LOS ANGELES - A judge is putting the brakes on Britney Spears' driving-without-a-licence case, after her lawyers told him they don't believe the troubled pop star is capable of resolving the matter.

Judge T.K. Herman has continued the misdemeanour case until March 20.

Lawyer J. Michael Flanagan said Wednesday that the pop-star's attorneys do not think Spears is capable of giving a deposition, signing a declaration or entering into a binding agreement.

Earlier this month a judge placed Spears under the conservatorship of her father and an attorney after more than a year of increasingly bizarre behaviour.

The driving-without-a-licence charge stems from an Aug. 6, 2007, accident in which Spears hit a parked car and left without notifying the owner.
