Joseph McKenna, Rogers Park Water Company v. Fergus…
“ The fixing of rates is plainly generic, and of necessity embraced those rates which were to be paid for the supply of water which the statute authorized the city to contract for. So far as the power of the legislature to authorize a contract for designated rates for a stipulated time is concerned, I can see no difference between fixing the rates for the public and those for the private supply during the authorized time. ”
