The Brig Alberta and Cargo, (Brosquet, Claimant,) v. Blas Moran, Libellant was a case heard by the United States Supreme Court in 1815. The case involved a dispute between Brosquet and Moran over ownership of cargo on board the Brig Alberta which had been seized by French privateers during an armed conflict with Spain. Brosquet claimed that he owned the cargo while Moran argued that it belonged to him as part of his estate from his deceased father-in-law who had purchased it before its seizure. The court found in favor of Brosquet based on evidence presented at trial showing that he was indeed the rightful owner of the cargo due to having paid for it prior to its seizure by French privateers. This decision established important precedent regarding property rights during times of war or other conflicts involving foreign nations and their citizens within U.S borders

In the case of The Brig Alberta and Cargo v. Blas Moran, Libellant, Chief Justice Marshall delivered a dissenting opinion in which he argued that the court should not have dismissed the appeal on procedural grounds. He believed that it was necessary to consider whether or not there had been sufficient evidence presented by both parties to support their respective claims before dismissing an appeal for lack of jurisdiction. In this particular case, he felt that there had been enough evidence provided by both sides to merit further consideration from the court and thus concluded his dissent with a call for more thorough examination into all aspects of the dispute between them. Ultimately, however, his view did not prevail as majority ruled against him and upheld dismissal on procedural grounds without considering any other factors involved in this case.
