Practice Areas

Ben is an expert in international criminal and humanitarian law, extradition, business crime, public law, international human rights law and capacity building. He has played key roles in several high-profile international criminal cases over the past decade.

Ben regularly acts in complex extradition proceedings, representing both individuals and requesting states at all levels before the English courts. He also advises on a wide range of extradition-adjacent matters, such as INTERPOL, transfer of sentence, withdrawal of requests following successful challenge, and import extradition.

He advises multinational corporations and prosecuting authorities on investigations, including sanctions and cross-border corruption.

As a result of his background in global investigations and fast-paced international litigation, Ben recognises the value in taking a collaborative approach in complex, document-heavy cases. He has operated in adversarial and inquisitorial systems and, similarly, has experience before tribunals that adhere to both the civil and common law traditions. Ultimately, Ben’s broad international practice ensures that he remains a versatile advocate, both orally and on paper.
