I was terminated from a job. The DOL paid me unemployment benefits for months, my former employer appealed and after the hearing the dol ruled in my employer's favor and ordered me to pay back benefits. I do not have any current employment and the dol denied my request for waiver of overpayment. The letter states I can exercise my right to appeal. Is this something that has to be done in court or does this mean I have to send in a written letter to the department of labor?
