Question

In which Supreme Court decision did the court rule that a state could not regulate railroad rates because the railroad carried freight across state lines?

Answer 1

B.

Wabash v. Illinois

Answer 2

Wabash, St. Louis and the Pacific Railway Company v. Illinois

In this case, the Supreme Court ruled that commerce and trade that crossed state lines was directly under the authority of the federal government. This effectively reversed the decision that had been made in Peik v. the Chicago and Northwestern Railway
