In the case of Western Union Telegraph Company v. State of Georgia, as owner of Western & Atlantic R.R., et al., 1925, the Supreme Court was asked to determine whether a state could regulate rates for intrastate telegraph messages sent by railroad companies. The dispute arose when Georgia enacted legislation that set maximum charges for such services provided by Western Union Telegraph Company on lines owned by the state-operated Western & Atlantic Railroad. The company argued this violated their contract with the railroad and infringed upon its rights under both federal law and U.S Constitution's Contract Clause (Article I, Section 10). However, in a unanimous decision delivered by Justice Sutherland, it was held that states have authority over local commerce within their borders unless Congress has specifically legislated otherwise or if there is direct conflict with federal law. Therefore, Georgia’s regulation did not violate any constitutional provision nor interfere with interstate commerce regulations.

In the dissenting opinion for Western Union Telegraph Company v. State of Georgia, it was argued that the majority's decision to uphold a state law requiring telegraph companies to prioritize messages in order of receipt rather than importance or urgency was incorrect. The dissenting justices believed this ruling violated the Commerce Clause by allowing states to regulate interstate commerce, which they saw as an overreach of state power and a potential hindrance to efficient business operations. They also felt that such regulation could potentially disrupt important communications during emergencies or other critical situations where time-sensitive information needed immediate transmission. Furthermore, they disagreed with the majority's interpretation of "telegraph company" under federal law and thought it should include all businesses providing similar services regardless if their primary function is not sending telegrams.
