The head of an agency may fill excepted positions by the appointment of persons without civil service eligibility or competitive status and such persons shall not acquire competitive status by reason of such appointment: Provided, That OPM, in its discretion, may by regulation prescribe conditions under which excepted positions may be filled in the same manner as competitive positions are filled and conditions under which persons so appointed may acquire a competitive status in accordance with the Civil Service Rules and Regulations.

To the extent permitted by law and the provisions of this part, and subject to the suitability and fitness requirements of the applicable Civil Service Rules and Regulations, appointments and position changes in the excepted service shall be made in accordance with such regulations and practices as the head of the agency concerned finds necessary. These shall include, for the position of administrative law judge appointed under 5 U.S.C. 3105, the requirement that, at the time of application and any new appointment, the individual, other than an incumbent administrative law judge, must possess a professional license to practice law and be authorized to practice law under the laws of a State, the District of Columbia, the Commonwealth of Puerto Rico, or any territorial court established under the United States Constitution. For purposes of this requirement, judicial status is acceptable in lieu of “active” status in States that prohibit sitting judges from maintaining “active” status to practice law, and being in “good standing” is also acceptable in lieu of “active” status in States where the licensing authority considers “good standing” as having a current license to practice law. This requirement shall constitute a minimum standard for appointment to the position of administrative law judge, and such appointments may be subject to additional agency requirements where appropriate.
