53As regards the assessment of the compensation payable under Article 82 of the GDPR, since that regulation does not contain a measure having such an aim, the national courts must, for the purpose of that assessment, apply the internal rules of each Member State relating to the extent of the pecuniary compensation, to the extent that the principles of equivalence and effectiveness of EU law can be observed (see, to that effect, judgment of 21 December 2023, Krankenversicherung Nordrhein, C‑667/21, EU:C:2023:1022, paragraphs 83 and 101 and the case-law cited).
