46When, in regulating purely internal situations, domestic legislation seeks to adopt the same solutions as those adopted in EU law in order, for example, to avoid discrimination against foreign nationals or any distortion of competition or to provide for a single procedure in comparable situations, it is clearly in the interest of the Union that, in order to forestall future differences of interpretation, provisions or concepts taken from EU law should be interpreted uniformly, irrespective of the circumstances in which they are to apply. Thus, an interpretation by the Court of provisions of EU law in purely internal situations is warranted on the ground that they have been made applicable by national law directly and unconditionally, in order to ensure that internal situations and situations governed by EU law are treated in the same way (judgments of 21 December 2011, Cicala, C‑482/10, EU:C:2011:868, paragraphs 18 and 19, and of 21 November 2019, Deutsche Post and Others, C‑203/18 and C‑374/18, EU:C:2019:999, paragraph 37).
