Pro Bono Work

Claire is a long standing member (since 2009) of Justice for Women (JfW): a feminist pro-bono group advocating and campaigning on behalf of women who have experienced prejudicial treatment by the criminal justice system. In particular, JfW represents on appeal women who have received a conviction for murder, having killed following the experience of severe domestic and sexual violence.

JfW has been established for over 20 years and was instructed in the seminal cases of R v Humphreys and R v Ahluwalia.

Recently Claire was heavily involved in the case of R v Stacey Hyde (reported here). Justice for Women achieved the quashing of Ms Hyde’s murder conviction in the Court of Appeal in November 2014, and Ms Hyde was fully acquitted on the basis of self defence at a re-trial before Winchester Crown Court in the spring of 2015, where Claire assisted leading and junior counsel.

Claire has appeared as a representative for JfW on national news (Channel 5 and Sky).
