Profile / Experience

I am a Supervisor/Solicitor within the Public Law and Immigration Departments at Duncan Lewis, having joined in October 2018. I have more than 10 years’ experience in public law challenges, judicial review claimant matters, human rights, asylum, deportation, challenging immigration, nationality, EU Law and point based systems.

I first began providing immigration advice in early 2008 at the Immigration Advisory Services (IAS), where I dealt with a wide variety of cases across the full spectrum of immigration, nationality and asylum law and frequently conducted appeals advocacy before the First Tier and Upper Tier of the Immigration Asylum Chamber.

Whilst employed at LUPINS I developed my expertise in public law under the supervision of solicitor and now fellow Duncan Lewis colleague Stefan Vnuk. I successfully represented clients in false imprisonment/unlawful detention claims in the County Court, age assessment challenges, the procedures of asylum claims under the Detained Fast Track (DFT) system and Detained Asylum Casework (DAC). I also challenged the decisions of the competent authority. I have successfully challenged immigration decisions to remove an individual to third countries under the Dublin II and III Regulations (Articles 9, 17, 27, 28). In addition to Immigration Tribunal matters, I have extensive experience in representing clients at the Court of Appeal, High Court and in family law proceedings.

I am an accredited Level 2 Senior Caseworker under the Law Society's Immigration and Accreditation Scheme which means I have specialist knowledge and experience in the area of Immigration law and can represent both publicly (legal aid) and privately funded clients.

I am in the process of cross qualifying as a Lawyer under Canadian Law. This will enable me to work as an international lawyer. I also volunteer with numerous charities that help the less privileged. I previously worked for the British Red Cross and was responsible for educating children at schools in Reading during key historical events such as Black History Month and World refugee day. I am still part of the British Red Cross and conduct work on a voluntary basis.


  • LLM (International Humanitarian Law)- distinction
  • I was granted funding to further my academic experience. My PHD proposal was based on the accountability of peacekeepers under international humanitarian law.

Notable Cases

Court of Appeal
  • Secretary of State for the Home Department v HM Court of Appeal Civil Division [2016] EWCA Civ 565 - It was concluded that the Competent Authority which deals with human trafficking did not breach procedural obligations of Article 4 of the ECHR. The instructed barristers, Martin Westgate QC and Ms Keelin McCarthy and I were granted funding this point of law at the Supreme Courts. Grounds were prepared to challenging this decision to the Court of Appeal however we had to withdraw as the Claimant was missing after the Home Office released him to the alleged traffickers.

High Court
  • Minh (Reg on the Application) v SSHD [2015] EWHC 1725 - The case was about the proper operation of the procedures for determining whether a procedures for determining whether a person may be a victim of trafficking. It was decided the Court’s role is not determine for itself whether there were or not such reasonable grounds, but to decide whether the decision makers properly addressed himself to the right legal issue.

Civil Court
  • R v (on the application of Salah Ali Eisa) v SSHD [2017] UKUT 261 - This was a case addressing Articles 17 and 27 of the Dublin Convention 111. It was considered that judicial review is a remedy of sufficient flexibility to comply with Article 27 (1) of the Regulation 604/2013. Since an applicant is allowed to remain while this review is being dealt with, there is a suspension of the 6 months within which transfer must be effected in accordance with Article 27 (3) of Dublin 111. It was also concluded that Article 17 forms an integral part of the Dublin Regulations and should be applied in a manner which furthers the aims of the objectives of the Regulation.
