40In so far as Article 15(1) of Directive 2002/58 permits Member States to adopt legislative measures that ‘restrict the scope’ of the rights and obligations laid down inter alia in Articles 5, 6 and 9 of that directive, such as those arising from the principles of confidentiality of communications and the prohibition on storing related data recalled in paragraph 35 of this judgment, that provision provides for an exception to the general rule provided for inter alia in Articles 5, 6 and 9 and must thus, in accordance with settled case-law, be the subject of a strict interpretation. That provision, therefore, cannot permit the exception to the obligation of principle to ensure the confidentiality of electronic communications and data relating thereto and, in particular, to the prohibition on storage of that data, laid down in Article 5 of that directive, to become the rule, if the latter provision is not to be rendered largely meaningless (see, to that effect, judgments of 21 December 2016, Tele2 Sverige and Watson and Others, C‑203/15 and C‑698/15, EU:C:2016:970, paragraph 89, and of 6 October 2020, La Quadrature du Net and Others, C‑511/18, C‑512/18 and C‑520/18, EU:C:2020:791, paragraph 111).
