The Michigan Central R. Co. v. Myrick case was an action for breach of contract brought by Paris Myrick against the Michigan Central Railroad Company. Myrick alleged that the company had breached two contracts to carry 202 head of cattle from Chicago to Philadelphia and deliver them to his order. The Supreme Court of the United States ruled in favor of the railroad company, stating that the common law imposes no greater duty than the safe delivery of goods at the destination, and that any additional responsibilities must be agreed upon in a special contract. This decision established that railroads were not liable for damages resulting from delays or losses caused by circumstances beyond their control, such as strikes or natural disasters. As a result, this case had a significant impact on the use of railroad companies in the United States, as it limited their liability and protected them from potential financial losses due to unforeseen events.
