Since 1985 Mr Robertson has been commonwealth counsel for Dow Jones Inc. and has defended journalists and editors of the Wall Street Journal, Barrons and the Far Eastern Economic Review in many foreign courts. He represented Jonathan Randall of the Washington Post (with co-counsel Floyd Abrams) in the ICTY case which established privilege for war reporters. One of his greatest successes has been to establish in European law the reporter's right to protect sources in a landmark judgement of the European Court of Human Rights.
After graduating in history and law from Sydney University and postgraduate studies in Oxford as a Rhodes Scholar, Mr Robertson embarked on a long and distinguished career as a trial counsel and human rights advocate. He acted for Salman Rushdie in the Satanic Verses case and for many men accused of IRA terrorism. He prosecuted ex-dictator Hastings Banda in Malawi, was involved in the proceedings against General Pinochet, and was counsel to the international commission of inquiry into arms trafficking to the Medellin Cartel.
Mr Robertson currently sits as a Recorder (part-time judge) in London: he is head of Doughty Street Chambers, a Master of the Middle Temple and Visiting Professor in Human Rights law at London University.
