Felicity McMahon


Felicity acts and advises all aspects of Chambers’ practice, both Claimant and Defendant work, including: defamation, privacy and confidence, data protection, copyright, access to journalistic material, contempt, harassment, injunctive relief and sports law. Her work often includes consideration of the balance between Articles 8 and 10 of the European Convention on Human Rights.

She has particular experience of advising on data protection issues including: advising organisations on their obligations in relation to the data they hold and how and when they are permitted to use that data including for marketing purposes, advising individuals on how they can seek access to data held about them and how to seek its removal or rectification, and the emerging so-called “right to be forgotten”. Felicity advises on these issues both in relation to the current law and in terms of preparing for the implementation of the General Data Protection Regulation (GDPR).

Felicity also takes a keen interest in issues relating to online publication, social media and user-generated content.
