Legal Question in Personal Injury in California

If there is only one plaintiff, the plaintiff can't simply "withdraw." If you want to withdraw, the correct term is "dismissal" of the action. In essence, you are withdrawing the lawsuit, not the plaintiff. If you file the motion to dismiss without prejudice, you can likely bring the case back again before the statute of limitations expires. If you file with prejudice, you cannot bring the same lawsuit against the same defendant at a later date.
