Salus populi suprema lex esto (Latin: "The health (welfare, good, salvation, felicity) of the people should be the supreme law", "Let the good (or safety) of the people be the supreme (or highest) law", or "The welfare of the people shall be the supreme law") is a maxim or principle found in Cicero's "De Legibus" (book III, part III, sub.
 VIII).
The Treaty on the Prohibition of Nuclear Weapons, or the Nuclear Weapon Ban Treaty, is the first legally binding international agreement to comprehensively prohibit nuclear weapons, with the goal of leading towards their total elimination.
 It was passed on 7 July 2017.
 In order to come into effect, signature and ratification by at least 50 countries is required.
 For those nations that are party to it, the treaty prohibits the development, testing, production, stockpiling, stationing, transfer, use and threat of use of nuclear weapons, as well as assistance and encouragement to the prohibited activities.
 For nuclear armed states joining the treaty, it provides for a time-bound framework for negotiations leading to the verified and irreversible elimination of its nuclear weapons programme.
Holger Aagaard Hammerich (20 November 1845 – 4 October 1915) was a Danish engineer and politician for the party Højre.
 He played a significant role in the foundation of the Freeport of Copenhagen in the 1890s as well as in the planning of rail lines and stations in Copenhagen.
 He was a member of the Danish Parliament from 1890 until his death in 1915 and represented his party in the negotiations leading up to the amendment of the Danish Constitution in 1915.
The Constitutional Act of the Kingdom of Denmark (Danish: "Danmarks Riges Grundlov" ), or simply the Constitution (Danish: "Grundloven" ), forms a part of the supreme law of Kingdom of Denmark, applying equally in Denmark, Greenland and the Faroe Islands.
 It lays down the framework defining fundamental political principles of governance and establishes the structure, procedures, powers and duties of government institutions.
 Later sections set out fundamental rights and the duties of citizens, such as freedom of speech, freedom of religion and compulsory military service.
The Norwegian Code (Norwegian: "Norske Lov" , abbreviated NL) is the oldest part of the Norwegian law still in force, partially in force in Norway, Iceland, and the Faroe Islands.
 It was given by Christian V of (Denmark and) Norway on 15 April 1687 and entered into force on 29 September 1688, as the legal code for the Kingdom of Norway including its dependencies (the Faroe Islands, Iceland, and Greenland).
 Norway was a nominally sovereign kingdom, but politically (although not economically) the weaker part in a personal union with Denmark at the time.
 The Norwegian Code was largely based on the Danish Code ("Danske Lov", DL), promulgated in 1683 and itself mostly based on older Danish laws, but the Norwegian Code had some differences from the Danish Code in some areas, such as inheritance law, agricultural law, law relating to hunting, fisheries and trade, and military issues.
 In the 19th and 20th centuries, most of the provisions were gradually repealed as they were replaced by modern laws.
 The code as such remains in force, and it was last amended on 1 January 1993.
 As late as the postwar era, the Supreme Courts of Denmark and Norway interpreted identical provisions from the Danish and Norwegian Code respectively; they came to the opposite conclusions regarding the meaning of identical provisions NL 6-10-2 (in force in Norway until 1985) and DL 6-10-2 (still in force in Denmark).
 The provision is ambiguously worded and regulates compensation for damage caused by livestock and dogs.
 The Supreme Court of Norway ruled on the meaning of this provision in 1954.

 Ao then served as the first Chief Minister of Nagaland until August 1966.
