§ 3.0 Overview of International Organisations. Conventions are complex contracts among states or interstate organisations which mutually regulate their behaviors. Public international laws in the aggregate establish functions for these relationships. Most conventions are administered by an organisation agreed upon by the contracting states. A mature international organisation has a permanent body to manage the organisation and further its objectives, a membership comprising at least two states and an organisation which pursues a common aim of its members.1 International organisations develop policies and promote them to the end of peaceful and rational global governance.2 International organisations thus provide structural points connecting the functional lines of the public laws. The organisations regulated by public international laws relevant to the shipmaster develop, encourage, promulgate and manage conventions, protocols and regulations for states to adopt or to adapt to their own needs. The most important international organisations are the UN groups of entities. Each of these entities has a legal personality and is capable of entering into agreements with other legal persons. The bodies associated with the UN act independently of that body while coordinating with it. Other entities peripheral to the UN bodies are also important. There are thousands of governmental, intergovernmental, private and other international organisations.3 The ones concerning us here are those which affect the shipmaster.
