In the meantime, 1007 World Heritage Sites have been inscribed on the World Heritage List （as of February 2015） and two sites have been delisted. This paper discusses the delisting procedure of a site from the World Heritage List based on the Operational Guidelines for the Implementation of the World Heritage Convention （henceforth OG）. First of all, the question of the possibility to delist a site from the World Heritage List, in general, is addressed. And based on this discussion, the necessity of the consent of the State Party to the WHC on whose territory the site to be delisted is located is then examined.展开更多
