I am a Consultant Partner in Lewis Silkin’s Employment, Immigration and Reward division based in Belfast.
I advise on all aspects of employment law and public administrative law in Northern Ireland.
I have considerable experience of advising clients on all manner of employment issues including disciplinary and grievances, change management, discrimination, protection from harassment, employment related litigation, industrial relations and TUPE and represent both employers and employees in Employment Tribunal claims.
I have a wide client base ranging from public sector employers, financial institutions, manufacturing businesses, small and medium sized employers through to individual employees. I provide advice and representation which is geared towards resolution of issues where possible but also robust representation when required.
Public and administrative law
My public administrative law experience and practice involves advising and representing public authorities and individuals in judicial review matters, managing public money, good governance and the avoidance of maladministration. My judicial review experience includes representing a group of applicants including politicians and members of the NI Assembly, human rights activists and human rights organisations in the Supreme Court in the successful Brexit challenge to the triggering of Article 50 without Parliamentary approval.
I also regularly provide advice on Data Protection and Freedom of Information.
I have been ranked as a leader in my field by Chambers and Partners UK and described as “an expert in human rights and anti-discrimination law. Her international reputation has led to her advising on fair employment policy in both the UK and the USA”.
I am a member of the Employment Lawyers Group and the Tribunal Rules Committee.
