Geoffrey Ronald Robertson AO, KC (born 30 September 1946)[2] is an Australian-British barrister, academic, author and broadcaster.

[3] He serves as a Master of the Bench at the Middle Temple, a recorder, and visiting professor at Queen Mary University of London.

[6] His father, Frank, who would go on to be a senior officer of the Commonwealth Bank, and later a stockbroker,[7] survived an RAAF training flight crash in Chiltern, Victoria, in 1943.

[15] In 1989 and 1990 he led the defence team for Rick Gibson, a Canadian artist, and Peter Sylveire, a director of an art gallery, who were charged with outraging public decency for exhibiting earrings made from human foetuses.

[25] In December 2002 Robertson was retained by The Washington Post to represent its veteran war correspondent, Jonathan Randal, in The Hague at the United Nations Court, the International Criminal Tribunal for the former Yugoslavia.

The case centred on an article published in the WSJ in 2002, which alleged that the United States were monitoring the bank accounts of a Saudi Arabian businessman to ensure he was not funding terrorists.

[27] In early 2007, instructed by the Indigenous lawyer Michael Mansell, Robertson took proceedings for the Aboriginal Tasmanians to recover 15 sets of their stolen ancestral remains, then being held in the basement of the Natural History Museum in London.

He was also involved in the controversial inquest of Helen Smith and also in the Blom-Cooper Commission inquiry into the smuggling of guns from Israel through Antigua to Colombia.

[15] Robertson has been on several human rights missions on behalf of Amnesty International, such as to Mozambique, Venda, Czechoslovakia, Malawi, Vietnam and South Africa.

[32] On 28 January 2015 he represented Armenia with barrister Amal Clooney at the European Court of Human Rights (ECHR) in the Perinçek v. Switzerland case.

[2][40] These shows invite notable people, often including former and current political leaders, to discuss contemporary issues by assuming imagined identities in hypothetical situations.

[48] This, Robertson believes, constitutes the crime of assisting underage sex and when he was still Cardinal Ratzinger, the retired pope approved this policy up to November 2002.

(2014) Robertson presents an argument based on fact, evidence and his knowledge of international law, claiming that the horrific events that occurred in 1915 constitute genocide.

[50] They had met in 1988 during the filming of an episode of Hypothetical for ABC Television; Robertson was dating Nigella Lawson at the time and Lette was married to Kim Williams.
