Judge Brenda Penny told the court the arrangement has which had traumatised and exploited Britney should be terminated immediately.
As the news filtered out to hundreds of her #FreeBritney fans rallying outside in the street there were cheers and ticker tape explosions of joy.
Britney's lawyer, Matthew Rosengart, told the crowd that the fight for the truth about what had happened to Britney would go on, and he pressed for her father, Jamie Spears and the singer's former management, Tri Star, to be investigated for financial mismanagement.
For the dedicated fans who have propelled her case to international recognition it was a moment they had waited so long to savour.
Britney herself posted her reaction on twitter and instagram, saying 'I love my fans so much...I think I'm gonna cry the rest of the day' with the hashtag #freedbritney.
What happens next in her case depends on the star's appetite for yet more legal battles. But what is not in doubt is that the whole conservatorship system - which controls the lives of around 1.3 million Americans - faces more scrutiny and reform.
