(d)
A judge who retires under subsection (a) or (b) may, at or after such retirement, be called upon by the chief judge of the Court of Federal Claims to perform such judicial duties with the Court of Federal Claims as may be requested of the retired judge for any period or periods specified by the chief judge, except that in the case of any such judge—
(1)
the aggregate of such periods in any one calendar year shall not (without his or her consent) exceed 90 calendar days; and
(2)
he or she shall be relieved of performing such duties during any period in which illness or disability precludes the performance of such duties.
Any act, or failure to act, by an individual performing judicial duties pursuant to this subsection shall have the same force and effect as if it were the act (or failure to act) of a Court of Federal Claims judge in regular active service. Any individual performing judicial duties pursuant to this subsection shall receive the allowances for official travel and other expenses of a judge in regular active service.
