No. 91-2662.
District Court of Appeal of Florida, Fourth District.

ON MOTION FOR REHEARING
OWEN, WILLIAM C., JR., Senior Judge.
We grant the motion for rehearing and substitute the following opinion for the opinion filed October 14, 1992.
As a sanction for conduct which the trial judge perceived to be a fraud on the court by appellant,[1] her personal injury complaint was dismissed and judgment was entered for the defendant. We reverse.
The trial court has the inherent authority, in the exercise of its sound judicial discretion, to dismiss an action when the plaintiff has perpetrated a fraud on the court,[2] or where a party,[3] or the party's counsel,[4] persistently fails or refuses to comply with court orders. Because dismissal is the most severe of all possible sanctions, it should be employed only in extreme circumstances.[5] In some cases, where the misconduct of a party or the party's counsel has permeated the entire proceeding, dismissal of the entire case has been upheld,[6] but in others where the fraud or other misconduct pertained to only a part of the claim, dismissal of the unaffected legitimate part of the claim has been held to be too severe.[7]
In this case the record does not establish that appellant either authorized *140 or had any prior knowledge of her counsel's inclusion in the complaint of the offending allegations and claim.[8] Furthermore, the separate count on behalf of appellant's husband had been voluntarily dismissed, and attorney's fees had been awarded to appellees' trial counsel. Under the circumstances, we conclude that the trial court abused its discretion in dismissing appellant's claim for her own personal injuries.
The judgment and the order dismissing appellant's complaint are severally reversed.
GLICKSTEIN, C.J., and DELL, J., concur.
