Litigation lawyers say data protection class actions have been dealt a significant blow by the Lloyd v Google judgment, which was handed down by London’s Supreme court on Wednesday.

A group action to hold Google accountable for £3 billion in compensation for breaching its duties to four million Apple users was dismissed by the Supreme Court, which said consumer rights activist Richard Lloyd failed to show that any individual affected suffered material damage or mental distress as a result of such unlawful processing of personal data.
