Register of valuers: removal, restoration, and five-year performance review govern continued registration and inquiry powers. Removal from the register of valuers may be made where the entry was made by error, misrepresentation or suppression of a material fact, or where the valuer's conviction, imprisonment, malpractice or professional misconduct shows unfitness to remain registered. A removed name may be restored on application and sufficient cause. The authorities must also review all registered valuers every five years and may remove a name for unsatisfactory performance after hearing and inquiry. The inquiry may be conducted by the authority or an Inquiry Officer with powers to secure evidence and attendance.
