New Hampshire Supreme Court Vacates Arbitration Award Based on “Plain Mistake” of Law

The city of Portsmouth terminated a police officer in the wake of a bequest made to the officer by a 92-year-old woman he had met while on duty. The officer had assisted the woman in finding an attorney to draft a new will leaving the majority of her estate to him, which she executed months before her death. Afterward, the city convened a task force to conduct an independent inquiry into the officer’s relationship with the decedent. The task force concluded that the officer’s actions violated the Portsmouth Code of Ethics and the Portsmouth Police Department Duty Manual, and the city terminated him based on the task force’s recommendation.

The beneficiaries of the decedent’s prior will had also initiated an action to contest the new will. That action resulted in a probate decision that concluded the new will must be invalidated due to undue influence by the officer. The probate decision was issued approximately one month after the city had already terminated the officer.

Meanwhile, the police union had filed a grievance under the collective bargaining agreement, which had been referred to arbitration. The city notified the union that it intended to introduce the probate decision at the arbitration hearing to justify the termination and as mitigating evidence relative to any remedy. After litigation of the issue, the probate decision was admitted as “after-acquired evidence” for purposes of determining the appropriate remedy but was not admitted to supply the “just cause” for the termination itself.

The arbitrator found that the officer’s misconduct was “severe” but nevertheless determined the city wrongfully terminated the officer due to its failure to correctly enforce its own rules and to properly supervise him. The arbitrator awarded the officer back pay from the date of his termination to the date the arbitrator held the firing to be unsupported by just cause. The city challenged the award in the New Hampshire Superior Court, arguing the arbitrator had made a “plain mistake” of law in determining the period of back pay, based in part on her rulings related to the introduction of the after-acquired evidence. The superior court confirmed the award.

On appeal, however, the New Hampshire Supreme Court reversed. The court noted that the “after-acquired evidence” doctrine applies to evidence of an employee’s misconduct — discovered by the employer after it has terminated the employee for an unlawful reason — which is so severe that the employer would have terminated the employee on those grounds alone had it known of the misconduct at the time of the discharge. After-acquired evidence may be introduced to bar or limit an employee’s recovery, but it may not be introduced to provide a basis for the termination itself.

Here, the arbitrator held that the city had not complied with due process requirements (imposed by Cleveland Board of Education v. Loudermill) to provide notice to an employee of the grounds for termination and an opportunity to be heard. However, the Loudermill requirements do not apply to after-acquired evidence, which concerns the calculation of damages resulting from a wrongful termination as opposed to the basis for the termination itself. As such, the city was not required to comply with the Loudermill notice requirements when it sought to introduce and rely on the after-acquired evidence in support of its argument to limit the officer’s recovery. The Supreme Court held that the arbitrator had committed a plain mistake of law, and vacated the lower court’s confirmation and directed it to remand the case to the arbitrator to reconsider the back pay award.
