Senior Associate Solicitor, Public Law and Human Rights
Sarah joined Simpson Millar in 2017 and has more than ten years’ experience in the legal profession.
As a member of our Public Law team, she works across a range of areas, with the bulk of her practice being judicial review and associated claims under the Human Rights Act 1998.
Sarah specialises in bringing challenges against central and local government on behalf of vulnerable individuals, and she has a particular interest in representing children and victims of trafficking. She regularly acts for young people who have been exploited by county lines gangs. She has extensive experience in bringing judicial reviews challenging NRM trafficking decisions, unlawful detention, child refugee family reunion refusals, and local authority decisions to deny support or accommodation to children in need and care leavers.
In addition to public law challenges, Sarah advises in private law actions against public bodies for false imprisonment, personal injury, and Human Rights Act damages claims, many of which follow on from a successful judicial review claim.
Sarah received a BA degree in Philosophy and Theology from Oxford University in 2010, following which she studied Law at the University of Law, earning the LLB qualification in 2013. She then completed her training contract at Linklaters LLP, qualifying into their Litigation department in 2015. Before joining the Public Law team at Simpson Millar, she worked in the Housing department of the Mary Ward Legal Centre, mainly representing vulnerable clients in housing possession cases.
Sarah has carried out pro bono work for several organisations including Bail for Immigration Detainees, the Centre for Criminal Appeals, Amicus, and the Centre for Reproductive Rights.
"Throughout the case Sarah was proactive, her advice was clear and sensible, she kept me informed throughout and she clearly made efforts to obtain the best possible outcome for a client who was, at times, challenging. I very much hope to work with her again. "

Cases Dealt With
HNH v Secretary of State for the Home Department; multiple cases
Sarah acted for HNH in several linked cases against SSHD, beginning with simultaneous judicial reviews of the decisions to (i) detain HNH in Yarl’s Wood Immigration Removal Centre in 2020; and (ii) find that HNH was not a victim of trafficking under the Modern Slavery Act 2015. Both cases were successful, and HNH was released from detention and formally recognised by SSHD as a victim of trafficking and modern slavery for the purpose of sexual and criminal exploitation. Sarah then brought a civil claim for damages for personal injury, false imprisonment and breaches of Articles 4 and 5 of the Human Rights Act 1998, ultimately securing a significant payment of damages from SSHD.
