This case is an example of when it is best to leave well enough alone. Along the tortured path of this case, the parties switched positions i.e, plaintiff became defendant and vice versa. To keep it simple, I am going to refer to Ms. Allain by her last name and the two doctors as simply "the doctors".
While undergoing a procedure at Vanderbilt University Medical Center, Ms. Allain was told by the treating physician that a guide wire had been left in a vein leading to her heart. The treating physician opined the guide wire had been left during a prior procedure at Williamson Medical Center. Thereafter, Ms. Allain filed suit against Williamson Medical Center and the doctors. Several months after filing suit, Ms. Allain learned the guide wire was actually left by another Vanderbilt Medical Center physician. As such, she took a voluntary nonsuit against Williamson County Medical Center and the doctors.
Rather than being satisfied with the dismissal of the case against them, the doctors waited exactly one year and then filed suit against Ms. Allain for malicious prosecution and abuse of process. Summary judgment was denied on the malicious prosecution case and the trial court denied interlocutory appeal. The Court of Appeals granted a Rule 10 application but ultimately affirmed the denial of the motion for summary judgment. Next, the Tennessee Supreme Court reached down and took the case. Ultimately, the Tennessee Supreme Court, in a case of first impression, ruled a voluntary nonsuit pursuant to Rule 41 of the Tennessee Rules of Civil Procedure is not a favorable termination on the merits for purposes of a malicious prosecution case. Therefore, the doctors could not prove an essential element of their case. The Tennessee Supreme Court remanded the case to the trial court with instructions to enter summary judgment in favor of Ms. Allain on the malicious prosecution case and for a final determination on the abuse of process case.
