In M'Donough v. Dannery and the Ship Mary Ford, the Supreme Court of the United States was asked to decide whether a ship that had been seized by French privateers during wartime could be sold in order to satisfy a judgment against its owner. The court held that such sales were permissible under international law, as long as they did not interfere with any rights or interests of other nations. Furthermore, it found that since France had declared war on Great Britain prior to the seizure of the vessel, there was no violation of neutrality laws and thus no impediment to selling off assets belonging to an enemy nation's citizens in order to pay debts owed by them. The decision established important precedent for how captured vessels should be treated during times of war and provided guidance on when foreign property can be used domestically without violating international law.

In M'Donough v. Dannery and the Ship Mary Ford, Justice Samuel Chase delivered a dissenting opinion in which he argued that the majority's decision was inconsistent with established maritime law. He noted that under existing admiralty practice, when two vessels collide at sea due to negligence or fault of either party, both parties are liable for damages incurred by each other. In this case, however, the majority had found only one vessel responsible for all losses suffered by both ships as a result of their collision - an outcome not supported by precedent or common sense. According to Justice Chase's dissent, it would be unfair and unjust if one ship were held solely accountable for any damage caused in such collisions; rather than apportioning responsibility between both vessels based on their respective degrees of fault or negligence. Ultimately then, Justice Chase concluded that while his colleagues may have been motivated by compassion towards those who lost property in this incident - they should not have done so at the expense of justice and equity within admiralty law itself.
