Montalet v. Murra was a United States Supreme Court case that dealt with the issue of whether or not an executor could be held liable for debts incurred by the deceased prior to their death. The court ruled in favor of Montalet, finding that Murra had no right to demand payment from him as he was only responsible for settling the estate and distributing assets according to law. This decision established precedent which has since been followed in similar cases, holding that an executor is not personally liable for any debt incurred by the decedent before his death unless it can be proven otherwise through legal action. Furthermore, this ruling also serves as a reminder of how important it is to properly manage one's finances while alive so as not to leave behind any outstanding obligations upon passing away.

In Montalet v. Murra, the Supreme Court was asked to decide whether a contract between two parties could be enforced when it had been made in violation of an existing law. The majority opinion held that the contract should not be enforced because it violated public policy and would encourage similar violations in the future. However, Justice Paterson dissented from this decision and argued that contracts are sacred agreements between individuals which should not be interfered with by government or courts unless there is clear evidence of fraud or illegality on behalf of one party. He further argued that if such contracts were allowed to stand then they would serve as precedents for other cases where no fraud or illegality existed, thus undermining public confidence in private contractual arrangements.
