83In addition, the Court has held that, since the GDPR does not contain any provision intended to define the rules on the assessment of the damages payable under the right to compensation enshrined in Article 82 of that regulation, national courts must, to that end, apply, in accordance with the principle of procedural autonomy, the domestic rules of each Member State relating to the extent of financial compensation, provided that the principles of equivalence and effectiveness of EU law, as defined by the settled case-law of the Court, are complied with (see, to that effect, judgment of 4 May 2023, Österreichische Post (Non-material damage in connection with the processing of personal data), C‑300/21, EU:C:2023:370, paragraphs 53, 54 and 59).
