Crown copyright
Crown copyright is a type of copyright protection. It subsists in works of the governments of some Commonwealth realms and provides special copyright rules for the Crown, i.e. government departments and (generally) state entities. Each Commonwealth realm has its own Crown copyright regulations. There are therefore no common regulations that apply to all or a number of those countries. There are some considerations being made in Canada, UK, Australia and New Zealand regarding the "reuse of Crown-copyrighted material, through new licences".
