    Work spans disputes and transactions governed by treaties and conventions, state and diplomatic immunity, extradition and mutual legal assistance, international criminal and humanitarian matters, sanctions compliance and cross-border enforcement of judgments. Solicitors draft and negotiate bilateral and multilateral agreements and dispute-resolution clauses, advise on the State Immunity Act 1978 and the Extradition Act 2003, make or resist extradition or mutual legal assistance applications in the domestic courts, represent clients on jurisdiction and enforcement issues and liaise with the Foreign, Commonwealth & Development Office, regulators and foreign counsel.
