In Warner v. Baltimore and Ohio Railroad Company, the U.S Supreme Court ruled in favor of the railroad company, stating that it was not liable for damages caused by a fire started by sparks from one of its locomotives. The plaintiff, Warner, had sued for compensation after his property was damaged in such an incident. However, the court held that since there were no negligence or violation of safety regulations on part of the railroad company and because railroads are considered a public necessity with inherent risks associated with their operation (such as occasional fires), they could not be held responsible unless proven negligent or reckless. This case set a precedent regarding liability issues related to damage caused by unavoidable hazards linked to necessary public services.

In the dissenting opinion for Warner v. Baltimore and Ohio Railroad Company, it was argued that the majority's decision to hold a railroad company liable for damages caused by sparks from its locomotive was unjustified. The dissenting justices believed that there were insufficient precautions taken by the plaintiff in protecting his property from such an eventuality, which is common knowledge and occurrence associated with railroads' operations. They contended that while railroads should exercise due care in their operations, they cannot be expected to completely eliminate all risks inherent in running trains powered by steam engines - including emitting sparks. Therefore, according to this view, unless negligence on part of the railroad can be proven or if there are specific laws requiring them to ensure no damage occurs due to their operation (which wasn't case here), holding them responsible would not only be unfair but also potentially detrimental for progress as it could discourage use of efficient technologies fearing liabilities.
