Reconsideration of Claim for Per Diem Allowances

An officer in the Coast Guard Reserve appealed the disallowance of his claim for per diem allowances for a period during which he was on special active duty for training. Since the orders for the training were contingent upon waiver of per diem, the officer was held to have voluntarily waived per diem as permitted by regulations. A later amendment of the original travel orders after duty performance was begun which authorized per diem for the first 30 days and issuance of a second set of orders intending no per diem for the remaining 90 days could be given prospective effect only, beginning with the date the member had knowledge of the new orders.
