48In this connection, it should be borne in mind that national legislation and practice, such as those at issue in the main proceedings, which subject remote (telemetric) data-transmission devices lawfully manufactured in other Member States to a metrological verification restrict access to the market of the importing Member State and must therefore be regarded as amounting to a measure having an effect equivalent to a quantitative restriction on imports within the meaning of Article 34 TFEU (see, to that effect, Radiosistemi, C‑388/00 and C‑429/00, EU:C:2002:390, paragraph 43; ATRAL, C‑14/02, EU:C:2003:265, paragraphs 62 and 63; and Commission v Portugal, C‑432/03, EU:C:2005:669, paragraph 41).
