Jamie Spears remains Britney's co-conservator

Britney Spears' dad is to remain the troubled singer's co-conservator after a California Court of Appeal judge on Monday threw out a plea by an attorney on her behalf to challenge Jamie Spears' co-conservatorship.

Attorney Jon Eardley, who claimed to represent the Toxic singer, filed an appeal March 11 claiming that Britney's civil rights were being violated because she was being held against her will by her father.

But justice Roger Boren wrote in a ruling that the court has no jurisdiction to grant an appeal, according to the Associated Press.

Jamie's co-conservatorship over Britney was recently extended until July 31.

Jamie Spears has been looking after his daughter's assets since February 4 this year, when she was admitted to a psychiatric facility for the second time.

LA Superior Court Commissioner Reva Goetz named Jamie Spears and Andrew Wallet temporary co-conservators, giving them the right to employ bodyguards, restrict Britney's visitors and approve her contracts.

Britney, 26, discharged herself from the UCLA Medical Center in Los Angeles on February 6 after doctors ruled she did not pose a danger to herself or to others.
