Profile / Experience

I am a Trainee Solicitor in the Immigration Department at Duncan Lewis, working in the Croydon office under the supervision of Solicitor Claire Ryan and Immigration Director Bernadette Adusei.

I assist with a number of high profile claims for judicial review. I represent clients in cases challenging administrative detention, claims for injunctive relief against removal, and various challenges to the policies of the Secretary of State of the Home Department (SSHD). This includes an appeal under section 40A of the British Nationality Act 1981 against a decision to deprive a person of British citizenship which requires the Tribunal to consider whether the SSHD's discretionary decision to deprive should be exercised differently.

I have experience of working on immigration, nationality and human rights cases that are heard before the Upper Tribunal, High Court and Court of Appeal.

I speak English, Norwegian, Danish, Swedish and Urdu.

Notable Cases

Supreme Court
  • R (Hysaj Ors) v SSHD [2015] EWCA Civ 1195; [2015] WLR (D) 482 - In a case of impersonation where a person had fraudulently made false representations about his own identity and that fraud was material to the grant of naturalisation, the grant of nationality was a nullity.

Court of Appeal
  • FR & Anor (Albania), R (On the Application Of) v Secretary of State for the Home Department [2016] EWCA Civ 605 - The Court of Appeal has given ruling as to the approach that needs to be followed by the Secretary of State in certifying asylum and human rights claims as “clearly unfounded” under section 94(3) of the Nationality, Immigration and Asylum Act 2002. The Court emphasised the need for the Secretary of State to give separate consideration to a claim for asylum, where she decides whether the claim should be refused, and the decision on the issue of certification. Certification is only possible where the claim permits of only one answer before a tribunal and would be bound to fail. On the facts of these cases, the Court quashed the certificates.

  • Hysaj v Secretary of State for the Home Department [2014] EWCA Civ 1633 - The Court of Appeal, having held that the guidance in the Mitchell and Denton cases applied to applications for extensions of time for filing a notice of appeal, dealt with some questions of general importance (public law cases, shortage of funds, litigants in person, the merits).
