The City Auditor or Village Clerk shall not allow the amount set aside for any appropriation to be overdrawn, or the amount appropriated for one item of expense to be drawn upon for any other purpose or allow a voucher to be paid unless sufficient funds are in the Treasury of the municipal corporation to the credit of the fund upon which such voucher is drawn. When any claim is presented to the Auditor or Clerk, he or she may require evidence that such amount is due, and for this purpose may summon any agent, clerk or employee of the municipal corporation, or any other person, and examine him or her upon oath or affirmation concerning such voucher or claim.
