On 7 March 2019 Lady Brenda Hale delivered the 2019 Cambridge Freshfields Lecture entitled "Principle and Pragmatism in developing Private Law". Lady Hale is the current President of the Supreme Court of the United Kingdom, and non-permanent judge of the Court of Final Appeal of Hong Kong. In the lecture, Lady Hale gave her perspective on whether the development of the law should be guided by doctrine, or policy. She did this through a reflection and analysis of a number cases, including many on which she had presided, including Patel v Mirza and Radmacher v Granatino. The Cambridge Freshfields Lecture is an annual address delivered by a guest of the Cambridge Private Law Centre (CPLC), and the event is sponsored by Freshfields Bruckhaus Deringer. More information about this lecture, including photographs from the event, is available from the Private Law Centre website: http://www.privatelaw.law.cam.ac.uk/events/past-events
