The Queen-in-Council (during the reign of a male monarch, King-in-Council) is a technical term in a number of states.
In Norway, the "King in Council" (Norwegian: Kongen i statsråd) refers to the meetings of the King and the Council of State (i.e. the Cabinet) where matters of importance and major decisions are made. The council meets at the Royal Palace and is normally held every Friday. It is chaired by the King or, if he is ill or abroad, the Crown Prince. In Norway's Constitution, references to the King, when formulated as King in Council (Kongen i Statsråd) refers to the formal Government of Norway. When the formulation is merely King, the appointed ministerium that the law refers to may alone act with complete authority of the matter assigned in the particular law.
A decision that is taken in the State Council under the King's leadership is a royal decree. If the Crown Prince chairs, they are Crown Prince resolutions. When neither the King nor the Crown Prince chairs, resolutions adopted are called Government resolutions.
In Sweden, the King in Council (Swedish: Konungen i Statsrådet, or more commonly known as Royal Majesty, (Kunglig Majestät or the short form Kungl.Maj:t or K.M:t. in Swedish) was a term of constitutional importance in Sweden before 1975.
Royal Majesty was the commonly used term to refer to the supreme executive authority under the 1809 Instrument of Government: where the King made all decisions of state in the presence of his cabinet ministers. The 1974 Instrument of Government removed the monarch from all exercise of formal political powers and created its successor: the Government (Swedish: Regeringen) chaired and led in all aspects by the Prime Minister.
The Queen-in-Council is the technical term of constitutional law for the exercise of executive authority in a Commonwealth realm, denoting the monarch acting by and with the advice and consent of his or her privy council (in the United Kingdom and Canada's federal jurisdiction) or executive council (in most other Commonwealth realms, Australian states, and in Canadian provinces). In those realms and dependencies where the Queen's powers and functions are delegated to a governor-general, lieutenant governor, or governor, the term Governor-General-in-Council, Lieutenant-Governor-in-Council, or Governor-in-Council may be used instead of Queen-in-Council, respectively, although all of these terms describe the same technical process within constitutional law. "The government of [jurisdiction]" is commonly used as a synonym for any of the aforementioned terms, though the phrase may mean more than one thing in certain areas.
