5 CFR 731.204 - Debarment by OPM.
(a) When OPM finds a person unsuitable for any reason listed in § 731.202, OPM, in its discretion, may, for a period of not more than 3 years from the date of the unfavorable suitability determination, deny that person examination for, and appointment to, covered positions.
(b) OPM may impose an additional period of debarment following the expiration of a period of OPM or agency debarment, but only after the person again becomes an applicant, appointee, or employee subject to OPM's suitability jurisdiction, and his or her suitability is determined in accordance with the procedures of this part. An additional debarment period may be based in whole or in part on the same conduct on which the previous suitability action was based, when warranted, or new conduct.
(c) OPM, in its sole discretion, determines the duration of any period of debarment imposed under this section.
