(A)   No warrant for the payment of any obligation of the city shall be issued by the City Auditor until such obligation  shall have been approved by the head of the department for which the indebtedness was incurred and by the Mayor. Such officers and their sureties may be liable to the Municipality for all loss or damages sustained by the City by reason of the wrongful approval of any such obligation against the City.
   (B)   The City Auditor shall have the authority to refuse payment of any obligation of the City if the Auditor determines that the obligation is not in conformity to law or ordinance. For that purpose, the Auditor may summon before him any officer, agent, or employee, of any department of the City, or any other person, for examination upon oath or affirmation relative thereto.
