Page "Referendum" Paragraph 77

The Norwegian Constitution does not mention refendums at all, and as such, referendums are not a part of Norwegian political practice.

However, six advisory referendums have been held in Norway, most notably, the referendums on Norwegian EU membership, and the referendum for dissolving the union with Sweden.

It is worth noting that these referendums, and potential future referendums, although legitimate as part of Norwegian constitutional convention, will not have any legal binding: They will merely be advisory, and the final decision will be taken by the Norwegian parliament, who may choose ( albeit unlikely ) to disregard the will of the Norwegian people as expressed through the referendum.
