For purposes of this part:

Outside employment or activity means any form of non-Federal employment or business relationship, compensated or uncompensated, involving the provision of personal services by the employee. It includes, but is not limited to:

(1) Personal services as an officer, director, employee, agent, attorney, consultant, contractor, general partner, trustee, teacher, professor, speaker, or writer.

(2) Active participation, including voluntary participation as defined in 5 CFR 2635.502(b)(1)(v), with a prohibited source.

(3) It does not include participation in the activities of a nonprofit charitable, religious, professional, social, fraternal, educational, recreational, public service, or civic organization, unless such activities are for compensation other than reimbursement of expenses; such activities involve the provision of professional services or advice; or the organization's activities are devoted substantially to matters relating to the employee's official duties as defined in 5 CFR 2635.807(a)(2)(i)(B) through (E).

Note 1 to § 10300.102.

There is a special approval requirement set out in both 18 U.S.C. 203(d) and 205(e) for certain representational activities otherwise covered by the conflict-of-interest restrictions on compensation and activities of employees in claims against and other matters affecting the Government. Thus, an employee who wishes to act as an agent or attorney for, or otherwise represent the employee's parents, spouse, child, or any person for whom, or any estate for which, the employee is serving as guardian, executor, administrator, trustee, or other personal fiduciary in such matters, must obtain the approval required by law of the government official responsible for the employee's appointment, in addition to the regulatory approval required in this section.
