In Humiston v. Stainthorp, the United States Supreme Court considered a case involving an agreement between two parties to purchase and sell land in New York State. The plaintiff, Humiston, had agreed to buy the land from defendant Stainthorp for $2,000 but failed to pay on time. As a result of this breach of contract by Humiston, Stainthorp sued him for damages in the amount of $1,500 plus interest and costs associated with bringing suit against him. The Supreme Court held that although there was no express provision in the contract regarding payment terms or interest rates due upon late payments made by either party involved in such transactions; it is implied that if one party fails to fulfill their contractual obligations then they are liable for any losses incurred as a result thereof including reasonable attorney fees and court costs expended by other contracting parties seeking redress through legal action. Furthermore, since both parties were aware of prevailing market conditions at the time when entering into said agreement; it was determined that 6% per annum should be applied as an appropriate rate of interest due on overdue payments owed under said contract which would have been fair compensation given those circumstances existing at that particular juncture within society's commercial framework during its era

In Humiston v. Stainthorp, the Supreme Court was tasked with determining whether a contract between two parties could be enforced when one of them had died before it was fully executed. The majority opinion held that the contract should not be enforced because it had not been completed by both parties and thus did not meet all of the requirements for a valid agreement under state law. Justice Field dissented from this decision, arguing that contracts are binding upon death and should only be voided if they were incomplete or invalid at the time of death. He argued that allowing such agreements to stand would encourage people to enter into contracts knowing their obligations will still remain even after their deaths, which he believed would benefit society as a whole by promoting fair dealing among individuals in commercial transactions.
