The issue in this case is whether Mamie Wilson is entitled to retirement credit for the period January, 1952 to September, 1958 when she was employed at the Lantana Tuberculosis Hospital. The Department takes the position that Ms. Wilson received a refund of her state employee retirement contribution of $449.09 on February 15, 1961 and is therefore not entitled to retirement credit for that period of service. Ms. Wilson takes the position that she never applied for nor received any refund of retirement contributions and thus her retirement should include credit for her employment at the tuberculosis hospital.Pet. Rec'd Retirement Benefits of $106 per mo. for 16.33 yrs of service. Res not petitioner to bear burden of proof Re: refund of retirement funds.
