by John Marshall Harlan, Smyth v. Ames (171 U.S. 361) — Opinion of the Court
“ It may well be that on some particular article the railroad companies may deem it wise to make a reduction of the rate, and it may be that the public interests will justify the state board of transportation in ordering such reduction. We have not laid down any cast-iron rule covering each and every separate rate. We only adjudged that the enforcement of the schedules of rates established by the state statute, looking at such rates as a whole, would deprive the railroad companies of the compensation they were legally entitled to receive. ”
