(a) Except as provided in paragraph (b), when any former member accepts a refund, all existing service credits and all rights and benefits to which the person was entitled prior to the acceptance of the refund must terminate.
(b) A refund under section 353.651, subdivision 3, paragraph (c), does not result in a forfeiture of salary credit for the allowable service credit covered by the refund.
(c) The rights and benefits of a former member must not be restored until the person returns to active service and acquires at least six months of allowable service credit after taking the last refund and repays the refund or refunds taken and interest received under section 353.34, subdivisions 1 and 2, plus interest at an annual rate of 8.5 percent compounded annually. If the person elects to restore service credit in a particular fund from which the person has taken more than one refund, the person must repay all refunds to that fund. All refunds must be repaid within six months of the last date of termination of public service.
A person who receives a refund of accumulated employee deductions, plus interest, may repay the total amount of the refund including the interest, within 30 days of the date the refund was issued, to retain allowable service.
