(a) Authority to censure, suspend, or disbar. The Secretary of the Treasury, or delegate, after notice and an opportunity for a proceeding, may censure, suspend, or disbar any practitioner from practice before the Internal Revenue Service if the practitioner is shown to be incompetent or disreputable (within the meaning of § 10.51), fails to comply with any regulation in this part (under the prohibited conduct standards of § 10.52), or with intent to defraud, willfully and knowingly misleads or threatens a client or prospective client. Censure is a public reprimand.
(b) Authority to disqualify. The Secretary of the Treasury, or delegate, after due notice and opportunity for hearing, may disqualify any appraiser for a violation of these rules as applicable to appraisers.
(1) If any appraiser is disqualified pursuant to this subpart C, the appraiser is barred from presenting evidence or testimony in any administrative proceeding before the Department of Treasury or the Internal Revenue Service, unless and until authorized to do so by the Internal Revenue Service pursuant to § 10.81, regardless of whether the evidence or testimony would pertain to an appraisal made prior to or after the effective date of disqualification.
(2) Any appraisal made by a disqualified appraiser after the effective date of disqualification will not have any probative effect in any administrative proceeding before the Department of the Treasury or the Internal Revenue Service.
