Jagoda is an in-demand junior who practices across the range of chambers’ practice areas. She has been named as a “Rising Star” in administrative law and human rights, and in civil fraud, by Legal 500. She is currently shortlisted for Advocate of the Year (jointly with Jennifer MacLeod) at the Women in Law and Diversity Awards 2026 (for her work on the Sparman Inquest).

She is regularly instructed on high profile cases in public, commercial and competition law for claimants and defendants. She has appeared in cases listed in in the Lawyer’s Top 20 cases three years in a row (appearing as sole counsel in interim hearings in two of those cases), and last year was also named in the Lawyer’s Top 20 appeals. Notable instructions include:

  • Public law: Al Haq v Secretary of State for Business and Trade [2025] EWHC 173 (Admin) and [2025] EWCA Civ 1433: appearing for the Claimant in a judicial review challenge to the export of F-35 fighter jet parts to Israel following the military invasion of Gaza after 7 October 2023 (led by Phillippa Kaufmann KC, Raza Husain KC and Blinne Ní Ghrálaigh KC) (one of the Lawyer’s Top 20 cases for 2025). Jagoda appeared unled at an interim hearing regarding disclosure.
  • Commercial law: JSC Commercial Bank Privatbank v Kolomoisky and others [2025] EWHC 1987 (Ch) in which the High Court found a $1.9 billion fraud to have been perpetrated against Privatbank, Ukraine’s largest lending bank, by its former owners, after a 14 -week trial at which Jagoda appeared for the First Defendant (led by Mark Howard KC, Mike Bools KC, Alec Haydon KC and Alex Milner KC). Jagoda also acted as sole counsel at the first consequentials hearing.
  • Competition law: Merchant Interchange Fee Umbrella Proceedings: Jagoda acts for Mastercard in these mass proceedings concerning interchange fees, in which the next step will be a 10 week trial concerning exemption under Article 101(3) TFEU (led by Mark Hoskins KC and Matthew Cook KC)

Jagoda is equally comfortable led in a team of counsel on large, significant matters, and acting as sole counsel – she has appeared as sole counsel in the Administrative Court, the Insolvency and Companies Court, the Business and Property Courts, county courts and various tribunals.

She is also committed to a pro bono practice: she has appeared on the Pro Bono Recognition List every year since its inception and was shortlisted for Young Barrister of the Year at the Bar Pro Bono Awards 2024.
