NatureScot appear to imply they don't need an objective to refuse a license application but Natural Heritage (Scotland) Act 1991 provides them with general aims - "Section 1.(1A) SNH 's general aims and purposes in relation to natural heritage are - (a)to secure the conservation and enhancement of; and (b)to foster understanding and facilitate the enjoyment of, the natural heritage of Scotland; and SNH shall have regard to the desirability of securing that anything done, whether by SNH or any other person, in relation to the natural heritage of Scotland is undertaken in a manner which is sustainable."
