In the first case the interim government acted until the Storting and the Swedish Legislative Assembly had decided upon the regency for the period until the successor reached the age of majority.
The interim government consisted of equal numbers of Norwegian and Swedish ministers, usually ten from each country. The Swedish and the Norwegian prime minister alternately presided; the order between them decided by drawing lots. By constitutional amendment of 20 January 1863 it was decided that the prince next in the order of succession should be regent if he had reached the age of majority.
In periods with interim governments additional Norwegian ministers were appointed both in Stockholm and Christiania, in the latter case to replace ministers travelling to Stockholm to supplement the Council of State Division there.
