No action shall be maintained by any claimant, except the state of Minnesota, against a county upon any claim except county orders, when the only relief demanded is a judgment for money, until the claim has been presented to the board and it has failed to act upon it within the time fixed by law, or the board consents to the institution of the action.
No action shall be brought by any person, except the state of Minnesota, upon any county order until the expiration of 30 days after a demand for payment of it has been made. Any judgment against the county entered in an action brought on an order without a demand is void.
