A court says Britney Spears' father will have permanent control over her finances and career.

Britney Spears' father will maintain indefinite control of her personal and financial affairs after a court commissioner on Tuesday extended the conservatorship that's already in place beyond 2008.

The conservatorship, which had been set to expire December 31, also allows the people controlling Spears' affairs -- a group that includes father Jamie Spears and several attorneys -- some say in her professional career.

• Surprisingly, Britney has approved the ruling. The details have been explained to the 26-year-old and she agreed not to oppose it.

• Spears could petition the court at a later date to have the conservatorship removed, but the court's order otherwise constitutes a lifetime arrangement.

• Los Angeles Superior Court Commissioner Reva Goetz says she granted the permanent conservatorship because Britney Spears has shown she is "susceptible to undue influence" and that making the ruling permanent was "necessary and appropriate."

The ruling came after a lengthy closed door meeting, and followed a recent medical evaluation of the 26-year-old singer.

Jamie Spears has had control over his daughter's affairs since February after she had several incidents of erratic behavior and hospitalizations.

• The ruling also occurred on the same day a Florida court case heated up in Los Angeles. One of Spears' former managers is suing the singer in Orlando wanted to force her to undergo a deposition. That move was blocked after Jamie Spears and his attorneys sought a protective order against his daughter answering questions. Goetz had approved the protective order through at least February.

• An attorney for uber-manager Johnny Wright, the man behind the New Kids on the Block and *NSYNC, says Spears seems well enough to record new music and is ready to embark on a publicity and concert tour for her new album, which will be released in December on her 27th birthday. The filings argued that Spears should also be considered healthy enough to undergo sworn testimony, but Goetz disagreed.
