CIVILIAN PERSONNEL Travel Travel expenses Travel orders Modification The Department of the Navy issued an employee a 365-day temporary duty order for duty in Italy on the basis of a cost comparison which showed that temporary duty was less expensive than a permanent change of station. The Navy's action was based on then-existing agency policy guidance. The well-established general rules are that legal rights and liabilities in regard to travel allowances vest as and when travel is performed under competent orders. That such orders may not be revoked or modified retroactively so as to increase or decrease the rights and benefits which have become fixed under the applicable statutes and regulations.
