The Cornerstone Barristers Information Law team has been involved in some of the most important and high profile cases in the past few years including Professor David Carroll v Cambridge Analytica, Maurizi v Information Commissioner, Cooper v National Crime Agency and Stunt v Associated Newspapers Ltd.

Members provide advice on complex information law and data protection issues to both private and public sector clients, and they regularly appear in the higher courts and tribunals. This ensures that they are always in a position to give swift, practical advice in this highly technical area.

The team has particular expertise in data breaches, profiling, big data and AI, individual rights including access rights, right to rectification and right to be forgotten, environmental information requests and FOI requests.

The junior members also provided advice and assistance to the Department of Culture, Media and Sport on various issues arising in respect of the Data Protection Bill 2018. They were subsequently instructed in matters concerning the Data Protection Act 2018, including assisting with the implementation of changes to the Data Protection Act 2018 that will be necessitated by Brexit.

Members are public law barristers with a wide range of cross-sector expertise. This means that they are able to advise on all aspects of a case, where data protection or information law may only represent one of the issues.

This most often arises in the overlap between planning law and access to environmental information but can also be seen in the cross-over between this area of practice and election law, social care records and housing law issues.

Members of our team also regularly provide comprehensive training to clients in order to assist them in complying with their various obligations under GDPR, FOI, EIR and PECR. In this regard, several members provide expert training on behalf of PDP in both data protection law and freedom of information and they are regular contributors to the Freedom of Information Journal.
