This case involved a dispute between Adrian B. Bentzon, the claimant of thirty hogsheads of sugar, and Boyle and others who were officers and crew members of the privateer Comet. The claim was that the defendants had wrongfully seized this cargo from a Spanish vessel in 1814 while they were on board their own ship during an authorized cruise as part of their service to the United States Navy. The Supreme Court ruled that although it was true that no formal declaration or notice had been given by Congress at the time when these goods were taken, yet such seizure would be justified under international law if it could be shown to have been made for public use or benefit; thus making it lawful according to principles recognized by all nations. Furthermore, since there is evidence showing that Spain had declared war against Great Britain prior to this incident taking place, then any capture which took place after such declaration would also be considered legal under international law regardless whether Congress has formally declared war itself or not.

In the case of Thirty Hogsheads of Sugar, Adrian B. Bentzon, Claimant v. Boyle and Others, Being the Officers and Crew of the Privateer Comet, Chief Justice Marshall delivered a dissenting opinion in which he argued that privateers are not authorized to capture neutral vessels on suspicion alone. He reasoned that such captures would be contrary to international law as well as US laws because they would violate the rights of neutrals who have done nothing wrong or illegal. Furthermore, Marshall noted that if privateers were allowed to make such captures without any proof or evidence then it could lead to abuse by those in power since there is no way for them to be held accountable for their actions. Finally, he concluded by stating that allowing these types of seizures would ultimately weaken America's standing among other nations due its disregard for international law and treaties concerning neutrality rights.
