The President of the Etablissement Français du Sang submits the draft regional plan for an opinion, by any means which confers a date of receipt, to each regional health agency concerned and to the Minister for Health, as well as, where an army hospital or other element of the army health service is concerned, to the Minister for Defence. The opinions of the Regional Health Agency, the Minister for Health and, where applicable, the Minister for Defence are forwarded to the President of the Etablissement Français du Sang within two months of the date of receipt of the project by each of these authorities. If no response is received within this period, this constitutes a favourable opinion.
