Ben provides concise and practical advice on specialised aspects of constitutional law and international law, and the complex intersection between the two. These range from human rights (including freedom of expression, access to information, consumer protection, education and equality) to economic governance (including anti-corruption, expropriation, public procurement, foreign investment, trade and tax administration).

Ben delivers advice and training on these topics to law firms and other businesses, and also regularly appears in the media (print, online, television and radio), aiming to make the law more accessible to the wider public.
