The U.S. Supreme Court Pink (1942) found that international agreements, which were concluded in law, have the same legal status as treaties and do not require Senate approval. To Reid v. Concealed (1957), the Tribunal, while reaffirming the President`s ability to enter into executive agreements, found that such agreements could not be contrary to existing federal law or the Constitution. In a federal or dependent territory, the same role is played by the holder of a function equivalent to that of a head of state. In each Canadian province, for example, the role is assumed by the lieutenant governor, while in most British overseas territories, powers and duties are assumed by the governor. The same is true for the states of Australia, the Indian states, etc. The Hong Kong Constitutional Document, the Basic Law, for example, defines the Director General as head of the Special Administrative Region, in addition to his role as Head of Government. However, these non-sovereign heads of state play little or no role in diplomatic affairs, depending on the status and standards and practices of the territories concerned. What the signing of the Treaty means The Convention and the Optional Protocol provide for a simple signing procedure. This means that no legal obligation is imposed on a signatory state or a regional integration organisation immediately after the contract is signed. However, by signing the Convention or the Optional Protocol, states or regional integration organizations indicate their intention to take treaty-related measures at a later date. The signature also creates the obligation to abstain, between the signature and ratification or the period of attribution or consent, of acts that would nullify the purpose and purpose of the treaty.

In many countries, official portraits of the head of state can be found in government offices, courts or other public buildings. The idea, sometimes framed by law, is to use these portraits to draw public attention to the symbolic link with the government, a practice that dates back to the Middle Ages. Sometimes this practice is taken too much and the head of state becomes the most important symbol of the nation, which leads to the emergence of a cult of the person in which the image of the head of state is the only visual representation of the country and exceeds other symbols such as the flag. An executive agreement[1] is an agreement between heads of government of two or more nations that has not been ratified by the legislature, since the treaties are ratified.
