52As regards Article 4 TEU, it should be recalled that according to settled case-law, under the principle of sincere cooperation laid down in paragraph 3 of that article, it is for the Member States to ensure judicial protection of an individual’s rights under EU law (see, to that effect, inter alia the judgment in Unibet, C‑432/05, EU:C:2007:163, paragraph 38). In addition, Article 19(1) TEU requires Member States to provide remedies sufficient to ensure effective legal protection in the fields covered by EU law.
