Dinah Rose KC has a broad practice, encompassing public law, competition law, EU law and employment law. 

Her particular areas of interest include human rights and civil liberties, competition damages claims, telecommunications, regulation (acting for both regulators and regulated parties), and discrimination law. 

She has a particular strength in written and oral advocacy, across a range of different legal fields. She has appeared in the Court of Appeal, the Supreme Court and the Court of Justice of the European Union in many of the leading cases of recent years, as well as appearing in Hong Kong, the Cayman Islands and the European Court of Human Rights.

Unusually, Dinah has considerable experience both of leading teams in large scale litigation in a commercial environment, and of representing individuals bringing publicly-funded claims against the State.

Dinah was appointed President of Magdalen College, Oxford and took up office in September 2020. She will be the 43rd President of the College since its foundation in 1458, and the first woman to hold the post.

Some recent highlights of Dinah’s practice have included: 

  • representing Visa Inc in competition damages claims brought by large retailers, currently pending before the Supreme Court
  • representing UNISON in the Supreme Court in its successful challenge to the lawfulness of Employment Tribunal fees, which the Court found to be a breach of the common law right of access to justice (R (UNISON) v Lord Chancellor July 2017)
  • representing the Law Society in its intervention in the Court of Appeal in the case of ENRC v Serious Fraud Office (August 2018), concerning the scope of legal professional privilege;
  • representing the claimant in the Court of Appeal and Court of Final Appeal in Hong Kong in the case of QT v Director of Immigration (July 2018). Both Courts ruled that the Director's refusal to grant dependent spouse's visas to gay married couples was discriminatory and unlawful;

Chambers and Partners 2019 named Dinah as one of its top 25 ‘Stars at the Bar’ and she was also recognised as a Legal 500 2019 Silk of the Year for Employment Law. Dinah is ranked in Chambers UK and Legal 500 in several practice areas. Recent comments include:
