Adam Roberts in his "Documents on the laws of war", gives another translation confirmed as accurate by the Depositay (because UNESCO does not have an English translation of the reservation made by Norway:
"The return of cultural property in accord with the provisions of Sections I and II of the Protocol cannot be demanded after the end of a period of twenty years, starting from the date when the property concerned came into the possession of a holder in good faith."
