There are two articles in the Norwegian Constitution related to culture: Firstly, Article 100 which guarantees freedom of expression (English version updated in June 2015):
There shall be freedom of expression.
No one may be held liable in law for having imparted or received information, ideas or messages unless this can be justified in relation to the grounds for freedom of expression, which are the seeking of truth, the promotion of democracy and the individual’s freedom to form opinions. Such legal liability shall be prescribed by law.
Everyone shall be free to speak their mind frankly on the administration of the State and on any other subject whatsoever. Clearly defined limitations to this right may only be imposed when particularly weighty considerations so justify in relation to the grounds for freedom of expression.
Prior censorship and other preventive measures may not be applied unless so required in order to protect children and young persons from the harmful influence of moving pictures. Censorship of letters may only be imposed in institutions.
Everyone has a right of access to documents of the State and municipalities and a right to follow the proceedings of the courts and democratically elected bodies. Limitations to this right may be prescribed by law to protect the privacy of the individual or for other weighty reasons.
The authorities of the state shall create conditions that facilitate open and enlightened public discourse.
Secondly, Article 108 of the Constitution deals with the responsibilities vis-à-vis the Sami people:
The authorities of the state shall create conditions enabling the Sami people to preserve and develop its language, culture and way of life
