§ 651. Expiration of plaintiff's title before trial. If the right or

title of the plaintiff expires after the commencement of the action but

before the trial, and he would have been entitled to recover but for the

to the fact; and the plaintiff is entitled nevertheless to judgment for

his damages for the withholding of the property to the time when his

right or title so expired.
