Dee has been ranked in the legal directories since 2010 as a leading employment barrister. "She has established a reputation as an adviser with a formidable knowledge of discrimination law." Chambers and Partners. "An all-round class act and technically excellent in discrimination and equal pay cases." Legal 500
Dee is a recognised expert in discrimination law. Her practice primarily consists of multi-week trials involving multiple and complex claims. She is instructed by employers, employees and unions. Due to her expertise, she regularly advises NGOs and government agencies on the development of discrimination law and she has delivered judicial training on discrimination law at ERA in Trier funded by the European Commission. She is also Head of Employment within Cloisters.
Over the past 14 years, Dee has acted in matters covering all forms of discrimination in the employment field. She has represented and advised clients in the following sectors:
• Financial services
• Education (including universities)
• Private healthcare
• Local government
She has particular expertise in equal pay having represented both employers and employees in complex equal pay claims since 2006. At the beginning of her practice, she acted as a junior in the public sector equal pay litigation which started in the North of England representing large multiples of female claimants in low paid roles in the NHS. This led to appearing, at appellate level, in some of the defining equal pay cases which arose from the public sector pay disputes such as Bainbridge (no 2). More recently, she has represented private companies in potentially valuable equal pay litigation including the recent wave of claims in the retail sector. She also regularly represents well-paid women in banking and other sectors who are suing their employers for underpayment in relation to contractual and bonus pay.
Alongside equal pay, Dee has particular expertise in age discrimination law. She appeared in the Supreme Court in Seldon, led by Robin Allen QC, which was a ground breaking age discrimination case. Subsequently, she has advised the Equality Commission of Northern Ireland (ECNI) and the Northern Ireland Commissioner for Children and Young People (NICCY) on its response to proposed legislation extending the existing prohibition on age discrimination. In August 2015, she was the keynote speaker at a conference attended by politicians and policy makers in Belfast concerning age discrimination. Dee has also been advising AGE PLATFORM, an NGO, on a proposed European Directive which will extend the prohibition on age discrimination. She is also advising them on the content of a proposed new UN Convention on age discrimination. She drafted the Technical Guidance accompanying the ban on age discrimination in goods, facilities and services on behalf of the Equality and Human Rights Commission in GB alongside colleagues in chambers. In 2018, she gave evidence as an expert witness to the Women and Equalities Committee on older people in the workplace.
Dee has particular interest in the education sector having advised on discrimination issues in the employment field as well as claims in the County Court. In 2014, she advised the Equality and Human Rights Commission on the extent to which gender segregation was permitted within university campuses. She has also advised on the use of retirement ages in an education setting. Dee is also a governor for a school in Twickenham.
Goods, facilities and services including discriminatory tech
Beyond the employment sphere, Dee advises on discrimination issues in the goods, facilities and services space including private clubs. She is also involved in the growing debate concerning the interplay between the Equality Act 2010 and discriminatory technology. She has co-authored two papers in this growing area: "Algorithms, Apps & Artificial Intelligence: The next frontier in discrimination law" (2018) and "Algorithms, Apps & Artificial Intelligence: Can data protection laws be used to challenge discriminatory tech?". She has spoken at DLA on this topic and at the Public Law Project's annual conference in the winter of 2018 on the interplay between discriminatory technology and judicial decision making. Along with Robin Allen QC, she hosts www.ai-lawhub.com which contains information on how service providers can ensure that technology complies with the Equality Act 2010.
