Membership in the Royal Victorian Order is conferred by the reigning monarch without ministerial advice on those who have performed personal service for the sovereign, any member of his or her family, or any of his or her Governors-General. All living citizens of any Commonwealth realm, including women since 1936, are eligible for any of the five levels of the order, save for Canadians: as admission to the top two levels of the organisation provides for an honorary prefix, Canadians are not normally appointed to these levels as long as the monarch's Canadian ministry adheres to the Nickle Resolution of 1919.
