance for the possibility of reservations is aimed at accommodating the views of the delegations who have maintained that they cannot become parties to the Convention unless the Convention permits them to exercise a right to enter reservations, in accordance with customary international law and as envisaged under the Vienna Convention on the Law of Treaties.’ In short the need to preserve the integrity of the Convention was pitted against the need to secure universal participation in the Convention.

Treaties are an important source of international law that are used with increasing frequency to codify, crystallise and develop international law. They are particularly useful when States need to change or reorganise their obligations under international law rapidly, sometimes to reflect the changed reality of international society. This chapter begins with the definition of a treaty. It then discusses the Vienna Convention on the Law of Treaties 1969; formation and application of treaties; reservations to treaties; interpretation of treaties; invalidity of treaties; and termination of treaties.

This chapter describes the law of treaties. As defined in Article 2(2) of the Vienna Convention on the Law of Treaties (VCLT), a treaty can be embodied in a single instrument, or in two or more related instruments. It is a written agreement; between international legal subjects; and governed by international law. In short, a treaty must be written in order to fall under the scope of the VCLT. Though this does not mean that oral agreements have no effect in international law, it does mean that the law of treaties embodied in the VCLT does not govern oral agreements. While States are the most active actors entering into treaty relations, international organizations may also enter into treaties, whether between them or with a State. Ultimately, because a treaty’s purpose is to create binding international legal obligations, the law of treaties applies to agreements governed by international law.

This chapter discusses the interpretation of the Energy Charter Treaty. The ECT is a multilateral treaty during the negotiation of which approximately fifty States participated, albeit to varying degrees. It goes without saying that in such a setting, there are many competing interests to take into account, often resulting in ambiguous treaty provisions. Indeed, almost every dispute based on the ECT involves issues of treaty interpretation. The law applicable to the interpretation of treaties is international law, unless the parties to the treaty in question have agreed otherwise. For all practical purposes, the most important international document when it comes to treaty interpretation is the 1969 Vienna Convention on the Law of Treaties. Article 2(1)(a) of the Vienna Convention defines ‘treaty’ as ‘an international agreement concluded between States in written form and governed by international law, whether embodied in a single instrument or in two or more related instruments and whatever its particular designation’. There is little doubt that the ECT is covered by this definition. Article 26(6) of the ECT provides that disputes under it are to be resolved on the basis of its provisions and ‘applicable rules and principles of international law’. The chapter then considers Articles 31—3 of the Vienna Convention, which deal with the interpretation of treaties.

The text of Przemysław Saganek is a part of a wider discussion on the Mediterranean migration crisis. The author underlines the multi-aspect character of the crisis and the fact that several branches of international law which are at stake in it. They cover: the law on refugees, human rights, the law of the sea, the maritime law, the rules on territorial sovereignty and on the crossing of borders. What is of importance are customary norms, treaties and norms of the EU law. The idea of the author is to look at the instruments of international law which may act as incentive for hundreds of thousands of newcomers or as main obstacles for the states to put an end to uncontrolled inflow of people through their borders. His idea is to identify such instruments and start discussion on their possible suspension or termination if the crisis persists. The author comes to the conclusion that the definition of a refugee from the 1951 Geneva Conventionis not by itself a source of problems. The same concerns the subsidiary protection as introduced by the EU qualification directive. The same can be said about the scope of rights of persons covered by the international protection. The only element which requires discussion is the possible redefinition of the right to national treatment as regards the social aid. On the other hand, the scope of powers of states to defend their borders depends on the interpretation of the EU instruments on the protection of borders and the rights of applicants for international protection. The author comes to the conclusion that neither the procedural directive, nor the 2016 Schengen Border Code can be interpreted as a source of the right of an applicant to enter the territory of a Member State. On the other hand, the geographical conditions and the law of the sea make Greece and Italy the most vulnerable for the inflow of persons. The necessity of important changes to the law and its interpretation are referred to in a general way.

The second part of the article concerns the interpretation and application in the central parts of Poland of the provisions of the Napoleonic Code on vacant inheritances. The Code does not provide a definition of the vacant inheritance. The key to the interpretation of the provisions on the acquisition of vacant inheritances by the state is the term “is presumed to be” (a vacant inheritance) used in the former Article 811 of the Napoleonic Code (French: est réputée vacante), see the current Article 809 of the French Civil Code which omits the term “is presumed to be”).This indicates that, in the absence of suitable heirs, the law introduced a specific rebuttable presumption of a vacant inheritance, belonging to the state. Only after an appropriate period of time did the presumption turn into certainty, i.e. it resulted in the inability to invoke the inheritance title. In practice, this meant that thirty years after the time necessary to draw up an inventory of the inheritance and to deliberate (ad deliberandum), the inheritance ultimately fell to the State. The mechanism adopted in the Napoleonic Code made it possible, on the one hand, for the heir to acquire the inheritance, which remained under the supervision of a curator for the period when it was presumed vacant, and on the other hand, it prevented the existence of inheritances without a claimant, i.e. inheritances devoid of the persons entitled to take them over. In the post-war period, when the communist authorities passed subsequent legal acts concerning the provisions of the inheritance law, the deadlines for heirs to apply for inheritance changed. Ultimately, the legislator did not adopt the model of vacant inheritances in the regulations harmonising the inheritance law on the Polish lands since 1947; instead, a solution analogous to the one provided for in the German Civil Code of 1986 (BGB) was adopted. The “shortening” of the statute of limitations also influenced the assessment of the admissibility of further application of the provisions of the Napoleonic Code in regard to vacant inheritances during the period of the People’s Republic of Poland regime (despite the existence of different inheritance law solutions).

This chapter deals with the codification efforts of the International Law Commission (ILC). It analyzes three law of treaties Conventions that were drafted by the ILC. First, it analyzes the most successful of all the Conventions, the 1969 Vienna Convention on the Law of Treaties. It mostly has codified existing norms of customary international law but also introduced, inter alia, a revolutionary regime of reservations to treaties and dealt with a controversial (at the time) notion of the norms of jus cogens. This Convention has acquired an iconic status in international law and has become the most significant tool regulating the relations between states. The 1986 Vienna Convention on the Law of Treaties between States and International Organizations or between International Organizations has never entered into force. It has not proven as successful as its predecessor due to certain unresolved questions relating generally to the functions of international organizations. The 1978 Vienna Convention on Succession of States in respect of Treaties has entered into force; however, due to complexities of state succession in general, it has not played a prominent role, regulating mostly succession in respect of treaties of newly independent, post-colonial states. Finally, the chapter also analyzes Draft Articles adopted by the ILC in 2011 on Effects of Armed Conflicts on Treaties. The form to be given to the Articles is under consideration and governments are invited to comment on any future action regarding them. The list of categories of treaties in the annex suggests that due to its subject matter they will continue to operate, in whole or in part, in the event of armed conflict.
