C-191/15 Verein für Konsumenteninformation v Amazon SarL is one of those spaghetti bowl cases, with plenty of secondary law having a say on the outcome. In the EU purchasing from Amazon (on whichever of its extensions) generally implies contracting with the Luxembourg company (Amazon EU) and agreeing to Luxembourg law as applicable law. Amazon has no registered office or establishment in Austria. VKI is a consumer organisation which acted on behalf of Austrian consumers, seeking an injunction prohibiting terms in Amazon’s GTCs (general terms and conditions), specifically those which did not comply with Austrian data protection law and which identified Luxembourg law as applicable law.
Rather than untangle the bowl for you here myself, I am happy to refer to masterchef Lorna Woods who can take you through the Court’s decision (with plenty of reference to Saugmandsgaard Øe’s Opinion of early June). After readers have consulted Lorna’s piece, let me point out that digital economy and applicable EU law is fast becoming a quagmire. Those among you who read Dutch can read a piece of mine on it here. Depending on whether one deals with customs legislation, data protection, or intellectual property, different triggers apply. And even in a pure data protection context, as prof Woods points out, there now seems to be a different trigger depending on whether one looks intra-EU (Weltimmo; Amazon) or extra-EU (Google Spain).
The divide between the many issues addressed by the Advocate General and the more narrow analysis by the CJEU, undoubtedly indeed announces further referral.
