Position

Jacob is a barrister specialising in commercial litigation and arbitration. He has advised individuals, corporates and sovereigns, including Argentina, Greece, Iraq, Venezuela and the UK. His practice areas include finance, civil fraud, business and human rights, aviation and technology.

Jacob has a particular focus on data and AI. He is the author of a widely-cited book ‘Robot Rules: Regulating Artificial Intelligence’ and has acted in several groundbreaking disputes in that field.

His recent work includes acting in the ‘AI Inventor’ case, in which the Supreme Court considered whether an invention devised by an AI program can be registered as a patent. Jacob was instructed by a group of banks in a (now settled) multi-billion-dollar case where the claimants had sought, for the first time in a civil claim, to rely on evidence generated by AI. Jacob acted in a claim brought by Uber and Ola Cabs drivers, successfully challenging the use of algorithmic decision-making to fine the drivers and terminate their contracts. As sole counsel Jacob also successfully defended the first company to be investigated by the ICO for alleged algorithmic bias.

Jacob is a former solicitor-advocate, having qualified in 2014. He has acted as sole counsel in the High Court, an LCIA Arbitration and the Court of Appeal and as junior counsel in the UK Supreme Court and the ICSID Tribunal in Washington DC. He is on the Attorney-General’s Panel of Counsel.

He has been described by clients as “phenomenal” and “an outstanding up-and-coming barrister”.
