This chapter addresses various dimensions of relations. These comprise the relations of values to each other (for instance the question of the ranking of values), the relation to other provisions of EU law (covering both primary and secondary EU law), as well as the relation to other concepts. The latter category comprises the relation of values to economic and political objectives, as well as the relation of values to selected (legal and ethical) principles. These selected (legal and ethical) principles comprise the protection of vulnerable people, responsibility (including the question of human rights and human obligations), precaution, sustainability, as well as proportionality and balance.
