In the case of Pennsylvania Railroad Company v. Olivit Brothers, 1916, the U.S Supreme Court ruled in favor of Olivit Brothers. The dispute arose when a shipment of goods was damaged during transit by the railroad company and Olivit Brothers sought compensation for their losses. The court held that under the Carmack Amendment to Interstate Commerce Act (1906), which governs liability for loss or damage to goods transported across state lines, it is not necessary for a shipper to prove negligence on part of carrier; instead, they only need to show that they delivered goods in good condition and those were damaged when received at destination point. This ruling clarified an important aspect related with transportation law: once shippers have shown delivery in good condition but receipt in damaged state by consignee then burden shifts onto carriers who must either provide evidence showing they were free from negligence or that damage was due to one of excepted causes relieving them from liability.

In the dissenting opinion for Pennsylvania Railroad Company v. Olivit Brothers, it was argued that the majority's decision to hold the railroad company liable for damages caused by a fire started by sparks from one of its locomotives was incorrect. The dissenting justices believed that there wasn't enough evidence to conclusively prove that negligence on part of the railroad company led directly to the damage sustained by Olivit Brothers' property. They also pointed out inconsistencies in witness testimonies regarding whether or not proper spark arresters were used and if they could have prevented this incident. Furthermore, they disagreed with applying strict liability principles in this case as railroads are not inherently dangerous activities but rather common carriers obligated to serve public needs while operating under significant regulatory constraints which limit their ability to control all risks associated with their operations.
