An interlocal agreement shall have the status of an interstate compact. In any case of controversy involving the performance or interpretation of the interlocal agreement or liability thereunder, the contracting public agencies shall be the real parties in interest, and the states in which they are located shall not be parties solely because of the status of the interlocal agreement as an interstate compact.
