In the event that an agreement entered into pursuant to this chapter is between or among one (1) or more public agencies of this state and one (1) or more public agencies of another state or of the United States, the agreement shall have the status of an interstate compact, but in any case or controversy involving performance or interpretation thereof or liability thereunder, the public agencies party thereto shall be real parties in interest and the state may maintain an action to recoup or otherwise make itself whole for any damages or liability which it may incur by reason of being joined as a party therein.
