Formerly junior Treasury Counsel, Clare has also been concerned in a wide range of public law challenges in connection with the criminal justice system.

She has had extensive experience in extradition and international mutual legal assistance, representing both governments and individuals. She represented Augusto Pinochet in the House of Lords, and led the challenge to the mutual assistance requests made in connection with Silvio Berlusconi’s business activities. She is a co-author (with fellow Matrix member Julian Knowles) of The Law of Extradition and Mutual Assistance (published by Cameron May, 2002).

Since taking silk in 1996, Clare has also been asked to use her skills as a trial advocate in a number of complex civil disputes, most notably the Bermuda Fire & Marine litigation, and the trial of the case of Three Rivers misfeasance action brought in connection with the collapse of BCCI against the Bank of England.

Clare has also developed a substantial and varied appellate practice. She represented Sally Clark when Clark was finally cleared of murdering her two sons by the Court of Appeal in 2003 and Sion Jenkins, the Deputy head teacher who won a retrial in connection with the death of his foster daughter in 2004.
