The granting of aid, the principle of which has been accepted, is subject to the issue of authorisations.
Prior authorisation is issued before the work is completed. It sets out the terms and conditions for payment of the grant.
A final authorisation is issued once the work has been completed. This authorisation constitutes the final decision to award the grant. It establishes, where applicable, eligibility for the bonuses or increases provided for in articles 311-44,311-49 and 311-51.
