In addition to treaties, there are other, less formal international agreements. These include efforts such as the Proliferation Security Initiative (PSI) and the G7 Global Partnership Against the Spread of Mass Destruction. Although the PSI has a “Declaration of Prohibition Principles” and the G7 Global Partnership, several G7 leaders` declarations, neither has a legally binding document, which sets out specific commitments and is signed or ratified by member states. See the article on the Bricker Amendment for the history of the relationship between treaty powers and constitutional provisions. The end of the preamble and the beginning of the agreement itself are often referred to as “agreed as follows”. WorldLII`s International Treaties Collection (Open Access) contains the full texts of more than 60,000 contracts (€30,000 from the United Nations Collection). They are both multilateral and bilateral (many countries), in 27 databases from many sources and several LIPs. The Vienna Convention on Contract Law defines a “treaty” as “an international agreement concluded in writing between States and subject to international law, whether it appears in a single act or in two or more related acts and under any name whatsoever” (Article 2, paragraph 1, point (a)). While the Vienna Convention provides for a general dispute settlement mechanism, many contracts define a procedure outside the dispute settlement agreement and alleged infringements.
This may be done by a body specially convened in respect of a tribunal or body established for that purpose, such as the International Court of Justice, the European Court of Justice or procedures such as the understanding of dispute resolution by the World Trade Organization. Depending on the contract, such proceedings may give rise to fines or other enforcement measures. A party may require that a contract be terminated, even without an express provision, if circumstances have changed dramatically. Such a change is sufficient if it is unforeseen, if it undermines the “essential basis” of a party`s agreement, if it radically alters the scope of the commitments between the parties and if the commitments still have to be respected. A party may not base this assertion on changes caused by its own infringement. Nor can this declaration be used to invalidate treaties that have set or redefined political boundaries. This series refers to or is based on financial and monetary principles established in 1944 at a meeting of allied nations in the American city of Bretton Woods. This series is available on HEIN Online (Vol 1, 1962) in the Law Journal Library Collection and JSTOR (Vol 1, 1962). It is not a number of contracts, but it contains contractual texts and useful introductory information about contracts, and it is an accepted method of citation.
Note that JSTOR shares are more current than HEIN. Bilateral agreements are concluded between two States or entities.  A bilateral treaty may have more than two parties; Thus, each bilateral treaty between Switzerland and the European Union (EU) has seventeen parts: the parties are divided into two groups: the Swiss (“on the one hand”) and the EU and its member states (“on the other”). . . .
