Joseph McKenna, Danville Water Company v. Danville…
“ Under the sanction of the same statutes considered in the Freeport Case, the defendant in error, the city of Danville, contracted with the plaintiff in error, the water company, for the period authorized by the statute, and stipulated as to the rates to be paid for a public water supply. These rates were adhered to until, under the authority of the statute of the state of Illinois passed in 1891, referred to in the opinion in the Freeport Case, the defendant in error reduced the rates below the contract price. ”
