EU Internal Market
Give some examples from the CJEU case law.
In Keck the Court drew a seemingly straightforward distinction between selling arrangements and
product requirements and appeared to suggest that the former category of nation regulatory rules
should be exempt from the prohibition under Article 34 TFEU. That prohibition, the Court's
previous ruling in Cassis de Dejon hade made clear, had as its purpose to capture all overtly or
disguisedly, obviously or indirectly protectionist trade rules impeding imports from EU Member
State into another. The distinction in Keck between sales- and product-related rules only made
sense if it could obviate detailed examination of the trade effects of selling regulation on the
grounds that it did not generally have a differential impact on imported and domestic goods.
