Justice Douglas read the majority's language as dangerously broad. In his view, statements that Grafton had an "exclusive" right to serve its inhabitants and that Ohio Edison was an "occupant at sufferance" suggested that Grafton could summarily expel Ohio Edison altogether, despite the Miller Act's protection for the utility's existing service. He saw an unresolved conflict between those statements and the majority's acknowledgment that Ohio Edison's right to continue serving customers covered by its franchises remained secure under the Act.
Douglas maintained that the Miller Act requires a municipality to seek PUCO approval before forcing a private utility to abandon service or facilities within municipal limits, even after a franchise expires or where the utility never held a valid franchise. He relied on Lake Shore Electric Railway Co. v. State ex rel. Martin and State ex rel. Klapp v. Dayton Power & Light Co. for that proposition.
He also stressed that the challenged lines were located entirely on private property, did not cross public streets or rights-of-way, and were not prohibited by a Grafton ordinance or other law. In his view, Ohio Edison could supply customers who chose its service under those circumstances, particularly because Grafton had not affirmatively prohibited the activity.
Douglas accepted that Grafton could operate a municipal utility and could establish a monopoly by acquiring Ohio Edison's facilities, withholding future franchises, and restricting use of public rights-of-way. But he concluded that Grafton should not be allowed to constructively confiscate Ohio Edison's right to serve existing customers, or new customers reachable without municipal rights-of-way, without compensation and without PUCO review.
Finally, Douglas framed the dispute as one about consumer choice and the coming development of competitive electricity sales. He feared that the majority's rule would replace a regulated investor-owned utility monopoly with an unregulated municipal monopoly, allowing local government rather than customers to decide which electric provider they may use. Justice Resnick joined his dissent.
