Shamima Begum lost her appeal against the decision to strip her of her British citizenship, despite having a strong case for being a victim of trafficking.
Her appeal had been completely rejected, Mr. Justice Jay informed the court that was handling her case in a semi-secret setting.
The 23-year-old is now stuck in a camp in northern Syria and is no longer allowed to travel back to the UK as a result of the ruling.
Ms. Begum traveled to join the so-called Islamic State organization in 2015 at the age of 15.
She later got married to a fighter from the gang and had three children, all of whom have passed away.
She was held as an IS supporter in a camp in 2019 after the then-home secretary Sajid Javid revoked her of her British passport, preventing her from returning home.
Even though Ms. Begum’s attorneys made compelling claims that she was a victim, the Extraordinary Immigration Appeals Commission determined that the decision, made after ministers received national security advice about her threat to the UK, had been lawful.
