Consultant's Entitlement to Travel and per Diem Payments

An advance decision was requested as to whether a consultant may be paid for travel from his residence to his duty station and for per diem at his duty station for a certain period. As a temporary consultant, he was required to bear the cost of transportation from his place of residence to his official station. His later appointment as an intermittent consultant did not necessarily change the character of employment which determined whether he was entitled to payment. However, since the record concerning the nature of his employment was not clear, refund of payments should not be required for the period involved.
