Section 630.1706 - Cases of employee incapacitation(a) If an agency determines that an otherwise eligible employee who could have made an election during a past period to substitute paid parental leave (as provided in § 630.1703 ) and enter a work obligation agreement (as described in § 630.1705 ) was physically or mentally incapable of doing so during that past period, the employee may, within 5 workdays of the employee's return to duty status, make an election to substitute paid parental leave for applicable FMLA unpaid leave under § 630.1703(a) on a retroactive basis. Such a retroactive election shall be effective on the date that such an election would have been effective if the employee had not been incapacitated at the time. Consistent with § 630.1206(f)(4) , this retroactive election must be made in conjunction with a retroactive election under § 630.1203(b) , if the FMLA unpaid leave was not already approved. As part of such election, the employee must agree (in writing, as described in § 630.1705(b)(1) ) to meet the work obligation or pay the required reimbursement (if applicable) unless- (1) Applying the work obligation and the associated reimbursement requirement is barred under § 630.1705(f)(2) ; or(2) The agency later concludes under its policies established under § 630.1705(f)(1) that the circumstances support a determination to not apply the reimbursement requirement.(b)(1) If an agency determines that an otherwise eligible employee is physically or mentally incapable of making an election to substitute paid parental leave (as provided in § 630.1703 ) and entering into a work obligation agreement (as described in § 630.1705 ), the agency must, upon the request of a personal representative of the employee whom the agency finds acceptable, provide conditional approval of substitution of paid parental leave for applicable FMLA unpaid leave under § 630.1703(a) on a prospective basis. The conditional approval is based on the presumption that the employee would have elected to substitute paid parental leave for the applicable FMLA unpaid leave and would have entered into the work obligation agreement if the employee had not been incapacitated. Within 5 workdays after returning to work, the employee must enter into a written agreement to meet the work obligation described in § 630.1705 or pay the required reimbursement (if applicable) unless-(i) Applying the work obligation and the associated reimbursement requirement is barred under § 630.1705(f)(2) ; or(ii) The agency later concludes under its policies established under § 630.1705(f)(1) that the circumstances support a determination to not apply the reimbursement requirement.(2) If an employee covered by paragraph (b)(1) of this section declines to enter into the written agreement after being determined by the agency to no longer be incapacitated, the agency must cancel any portion of the 12 weeks of paid parental leave that has not been exhausted, and designate as invalid any paid parental leave that was used based on the conditional approval. The time covered by the invalidated paid parental leave must be converted to leave without pay unless the employee requests that other paid leave or paid time off to the employee's credit be applied (as appropriate) in place of the invalidated paid parental leave. To the extent the employee has invalidated paid parental leave hours not replaced by other paid leave or paid time off, pay received for those hours is a debt to the employing agency and is subject to collection under the Federal Claims Collection Standards in 31 CFR parts 900 through 904 .
