Public international law in the context of "American Journal of International Law"

A number of polities have declared independence and sought diplomatic recognition from the international community as sovereign states, but have not been universally recognized as such. These entities often have de facto control of their territory. A number of such entities have existed in the past.

There are two traditional theories used to indicate how a sovereign state comes into being. The declarative theory (codified in the 1933 Montevideo Convention) defines a state as a person in international law if it meets the following criteria:

Diplomatic recognition in international law is a unilateral declarative political act of a state that acknowledges an act or status of another state or government in control of a state (may be also a recognized state). Recognition can be accorded either on a de facto or de jure basis. Partial recognition can occur if many sovereign states refuse to recognize an entity as a peer. Recognition can be a declaration to that effect by the recognizing government or may be implied from an act of recognition, such as entering into a treaty with the other state or making a state visit. Recognition may, but need not, have domestic and international legal consequences. If sufficient countries recognize a particular entity as a state, that state may have a right to membership in international organizations, while treaties may require all existing member countries unanimously agreeing to the admission of a new member.

A vote by a country in the United Nations in favour of the membership of another country is an implicit recognition of that country by the country so voting, as only states may be members of the UN. On the other hand, a negative vote for UN membership does not necessarily mean non-recognition of the applicant as a state, as other criteria, requirements or special circumstances may be considered relevant for UN membership. Similarly, a country may choose not to apply for UN membership for its own reasons, as is the case with Vatican City, and Switzerland was not a member until 2002 because of its concerns to maintain its neutrality policy.

The legal status of the Holy See, the ecclesiastical jurisdiction of the Catholic Church in Rome, both in state practice and according to the writing of modern legal scholars, is that of a full subject of public international law, with rights and duties analogous to those of states.

International criminal law (ICL) is a body of public international law designed to prohibit certain categories of conduct commonly viewed as serious atrocities and to make perpetrators of such conduct criminally accountable for their perpetration. The core crimes under international law are genocide, war crimes, crimes against humanity, and the crime of aggression.

Classical international law governs the relationships, rights, and responsibilities of states. After World War II, the Charter of the International Military Tribunal and the following Nuremberg trial revolutionized international law by applying its prohibitions directly to individuals, in this case the defeated leaders of Nazi Germany, thus inventing international criminal law. After being dormant for decades, international criminal law was revived in the 1990s to address the war crimes in the Yugoslav Wars and the Rwandan genocide, leading to the establishment of a permanent International Criminal Court in 2001.

International labour law is the body of rules spanning public and private international law which concern the rights and duties of employees, employers, trade unions and governments in regulating work and the workplace. The International Labour Organization and the World Trade Organization have been the main international bodies involved in reforming labour markets. The International Monetary Fund and the World Bank have indirectly driven changes in labour policy by demanding structural adjustment conditions for receiving loans or grants. Issues regarding Conflict of laws arise, determined by national courts, when people work in more than one country, and supra-national bodies, particularly in the law of the European Union, have a growing body of rules regarding labour rights.

International labour standards refer to conventions agreed upon by international actors, resulting from a series of value judgments, set forth to protect basic worker rights, enhance workers’ job security, and improve their terms of employment on a global scale. The intent of such standards, then, is to establish a worldwide minimum level of protection from inhumane labour practices through the adoption and implementation of said measures. From a theoretical standpoint, it has been maintained, on ethical grounds, that there are certain basic human rights that are universal to humankind. Thus, it is the aim of international labour standards to ensure the provision of such rights in the workplace, such as against workplace aggression, bullying, discrimination and gender inequality on the other hands for working diversity, workplace democracy and empowerment.

The Constitution of the Republic of Singapore is the supreme law of Singapore. A written constitution, the text which took effect on 9 August 1965 is derived from the Constitution of the State of Singapore 1963, provisions of the Federal Constitution of Malaysia made applicable to Singapore by the Republic of Singapore Independence Act 1965 (No. 9 of 1965, 1985 Rev. Ed.), and the Republic of Singapore Independence Act itself. The text of the Constitution is one of the legally binding sources of constitutional law in Singapore, the others being judicial interpretations of the Constitution, and certain other statutes. Non-binding sources are influences on constitutional law such as soft law, constitutional conventions, and public international law.

In the exercise of its original jurisdiction – that is, its power to hear cases for the first time – the High Court carries out two types of judicial review: judicial review of legislation, and judicial review of administrative acts. Although in a 1980 case the Privy Council held that the fundamental liberties in Part IV of the Constitution should be interpreted generously, Singapore courts usually adopt a philosophy of deference to Parliament and a strong presumption of constitutional validity, which has led to fundamental liberties being construed narrowly in certain cases. The courts also generally adopt a purposive approach, favouring interpretations that promote the purpose or object underlying constitutional provisions.

The European Stability Mechanism (ESM) is an intergovernmental organization located in Luxembourg City, which operates under public international law for all eurozone member states having ratified a special ESM intergovernmental treaty. It was established on 27 September 2012 as a permanent firewall for the eurozone, to safeguard and provide instant access to financial assistance programmes for member states of the eurozone in financial difficulty, with a maximum lending capacity of €500 billion. It has replaced two earlier temporary EU funding programmes: the European Financial Stability Facility (EFSF) and the European Financial Stabilisation Mechanism (EFSM).

Supranational law is a form of international law, based on the limitation of the rights of sovereign nations between one another. It is distinguished from public international law, because in supranational law, nations explicitly submit their right to make judicial decisions by treaty to a set of common tribunal. The United Nations Security Council and subordinate organizations, such as the International Court of Justice, are the only globally accepted supranational tribunals.
