Foreign Secretary Dominic Raab wrote to Mr Dunn's family on Saturday to explain both the British and US governments now considered Mrs Sacoolas' immunity irrelevant.
The letter said: "We have pressed strongly for a waiver of immunity, so that justice can be done... Whilst the US government has steadfastly declined to give that waiver, that is not the end of the matter.
"We have looked at this very carefully... the UK government's position is that immunity, and therefore any question of waiver, is no longer relevant in Mrs Sacoolas's case, because she has returned home.
"The US have now informed us that they too consider that immunity is no longer pertinent."
Mark Stephens, a lawyer for the Dunn family said: "She was allowed to, or encouraged to be spirited away on an American transport plane and effectively rendered a fugitive from British justice.
"And now of course we find out that she's not entitled to diplomatic immunity, and in those circumstances she is in a foreign land a fugitive from British justice.
"We do hope she returns herself voluntarily and that this was just a bad piece of advice she received from the American authorities."

We look forward to this fugitive being returned to the UK swiftly to face legal proceedings and justice.
