Andrew Eaton is the best senior associate in the industry, by a considerable margin. He is calm, deep-thinking and wise.

Legal 500, 2023, Public and Administrative Law

Andrew gets government. He advises clients on the interaction between business, law and policy, with a particular focus on constitutional and administrative law, public sector governance and accountability, and judicial review.  His experience spans multiple industry sectors, typically those that are highly regulated, and includes advising public bodies and the UK Government itself. 

Andrew has been heavily involved in the firm's Constitutional Change taskforce.  This has led to Andrew assisting many businesses around the world to navigate the legal and policy uncertainty brought about by Brexit and, more recently, COVID-19.

Andrew advises on a range of topics, including UK constitutional and administrative law, commercial judicial review, commercial human rights, public international law, political law compliance and freedom of information.  In many cases, his work is done outside the courtroom, helping private sector clients to capitalise on opportunities and mitigate risks through their engagement with government decision-makers. He also helps public sector clients to make more robust policy decisions, at various stages throughout the policy development and implementation life cycle and often in strategically significant contexts. When necessary to achieve his clients' objectives, Andrew acts for claimants, defendants and interested parties in high-profile and complex judicial review and other statutory appeal proceedings.

Andrew is passionate about spreading understanding of the rule of law and how government in the UK really works.  He has given numerous speeches on the legal and policy aspects of Brexit, to a range of audiences, as well as authoring a range of articles, reports, blogs and videos on this and other subjects.  You can find his latest publications on HL Engage.
