Executive Order 10450
Security Requirements for Government Employment
Whereas the interests of the national security require that all persons privileged to be employed in the departments and agencies of the Government, shall be reliable, trustworthy, of good conduct and character, and of complete and unswerving loyalty to the United States; and
Whereas the American tradition that all persons should receive fair, impartial, and equitable treatment at the hands of the Government requires that all persons seeking the privilege of employment or privileged to be employed in the departments and agencies of the Government be adjudged by mutually consistent and no less than minimum standards and procedures among the departments and agencies governing the employment and retention in employment of persons in the Federal service:
Now, Therefore, by virtue of the authority vested in me by the Constitution and statutes of the United States, including section 1753 of the Revised Statutes of the United States (5 U.S.C. 631); the Civil Service Act of 1883 (22 Stat. 403; 5 U.S.C. 632, et seq.); section 9A of the act of August 2, 1939, 53 Stat. 1148 (5 U.S.C. 118j); and the act of August 26, 1950, 64 Stat. 476 (5 U.S.C. 22-1, et seq.), and as President of the United States, and deeming such action necessary in the best interests of the national security, it is hereby ordered as follows:

##### Section 1.

    In addition to the departments and agencies specified in the said act of August 26, 1950, and Executive Order No. 10237 of April 26, 1951, the provisions of that act shall apply to all other departments and agencies of the Government.

##### Sec. 2.

    The head of each department and agency of the Government shall be responsible for establishing and maintaining within his department or agency an effective program to insure that the employment and retention in employment of any civilian officer or employee within the department or agency is clearly consistent with the interests of the national security.

##### Sec. 3.

| (a) | The appointment of each civilian officer or employee in any department or agency of the Government shall be made subject to investigation. The scope of the investigation shall be determined in the first instance according to the degree of adverse effect the occupant of the position sought to be filled could bring about, by virtue of the nature of the position, on the national security, but in no event shall the investigation include less than a national agency check (including a check of the fingerprint files of the Federal Bureau of Investigation), and written inquiries to appropriate local law-enforcement agencies, former employers and supervisors, references, and schools attended by the person under investigation: Provided, that upon request of the head of the department or agency concerned, the Civil Service Commission may, in its discretion, authorize such less investigation as may meet the requirements of the national security with respect to per-diem, intermittent, temporary, or seasonal employees, or aliens employed outside the United States. Should there develop at any stage of investigation information insistent with the interests of the national security, there shall be conducted with respect to such person a full field investigation, or such less investigation as shall be sufficient to enable the head of the department or agency concerned to determine whether retention of such person is clearly consistent with the interests of the national security. |
| (b) | The head of any department or agency shall designate, or cause to be designated, any position within his department or agency the occupant of which could bring about, by virtue of the nature of the position, a material adverse effect on the national security as a sensitive position. Any position so designated shall be filled or occupied only by a person with respect to whom a full field investigation has been conducted: Provided, that a person occupying a sensitive position at the time it is designated as such may continue to occupy such position pending the completion of a full field investigation, subject to the other provisions of this order: And provided further, that in case of emergency a sensitive position may be filled for a limited period by a person with respect to whom a full field preappointment investigation has not been completed if the head of the department or agency concerned finds that such action is necessary in the national interest, which finding shall be made a part of the records of such department or agency. |

##### Sec. 4.

    The head of each department and agency shall review, or cause to be reviewed, the cases of all civilian officers and employees with respect to whom there has been conducted a full field investigation under Executive Order No. 9835 of March 21, 1947, and, after such further investigation as may be appropriate, shall re-adjudicate, or cause to be re-adjudicated, in accordance with the said act of August 26, 1950, such of those cases as have not been adjudicated under a security standard commensurate with that established under this order.

##### Sec. 5.

    Whenever there is developed or received by any department or agency information indicating that the retention in employment of any officer or employee of the Government may not be clearly consistent with the interests of the national security, such information shall be forwarded to the head of the employing department or agency or his representative, who, after such investigation as may be appropriate, shall review, or cause to be reviewed, and, where necessary, re-adjudicate, or cause to be re-adjudicated, in accordance with the said act of August 26, 1950, the case of such officer or employee.

##### Sec. 6.

    Should there develop at any stage of investigation information indicating that the employment of any officer or employee of the Government may not be clearly consistent with the interests of the national security, the head of the department or agency concerned or his representative shall immediately suspend the employment of the person involved if he deems such suspension necessary in the interests of the national security and, following such investigation and review as he deems necessary, the head of the department or agency concerned shall terminate the employment of such suspended officer or employee whenever he shall determine such termination necessary or advisable in the interests of the national security, in accordance with the said act of August 26, 1950.

##### Sec. 7.

    Any person whose employment is suspended or terminated under the authority granted to heads of departments and agencies by or in accordance with the said act of August 26, 1950, or pursuant to the said Executive Order No. 9835 or any other security or loyalty program relating to officers or employees of the Government, shall not be reinstated or restored to duty or reemployed in the same department or agency and shall not be reemployed in any other department or agency, unless the head of the department or agency concerned finds that such reinstatement, restoration, or reemployment is clearly consistent with the interests of the national security, which finding shall be made a part of the records of such department or agency: Provided, that no person whose employment has been terminated under such authority thereafter may be employed by any other department or agency except after a determination by the Civil Service Commission that such person is eligible for such employment.

##### Sec. 8.

| (a) | The investigations conducted pursuant to this order shall be designed to develop information as to whether the employment or retention in employment in the Federal service of the person being investigated is clearly consistent with the interests of the national security. Such information shall relate, but shall not be limited, to the following: |
| (1) | Depending on the relation of the Government employment to the national security: |
| (i) | Any behavior, activities, or associations which tend to show that the individual is not reliable or trustworthy. |

| (iii) | Any criminal, infamous, dishonest, immoral, or notoriously disgraceful conduct, habitual use of intoxicants to excess, drug addiction, or sexual perversion. |
| (iv) | An adjudication of insanity, or treatment for serious mental or neurological disorder without satisfactory evidence of cure. |
| (v) | Any facts which furnish reason to believe that the individual may be subjected to coercion, influence, or pressure which may cause him to act contrary to the best interests of the national security. |
| (2) | Commission of any act of sabotage, espionage, treason, or sedition, or attempts thereat or preparation therefor, or conspiring with, or aiding or abetting, another to commit or attempt to commit any act of sabotage, espionage, treason, or sedition. |
| (3) | Establishing or continuing a sympathetic association with a saboteur, spy, traitor, seditionist, anarchist, or revolutionist, or with an espionage or other secret agent or representative of a foreign nation, or any representative of a foreign nation whose interests may be inimical to the interests of the United States, or with any person who advocates the use of force or violence to overthrow the government of the United States or the alteration of the form of government of the United States by unconstitutional means. |
| (4) | Advocacy of use of force or violence to overthrow the government of the United States, or of the alteration of the form of government of the United States by unconstitutional means. |
| (5) | Membership in, or affiliation or sympathetic association with, any foreign or domestic organization, association, movement, group, or combination of persons which is totalitarian, Fascist, Communist, or subversive, or which has adopted, or shows, a policy of advocating or approving the commission of acts of force or violence to deny other persons their rights under the Constitution of the United States, or which seeks to alter the form of government of the United States by unconstitutional means. |
| (6) | Intentional, unauthorized disclosure to any person of security information, or of other information disclosure of which is prohibited by law, or willful violation or disregard of security regulations. |
| (7) | Performing or attempting to perform his duties, or otherwise acting, so as to serve the interests of another government in preference to the interests of the United States. |

The Commission shall furnish a full investigative report to the department or agency concerned. |
| (c) | The investigation of persons (including consultants, however employed), entering employment of, or employed by, the Government other than in the competitive service shall primarily be the responsibility of the employing department or agency. Departments and agencies without investigative facilities may use the investigative facilities of the Civil Service Commission, and other departments and agencies may use such facilities under agreement with the Commission. |
| (d) | There shall be referred promptly to the Federal Bureau of Investigation all investigations being conducted by any other agencies which develop information indicating that an individual may have been subjected to coercion, influence, or pressure to act contrary to the interests of the national security, or information relating to any of the matters described in subdivisions (2) through (7) of subsection (a) of this section. In cases so referred to it, the Federal Bureau of Investigation shall make a full field investigation. |

##### Sec. 9.

| (a) | There shall be established and maintained in the Civil Service Commission a security-investigations index covering all persons as to whom security investigations have been conducted by any department or agency of the Government under this order. The central index established and maintained by the Commission under Executive Order No. 9835 of March 21, 1947, shall be made a part of the security-investigations index. The security-investigations index shall contain the name of each person investigated, adequate identifying information concerning each such person, and a reference to each department and agency which has conducted an investigation concerning the person involved or has suspended or terminated the employment of such person under the authority granted to heads of departments and agencies by or in accordance with the said act of August 26, 1950. |
| (b) | The heads of all departments and agencies shall furnish promptly to the Civil Service Commission information appropriate for the establishment and maintenance of the security-investigations index. |
| (c) | The reports and other investigative material and information developed by investigations conducted pursuant to any statute, order, or program described in section 7 of this order shall remain the property of the investigative agencies conducting the investigations, but may, subject to considerations of the national security, be retained by the department or agency concerned. Such reports and other investigative material and information shall be maintained in confidence, and no access shall be given thereto except, with the consent of the investigative agency concerned, to other departments and agencies conducting security programs under the authority granted by or in accordance with the said act of August 26, 1950, as may be required for the efficient conduct of Government business. |

* ↑ Correction of Error in CFR Reprint The text of paragraph (iii) of section 8(a)(1) of Executive Order 10450 as reprinted in the Code of Federal Regulations (1953 Supplement and 1949-1953 Compilation) is corrected by deleting the phrase "financial irresponsibility" and transposing the conjunction "or" so that paragraph (iii) reads as follows: (iii)   Any criminal, infamous, dishonest, immoral, or notoriously disgraceful conduct, habitual use of intoxicants to excess, drug addiction, or sexual perversion. It should be noted that the text of paragraph (iii) was published correctly in the federal register of April 29,1953 (18 F.R. 2491).
