Interference with state and federal rights.

Should the contemplated improvements by any district interfere with any right or property of the federal government or any state government and it becomes necessary to obtain permission and consent of such governments or any of the departments or agents thereof, to carry out such improvements, the board shall enter into any compact, agreement or contract to obtain the necessary permission and consent for the purpose of making the improvements contemplated; provided, however, the failure of the board to obtain such permission and consent for the district shall not be taken advantage of by any property owner in any proceeding against the district and such failure shall only be questioned by such governments as shall have their rights interfered with.
