A civil claim for damages against Harry Dunn’s alleged killer will remain in the US due to her “refusal” to return to the UK, a judge has ruled.
Mr Dunn, 19, died in a crash near RAF Croughton in Northamptonshire in 2019.
The suspect Anne Sacoolas returned to the US, claiming diplomatic immunity, and an extradition request was blocked.
Mrs Sacoolas, 43, had applied to dismiss the case on the grounds it should be heard in the UK.
The move came despite her legal team admitting she would not agree to face trial due to a “concern” she would not “receive fair treatment”.
Mrs Sacoolas has been charged with causing the teenager’s death by dangerous driving but an extradition request was rejected by the US government in January last year.
A court hearing in the eastern district of Virginia had previously been told her work in intelligence was “especially a factor” in her departure and that she “fled” the UK for “issues of security”.
But judge Thomas Ellis said: “While it is commendable that defendant Anne Sacoolas admits that she was negligent and that her negligence caused Harry Dunn’s death, this does not equate acceptance of responsibility.
“Full acceptance of responsibility entails facing those harmed by her negligence and taking responsibility for her acts where they occurred, in the United Kingdom.”
The judge said he also took into account the “firm support” of Foreign Secretary Dominic Raab, who submitted a letter to the court which read: “I strongly support [the Dunn family’s] right to bring the case.
“It is of course for the US courts to decide the issue of venue but for our part, the British government takes the view that British citizens can bring their case in whichever court they think appropriate.”
Due to her “refusal” to return to the UK, the Dunn family said they brought a civil claim for damages against her as “a last resort”.
Mr Dunn’s mother Charlotte Charles said: “We are pleased and relieved at the court’s decision.
“We only took this step as a last resort following the denial of justice in the extradition case on strong advice from our legal team.”
Other motions Sacoolas’s legal team submitted to dismiss the case will be heard on 3 March in Virginia.
