Update 11 December 2018 leave to appeal applied for.
Warby J in  EWHC 2599 (QB) Lloyd v Google (a class action suit with third party financing) considers, and rejects, jurisdiction against Google Inc (domiciled in the US) following careful consideration (and distinction) of the Vidal Hall (‘Safari users) precedent.
Of note is that the jurisdictional gateway used is the one in tort, which requires among others an indication of damage. In Vidal Hall, Warby J emphasises, that damage consisted of specific material loss or emotional harm which claimants had detailed in confidential court findings (all related to Google’s former Safari turnaround, which enabled Google to set the DoubleClick Ad cookie on a device, without the user’s knowledge or consent, immediately, whenever the user visited a website that contained DoubleClick Ad content.
In essence, Warby J suggests that both EU law (reference is made to CJEU precedent under Directive 90/314) and national law tends to suggest that “damage” has been extended in various contexts to cover “non-material damage” but only on the proviso that “genuine quantifiable damage has occurred”.
Wrapping up, at 74: “Not everything that happens to a person without their prior consent causes significant or any distress. Not all such events are even objectionable, or unwelcome. Some people enjoy a surprise party. Not everybody objects to every non-consensual disclosure or use of private information about them. Lasting relationships can be formed on the basis of contact first made via a phone number disclosed by a mutual friend, without asking first. Some are quite happy to have their personal information collected online, and to receive advertising or marketing or other information as a result. Others are indifferent. Neither category suffers from “loss of control” in the same way as someone who objects to such use of their information, and neither in my judgment suffers any, or any material, diminution in the value of their right to control the use of their information. Both classes would have consented if asked. In short, the question of whether or not damage has been sustained by an individual as a result of the non-consensual use of personal data about them must depend on the facts of the case. The bare facts pleaded in this case, which are in no way individualised, do not in my judgment assert any case of harm to the value of any claimant’s right of autonomy that amounts to “damage”…”
The judgment does not mean that misuse of personal data cannot be disciplined under data protection laws (typically: by the data protection authorities) or other relevant national courses of action. But where it entails a non-EU domiciled party, and the jurisdictional gateway of ‘tort’ is to be followed, ‘damage’ has to be shown.
