Supreme Court of the United States January 22, 1900, 131 (Chicago, Milwaukee & St. Paul Railway Co. v. Tompkins)

Mr. Justice Brewer

delivered the opinion of the court.

New cases are more difficult or perplexing than those which involve an inquiry whether the rates prescribed by a state legislature for'the carriage of passengers and freight are unreasonable. ■ And yet this difficulty affords no excuse for a failure to examine and solve the questions involved.
