Armour was decided by the Supreme Court of the United States on January 23, 1851, in a 9-0 ruling.

The case originated from the Louisiana U.S.

Circuit Court, where McGill filed a petition against Armour, who was the executrix of the will of James Armour.

In her petition, McGill claimed to be a creditor of the estate, but the petition only stated that she was shown to be a creditor in the accounts of the state court that had jurisdiction over the estate.

The circuit court sustained Armour's exceptions and dismissed McGill's suit, ruling in favor of the defendant.

McGill then appealed the case to the Supreme Court, which affirmed the ruling of the lower court in its 9-0 decision.

The Supreme Court's decision was based on the fact that McGill's petition did not contain sufficient allegations to establish her status as a creditor of the estate.

The case is significant because it demonstrates the importance of proper pleading and the need for plaintiffs to clearly establish their legal standing in a case.

The Supreme Court's unanimous decision in this case suggests that the legal principles involved were well-established at the time.

The case provides insight into the legal process and procedures governing the administration of estates in the mid-19th century United States.

The outcome of the case highlights the challenges that creditors faced in asserting their claims against the estates of deceased individuals.

The case is an example of the complex and technical nature of probate law, which often requires careful attention to formal legal requirements.

The Supreme Court's ruling in McGill v.

Armour has been cited in numerous subsequent cases, underscoring its significance in the development of American jurisprudence.
