Stephanie was leading Counsel for the lead claimant, Medical Justice, and two individual claimants in a test case challenging the adoption by the Secretary of State of a more restrictive definition of torture in her new Adults at Risk statutory guidance issued under s. 59 Immigration Act 2016. As a result of this challenge, the Secretary of State was ordered to reissue guidance that protects torture victims from harm in detention.

B (Algeria)(Respondent) v SSHD [2018]
Stephanie was leading Counsel for the respondent in this major Supreme Court judgment which considered the correct approach to the availability of immigration bail when detention powers, in line with the Hardial Singh principles, are exhausted. Originally considered within SIAC, this case had a national security context. The Supreme Court unanimously dismissed the SSHD’s appeal.

VC v Home Secretary [2018]
Stephanie was leading Counsel in this test case concerning whether the Home Secretary had acted unlawfully and in breach of the Human Rights Act when she detained a severely mentally disordered offender who lacked mental capacity to take steps to challenge the legality of his detention. The case concerned whether the Home Secretary breached Article 3 ECHR, the Equality Act and her own detention policy. The case was successful in the Court of Appeal.

AM (Afghanistan) v SSHD [2017]
Widely reported guideline case in which Stephanie appeared as leading Counsel. The Court of Appeal provided guidance on the correct approach to be followed by all Tribunals determining asylum claims made by unaccompanied children and other vulnerable asylum seekers. The case was also very important in creating a right to a litigation friend in the Tribunals.

R (AJS and AJU) [2018]
Stephanie appeared as leading Counsel representing a detained father (AJS) and his daughter in their linked judicial review and civil damages challenges. The case was successful and father and daughter were reunited. The Home Office accepted that AJS was unlawfully detained for the entirety of his detention. There were multiple breaches of the Home Office’s published policy relating to Detention and Family Separation and they agreed to pay the Claimants £50,000 in damages.

MA v SSHD [2018]
This case concerned a highly vulnerable victim of torture with serious mental ill health who was subject to repeated physical and mental ill treatment, including derogatory abuse by G4S guards at Brook House IRC, recorded in footage broadcast on the BBC’s Panorama programme in September 2017. Stephanie appeared as leading Counsel and secured permission to seek an independent public inquiry into the evidence of systematic abuse that was taking place at the Immigration Removal centre.

Hussein & Ors v SSHD & G4S (Liberty intervening) [2018]
In this high-profile challenge, the Court held that the Secretary of State had interfered with and indirectly discriminated against the rights of Muslims protected under human rights and Equality Act 2010 duties, to properly observe their faith through prayer owing to the conditions of the Brook House detention centre, to include being forced to pray next to dirty, recently used, open toilet pans, in crowded rooms, while locked in overnight.

UK Oil & Gas Investments PLC & Ors v Persons Unknown & Ors [2018]
Stephanie appeared as lead Counsel for environmental campaigners Weald Action Group and Friends of the Earth in this high-profile challenge seeking to overturn a broad injunction being sought by UK Oil and Gas against “persons unknown”, prohibiting lawful acts of protest against fracking activities.

VC v Home Secretary [2018]
Stephanie was leading Counsel in this test case concerning whether the Home Secretary had acted unlawfully and in breach of the Human Rights Act when she detained a severely mentally disordered offender who lacked mental capacity to take steps to challenge the legality of his detention. The case concerned whether the Home Secretary breached Article 3 ECHR, the Equality Act and her own detention policy. The case was successful in the Court of Appeal.

R (Medical Justice and 7 Ors) v Secretary of State for the Home Department [2017]
Stephanie was leading Counsel for the lead claimant, Medical Justice, and two individual claimants in a test case challenging the adoption by the Secretary of State of a more restrictive definition of torture in her new Adults at Risk statutory guidance issued under s. 59 Immigration Act 2016. As a result of this challenge, the Secretary of State was ordered to reissue guidance that protects torture victims from harm in detention.

B (Algeria)(Respondent) v SSHD [2018]
Stephanie successfully represented the respondent, B, in his challenge against the Home Office/Special Immigration Appeals Commission (SIAC) and conflict with Article 5 ECHR. The Supreme Court rejected the Home Secretary’s argument that strict conditions of bail under Schedule 2 of the Immigration Act 1971 could be imposed indefinitely. This case led to a major ruling on powers to restrict the liberty and freedoms of those who cannot lawfully be detained.

MS v SSHD [2017]
Stephanie acted as leading counsel in this case challenging the limitations and conditions to the claimant’s civil liberties of the SSHD’s Restricted Leave Policy. The claimant, a Sikh Indian national who had resided in the UK for 20 years with his British family, had been refused indefinite leave due to his historical links to terrorist activities in India. He was not entitled to protection from the Refugee Convention; however, he could not be removed because to do so would breach his human rights due to the real risk of persecution. The court held that the restricted leave conditions restricted MS’s liberty to live his life, there was no need for the conditions and it was irrational not to grant indefinite leave. A residence condition was ultra-vires of the powers under the 1971 Act.
