In the case of Rufus Allen and Others v. Henry L. Newberry, the Supreme Court was asked to decide whether a steamboat captain had acted negligently in causing an accident that resulted in injury and death for some passengers on board his vessel. The libellants argued that the claimant, Captain Newberry, had failed to take proper precautions when navigating through dangerous waters which led to a collision with another boat resulting in injuries and deaths among those aboard his own vessel. The court found that while there were certain navigational errors made by Captain Newberry, they did not amount to negligence as he had taken reasonable care under the circumstances at hand; thus ruling against the libellants’ claims of negligence on behalf of Captain Newberry. Ultimately this decision established precedent regarding what constitutes negligent behavior from captains operating vessels within U.S waters - namely that any failure must be substantial enough so as to constitute gross negligence or recklessness before it can be considered actionable under maritime law

In the case of Rufus Allen and Others v. Henry L. Newberry, the Supreme Court was asked to decide whether a steamboat called Fashion had been legally sold by its owner in order to pay off debts owed by him. The majority opinion held that the sale was valid because it had been made with proper notice and without any fraud or collusion on either side; however, Justice Grier dissented from this decision. He argued that there were several irregularities in the proceedings leading up to the sale which should have invalidated it: for example, he noted that some of those who purchased shares at auction did not receive their certificates until after they paid for them; additionally, he pointed out that no proof was offered as to how much money each bidder actually put down when purchasing his share. Furthermore, Grier contended that since none of these issues were addressed during trial or appeal proceedings before reaching the Supreme Court level, they could not be considered now - thus making it impossible for him to agree with his colleagues' ruling on this matter.
