In Pratt and Others v. Carroll, the Supreme Court of the United States heard a case concerning an alleged breach of contract between two parties. The plaintiff, Pratt and others, had contracted with defendant Carroll to transport goods from Baltimore to Philadelphia on his vessel for a certain price. When they arrived in Philadelphia, however, they found that some of their goods were missing or damaged due to negligence by Carroll's crew during transit. As such, Pratt and others sued for damages incurred as a result of this breach of contract. In its ruling on the case, the court held that although there was evidence suggesting negligence by Carroll's crew members while transporting the goods in question from Baltimore to Philadelphia did occur; it could not be conclusively proven that said negligence caused any damage or loss suffered by plaintiffs' property since no direct causal link could be established between them both. Thusly, judgment was rendered in favor of defendant Carroll as he had fulfilled all obligations under his contractual agreement with plaintiffs despite any potential negligent behavior exhibited by his employees during transit which may have resulted in losses incurred by plaintiffs' property at issue here today

In Pratt and Others v. Carroll, the Supreme Court was asked to decide whether a state court had jurisdiction over a case involving citizens of different states. The majority opinion held that the state court did not have jurisdiction because it would be in violation of Article III, Section 2 of the U.S. Constitution which gives exclusive original jurisdiction to federal courts when cases involve citizens from two or more states. However, Justice Johnson dissented on this ruling arguing that since there were no federal laws governing such matters at the time, then it should be left up to each individual state's legislature to determine their own jurisdictional limits for civil suits between its own citizens as well as those from other states within their borders. He argued further that if Congress wanted exclusive power over such matters they could pass legislation granting them authority but until then he believed it was best left up to each individual state's discretion and control so long as they followed due process procedures established by law in order for justice to prevail in all cases regardless of where one resided or what citizenship status they held at any given time
