CONF 003 VIII.21
Procedure for the eventual deletion from the World Heritage List of properties in case of deterioration leading to the loss of the characteristic which determined their inclusion (Document CC-79/CONF.003/10)
With respect to the source of information on the deterioration of a world heritage site, the Committee presumed that it would in most cases be the State Party on whose territory the property was located which would transmit such information to the Secretariat. However, information on the deterioration of a site may be made available by other sources and it would be for the Secretariat to check, as far as possible, on the source of the information and on the substance in consultation with the State Party concerned. The Committee requested the Secretariat in such cases to inform the Chairman of the results of its investigations and decided that it would be incumbent on the Chairman to decide whether the information received should be acted upon.
