King in Council, or Royal Majesty, (most formally Konungen i Statsrådet, but a term for it most often used in legal documents was Kunglig Majestät or short form Kungl.Maj:t or K.M:t. in Swedish) was a term of constitutional importance that was used in Sweden before 1975 when the 1974 Instrument of Government came into force.
Royal Majesty denoted several functions, but most importantly, it was the commonly used term that designated 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.
When there was no person in line to the throne available, the Council of State alone again could reign in the king's or the crown's name.
[2] The same rules are today used in the new Instrument of Government when the king is unable to fulfil his duties, but the title now is riksföreståndare, instead of Regent.
The different uses of the term Kunglig Majestät were thus: Today, with the exception of remnants of previous usage, the term Royal Majesty is at present in Sweden only used for Royal orders of knighthood, Kunglig Majestäts Orden.
