5 U.S.C. § 6367: Receipt and use of leave from a leave bank

shall be submitted to the Leave Bank Board of the employing agency of the proposed leave recipient; and the name, position title, and grade or pay level of the proposed leave recipient; the reasons why leave is needed, including a brief description of the nature, severity, anticipated duration, and, if it is a recurring one, the approximate frequency of the medical emergency involved; if such Board so requires, certification from 1 or more physicians, or other appropriate experts, with respect to any matter under subparagraph (B); and any other information which such Board may reasonably require. The Leave Bank Board of an employing agency may approve an application submitted under subsection (a). A leave recipient may use annual leave received from the leave bank established by the employing agency of such employee under this subchapter in the same manner and for the same purposes as if such leave recipient had accrued such leave under section 6303, except that any annual leave and, if applicable, any sick leave accrued or accumulated to the leave recipient shall be used before any leave from the leave bank may be used. may accumulate without regard to any limitation under section 6304; and may be substituted retroactively for any period of leave without pay, or used to liquidate an indebtedness for any period of advanced leave, which began on or after a date fixed by the employing agency of the employee as the beginning of the medical emergency involved. Except to the extent that the Office of Personnel Management may prescribe regulations, nothing in the provisions of section 7351 shall apply to any solicitation, contribution, or use of leave to or from a leave bank under this subchapter.
