47In its settled case-law on the EEC Treaty, the Court has held that, unlike standard international treaties, the Community Treaties established a new legal order, integrated into the legal systems of the Member States on the entry into force of the Treaties and which is binding on their courts. The Member States have limited, in the fields defined by the Treaties, their sovereign rights, for the benefit of that new legal order possessing its own institutions and whose subjects comprise not only Member States, but also their nationals (see, to that effect, judgments of 5 February 1963, van Gend & Loos, 26/62, EU:C:1963:1, p. 12; of 15 July 1964, Costa, 6/64, EU:C:1964:66, pp. 593 and 594; and of 21 December 2021, Euro Box Promotion and Others, C‑357/19, C‑379/19, C‑547/19, C‑811/19 and C‑840/19, EU:C:2021:1034, paragraph 245).
