Sadakat Kadri spent a decade as a full-time practitioner at Doughty Street, specialising in criminal, constitutional and international law. He has considerable experience as a Crown Court advocate and has represented appellants at all levels of the UK judicial system, including several death row prisoners before the Privy Council. On the international plane, he has advised governments and citizens on matters ranging from internet regulation to the constitutionality of a coup d'état, and he has participated in appeals in Brunei, Malawi and Fiji. He is also familiar with US legal systems, having studied at Harvard and qualified for the New York Bar, and he has.worked at the American Civil Liberties Union and acted for a number of US clients.

Sadakat became an associate tenant in order to concentrate on his writing. He regularly contributes to various publications including the London Review of Books, and he is the author of two law-related works: The Trial: A History from Socrates to O.J. Simpson (HarperCollins UK and Random House US) and Heaven on Earth: A Journey Through Shari'a Law (Random House UK and Farrar Straus & Giroux US). He has spoken about both books at academic institutions and literary festivals in many parts of the world.

Sadakat combines his legal and literary interests in work he does for international human rights organisations. He has observed court proceedings in the Middle East on behalf of the Geneva-based International Parliamentary Union, and he went to Syria in March 2011 as part of a delegation of the International Bar Association's Human Rights Institute (IBAHRI). The report that he helped write, which formed the basis for Syria's suspension from the International Bar Association in the summer of 2012, is viewable through this link. In August 2012, he travelled to Myanmar (Burma) as the rapporteur on IBAHRI's first ever mission to that country. The report he compiled, officially launched at the Law Society in January 2013, can be found online here.
