The evidence may be either oral or documented, as required by the department. The department shall, after making the examination and investigation, endorse on the certificate or claim its approval or disapproval of it, and if the certificate or claim or any part of it is disapproved, the endorsement shall state the reasons for the disapproval. If a certificate or claim is approved, it shall be processed as provided by law.
