(2) Such contract when adopted by the common council of said city and accepted by the owner or owners of such public utility shall be submitted to the public service commission for its approval and upon such approval the same shall be filed as provided in s. 8.37 and submitted in such manner as the common council shall determine to a vote of the electors of such city at the next regular municipal election or at a special election called for that purpose, and such contract shall not become binding upon such city until approved by a majority vote of the qualified electors of such city voting thereon.

(3) It shall be the duty of the public service commission upon request joined in by both parties to any such contract to advise and cooperate with them in the making of audits, estimates and other determinations of fact which will aid the parties in reaching an agreement or in the operation of the property under such agreement.
(4) Insofar as the use, operation, service, management, control, sale, lease, purchase, extension, improvement, rates, value or earnings of the properties of the public utility or provisions looking toward the ultimate acquisition of the same are made subject to the terms of any contract provided for in sub. (1), and so long as said contract remains in force, the following sections of the statutes shall be inapplicable to the same: ss. 196.02 (1) and (2), 196.05, 196.09, 196.10, 196.11, 196.15, 196.16, 196.19 (6), 196.20, 196.22, 196.26, 196.28, 196.30, 196.37, 196.39, 196.40, 196.58, 196.70, 197.01 (2) to (4), 197.02, 197.03, 197.04, 197.05, 197.06, 197.08 and 197.09; provided that nothing in any contract made hereunder shall operate to prevent an appeal to the public service commission by any person, other than a party to said contract, upon any complaint alleging that any rate, fare, charge or classification, or any joint rate, or any regulation, act or practice relating to the production, transmission, delivery or furnishing of gas, heat, light or power, or any service in connection therewith, is unjustly discriminatory, or that any such service is inadequate or cannot be obtained. Upon said appeal the commission shall, as provided by law, determine and by order fix a rate, fare, charge, classification, joint rate or regulation, act or practice or service to be imposed, observed or followed in the future in lieu of that found to be unjustly discriminatory or inadequate.
(5) Nothing in this section shall operate to deprive the public service commission of its jurisdiction over service, rates and other matters, as provided in chs. 196 and 197, outside of the limits of said 1st class city. If any complaint or investigation before the commission as to service, rates or other matters arising outside of any such city necessarily shall involve any contract authorized in sub.
