2. Determination.   A representative designated by the commissioner, and in this chapter referred to as a deputy, shall promptly examine the first claim filed by a claimant in each benefit year and shall determine the weekly benefit amount and maximum benefit amount potentially payable to the claimant during that benefit year in accordance with section 1192, subsection 5.

The deputy shall promptly examine all subsequent claims filed and, on the basis of facts, shall determine whether or not that claim is valid with respect to sections 1192 and 1193, other than section 1192, subsection 5, or shall refer that claim or any question involved in the claim to the Division of Administrative Hearings or to the commission, which shall make a determination with respect to the claim in accordance with the procedure described in subsection 3 , except that in any case in which the payment or denial of benefits is subject to section 1193, subsection 4, the deputy shall promptly transmit a report with respect to that subsection to the Director of Unemployment Compensation upon the basis of which the director shall notify appropriate deputies as to the applicability of that subsection.

The deputy shall determine in accordance with section 1221, subsection 3, paragraph A, the proper employer's experience rating record, if any, against which benefits of an eligible individual must be charged, if and when paid.

The deputy shall promptly notify the claimant and any other interested party of the determinations and reasons for the determinations. Subject to subsection 11, unless the claimant or any such interested party, within 15 calendar days after that notification was mailed to the claimant's last known address, files an appeal from that determination, that determination is final, except that the period within which an appeal may be filed may be extended, for a period not to exceed an additional 15 calendar days, for good cause shown. If new evidence or pertinent facts that would alter that determination become known to the deputy prior to the date that determination becomes final, a redetermination is authorized, but that redetermination must be mailed before the original determination becomes final.

If an employer's separation report for an employee is not received by the office specified on the separation report within 10 days after that report was requested, the claim must be adjudicated on the basis of information at hand. If the employer's separation report containing possible disqualifying information is received after the 10-day period and the claimant is denied benefits by a revised deputy's decision, benefits paid prior to the date of the revised decision do not constitute an overpayment of benefits. Any benefits paid after the date of the revised decision constitute an overpayment.

If an employer files an amended separation report or otherwise raises a new issue as to the employee's eligibility or changes the wages or weeks used in determining benefits that results in a denial of benefits or a reduction of the weekly benefit amount, the benefits paid prior to the date the determination is mailed do not constitute an overpayment. Any benefits received after that date to which the claimant is not entitled pursuant to a new determination based on that new employer information constitute an overpayment.

If, during the period a claimant is receiving benefits, new information or a new issue arises concerning the claimant's eligibility for benefits or which affects the claimant's weekly benefit amount, benefits may not be withheld until a determination is made on the issue. Before a determination is made, written notice shall be mailed to the claimant and other interested parties, which must include the issue to be decided, the law upon which it is based, any factual allegations known to the bureau, the right to a fact-finding interview, the date and location of the scheduled interview and the conduct of the interview and appeal. The fact-finding interview must be scheduled not less than 5 days nor more than 14 days after the notice is mailed. The bureau shall include in the notice a statement notifying the claimant that any benefits paid prior to the determination may be an overpayment under applicable law and recoverable by the bureau if it is later determined that the claimant was not entitled to the benefits. If the claimant does not appear for the scheduled interview, the deputy shall make a determination on the basis of available evidence. The deputy shall make a prompt determination of the issue based solely on any written statements of interested parties filed with the bureau before the interview, together with the evidence presented by interested parties who personally appeared at the interview. Upon request and notice to all parties at the interview, the deputy may accept corroborative documentary evidence after the interview. In no other case may the deputy base a decision on evidence received after the interview has been held.
