Dinah Rose QC 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.

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.

Some recent highlights of Dinah’s practice have included: 

  • 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 Final Appeal in Hong Kong in the case of QT v Director of  Immigration (July 2018), a judicial review of the Director's refusal to grant dependent spouse's visas to gay married couples. The Court ruled that the policy was discriminatory and unlawful;
  • representing the Law Society in its judicial review of cuts made by the Lord Chancellor to criminal legal aid (R (Law Society) v Lord Chancellor, August 2018). The Divisional Court quashed the Lord Chancellor's decision on the grounds of unfairness and irrationality;
  • representing reproductive rights HGOs in their intervention in the Supreme Court in a challenge to the prohibition in Northern Ireland on abortion in cases of fatal foetal abnormality, rape and incest (Northern Ireland Human Rights Commission v Attorney General for Northern Ireland May 2018);
  • representing Visa Inc in its continuing defence to claims brought by retailers alleging that interchange fees charged on card transactions are anti-competitive, and breach Article 101 TFEU (Sainsbury's v Visa Commercial Court July 2017, Court of Appeal July 2018);
  • Representing 10 civil liberties NGOs in a successful challenge before the European Court of Human Rights to the mass interception of data by the security services under RIPA (September 2018), found by the Court to breach Articles 8 and 10 of the European Convention on Human Rights;
  • Representing IBM in its successful appeal to the Court of Appeal against a judgment overturning IBM's closure of its final salary pension scheme (IBM v Dalgleish, August 2017);
  • representing a journalist from The Guardian in the Supreme Court in his successful challenge under the Freedom of Information Act to the Government’s refusal to disclose letters written by Prince Charles to Government ministers (R (Evans) v Attorney General 2015); 

In Chambers UK 2018 Dinah is ranked as one of its 19 ‘Stars at the Bar’. She has recommendations in eight practice areas.  In three of these practice areas, Dinah is ranked in the ‘Star’ category and she is ranked in the top band for three more areas. She is described as "one of the most formidable human rights and public law law barristers, who is also a stellar performer in employment and competition matters". Chambers quotes sources as saying that she is: “one of the most intellectually fearsome people at the Bar and an advocate with an instinct for the killer point.”, and  “a devastating advocate with an immense knowledge of the law. She gives practical advice, is down to earth, and is easy to get on with.” Chambers states that "her standing at the Bar was best summed up by one commentator, no doubt expressing the views of many, who said: “I can think of no one I would prefer to have on my side.”"



Public & Regulatory

Dinah has a very broad practice across the whole spectrum of public  law. She represents both claimants and defendants in a wide variety of courts and specialist tribunals, from the Administrative Court to the highest appellate levels. She has appeared in many of the leading public law cases of recent years. Dinah’s public law work overlaps with her expertise in human rights and EU law. 

Claimants Dinah has advised and represented range from NGOs and publicly-funded individuals to large commercial entities and trade associations challenging regulatory or Government decisions and legislation. Dinah has also represented JUSTICE, Liberty, and other public interest groups in appellate interventions.

On the Defendant side, Dinah has advised and represented many public authorities, including Government departments, the NHS, local authorities, and a wide variety of regulators, including Ofcom, Ofgem, the Human Fertilisation and Embryology Authority, the GMC and other medical regulators, the Independent Police Complaints Commission, the Advertising Standards Authority, The Teaching Standards Council, the Bar Council and the Law Society.

EU & Competition

Dinah’s interest in competition law developed from her expertise in regulatory matters, through cases such as the Pay TV appeal. Over the past decade she has acquired a strong reputation in this field, including both European and domestic regulatory investigations, and stand alone and follow-on damages actions. She is currently instructed in some of the largest competition investigations and private litigation, including the Commission’s investigation into alleged Euribor fixing, and claims for damages brought against Visa. Dinah has appeared before the Commission in Brussels, and has extensive experience of appeals before the Competition Appeal Tribunal, and claims in the Commercial Court, where she has acted for both claimants and defendants.

Dinah has longstanding expertise in EU law, and has appeared in the CJEU on many occasions. Her practice covers a very wide range, including social policy (discrimination and employment rights, free movement of workers, social security), competition, environmental law, sanctions (Iranian and Ukrainian), and other forms of regulation, including taxation and tobacco regulation.
