49In that connection, regard must be had to the settled case-law of the Court to the effect that the interpretation which, in the exercise of the jurisdiction conferred on it by Article 267 TFEU, the Court gives to a rule of EU law clarifies and defines the meaning and scope of that rule as it must be or ought to have been understood and applied from the date of its entry into force. It follows that the rule as thus interpreted may, and must, be applied by the courts even to legal relationships which arose and were established before the judgment ruling on the request for interpretation, provided that in other respects the conditions for bringing a dispute relating to the application of that rule before the courts having jurisdiction are satisfied (see judgment in Santander Asset Management SGIIC and Others, C‑338/11 to C‑347/11, EU:C:2012:286, paragraph 58 and the case-law cited).
