Otis v. Watkins was a case heard by the United States Supreme Court in 1815. The dispute involved two men, Otis and Watkins, who had been engaged in a business partnership for several years prior to the case being brought before the court. At issue was whether or not Otis could be held liable for debts incurred during their partnership that were solely attributable to Watkins' actions. The court ultimately ruled in favor of Otis, finding that he should not be held responsible for any debt resulting from his partner's misconduct as it would constitute an unfair burden on him and violate basic principles of justice and equity. This ruling established important precedent regarding partnerships between individuals which is still relevant today when determining liability among partners within a business arrangement.

In the case of Otis v. Watkins, Chief Justice Marshall delivered a dissenting opinion in which he argued that Congress had no authority to pass an act allowing for the recovery of damages from a private individual who wrongfully seized another's property during wartime. He reasoned that such an action was not within the scope of congressional power and thus could not be enforced by federal courts. Furthermore, he argued that it would be unjust to allow individuals to recover damages when they were acting under orders from their government or superior officers during war time as this would create a disincentive for military service and undermine public confidence in those serving in the armed forces. Ultimately, Chief Justice Marshall concluded that any attempt by Congress to provide relief through civil suits against individuals should only occur after peace has been declared and all hostilities have ceased.
