5 CFR § 2635.104 - Applicability to employees on detail.
(a)Details to other agencies. Except as provided in paragraph (d) of this section, an employee on detail, including a uniformed officer on assignment, from his employing agency to another agency for a period in excess of 30 calendar days shall be subject to any supplemental agency regulations of the agency to which he is detailed rather than to any supplemental agency regulations of his employing agency.
(b)Details to the legislative or judicial branch. An employee on detail, including a uniformed officer on assignment, from his employing agency to the legislative or judicial branch for a period in excess of 30 calendar days shall be subject to the ethical standards of the branch or entity to which detailed. For the duration of any such detail or assignment, the employee shall not be subject to the provisions of this part, except this section, or, except as provided in paragraph (d) of this section, to any supplemental agency regulations of his employing agency, but shall remain subject to the conflict of interest prohibitions in title 18 of the United States Code.
(c)Details to non-Federal entities. Except to the extent exempted in writing pursuant to this paragraph, an employee detailed to a non-Federal entity remains subject to this part and to any supplemental agency regulation of his employing agency. When an employee is detailed pursuant to statutory authority to an international organization or to a State or local government for a period in excess of six months, the designated agency ethics official may grant a written exemption from subpart B of this part based on his determination that the entity has adopted written ethical standards covering solicitation and acceptance of gifts which will apply to the employee during the detail and which will be appropriate given the purpose of the detail.
(d)Applicability of special agency statutes. Notwithstanding paragraphs (a) and (b) of this section, an employee who is subject to an agency statute which restricts his activities or financial holdings specifically because of his status as an employee of that agency shall continue to be subject to any provisions in the supplemental agency regulations of his employing agency that implement that statute.
