Britney Spears' new lawyer said the petition "represents a massive legal victory, as well as vindication" from her father
The court approved Britney's request to appoint former federal prosecutor Mathew Rosengart as her new attorney, replacing Samuel Ingham, who was her court-appointed attorney until he resigned days after the last public hearing
The judge overseeing the conservatorship, Brenda Penny, must either appoint a new attorney or give Britney the option of choosing her own.
Britney Spears also lashed out at the state of California, which she accused of allowing her guardianship to continue, despite documenting the "shock" and "trauma" she has suffered
Judge Brenda Penny set the date for June 23, in which Spears will seek to lift her legal guardianship.
