• Article 4(1)(a) of Directive 95/46/EC plays an important role in determining the applicability of EU data privacy law. However, its wording lends itself to various interpretations.• Consequently, it is unsurprising that Article 4(1)(a) has been the object of several recent CJEU judgments, and that this provision is the object of ongoing litigation.• This article seeks to analyse and predict the future landscape by examining the two relevant recent CJEU decisions (the Google Spain case and the Weltimmo case), Advocate General Saugmandsgaard Oe’s Opinion in Verein fur Konsumenteninformation, and in particular the currently ongoing Facebook Fanpages dispute.

欧盟数据隐私法第 4(1)(a) 条“控制者的建立”——是时候控制这个不断扩大的概念了吗？

• 95/46/EC 指令第 4(1)(a) 条在确定欧盟数据隐私法的适用性方面发挥着重要作用。然而，它的措辞有多种解释。• 因此，第 4(1)(a) 条成为欧洲法院最近几项判决的对象，并且该条款是正在进行的诉讼的对象也就不足为奇了。• 本文寻求通过审查最近两个相关的欧洲法院裁决（Google 西班牙案和 Weltimmo 案）、总检察长 Saugmandsgaard Oe 在 Verein fur Konsumenteninformation 中的意见，特别是目前正在进行的 Facebook Fanpages 争议，来分析和预测未来前景。
