64It must be remembered that unless a derogation is granted, any deterioration of the status of a body of surface water must be prevented. The obligation to prevent such deterioration thus remains binding at each stage of implementation of Directive 2000/60 and is applicable to every surface water body type and status for which a management plan has been adopted. The Member State concerned is consequently required to refuse authorisation for a project where it is such as to result in deterioration of the status of the body of water concerned or to jeopardise the attainment of good surface water status, unless the view is taken that the project is covered by a derogation under Article 4(7) of the directive (see, to that effect, judgment of 1 July 2015 in Bund für Umwelt und Naturschutz Deutschland, C‑461/13, EU:C:2015:433, paragraph 50).
