Western Union Telegraph Co. v. Call Publishing Co.

Background

A small local publisher sued a telegraph company after learning it was charged $5 per 100 words while a competing newspaper paid $1.50 for the same Associated Press dispatches. The telegraph company argued these services were interstate commerce and that, because Congress had not passed a controlling law, there was no rule to prevent different charges. After an initial trial and appeal in state court, a second jury returned a verdict for the publisher based on detailed instructions about when rate differences are unfair.

Reasoning

The central question was whether interstate carriers are free to set different rates when Congress has not spoken. The Court rejected the telegraph company’s claim that no law applies in such situations. It explained that general common-law principles — long-established rules and customs that govern fairness between businesses and customers — still limit carriers unless Congress enacts a contrary rule. The Court also emphasized that the state court had evidence about service conditions and that the jury’s factual finding about discrimination was a matter for the state courts to decide.

Real world impact

The decision means businesses and newspapers can use long-standing fairness rules to challenge unequal rates by interstate carriers when Congress has not regulated the specific practice. It upholds the jury’s role in weighing evidence about differing service conditions and measuring whether a price gap is unjust. The Supreme Court affirmed the Nebraska court’s judgment for the publisher, leaving the factual discrimination finding intact.
