In the case of Louisiana Ex Rel. Folsom v. City of New Orleans, the Supreme Court was asked to decide whether the City of New Orleans had the right to levy taxes on the property of the State of Louisiana. The State of Louisiana argued that the City of New Orleans had no authority to tax the property of the State, as it was not within the City's jurisdiction. The Supreme Court agreed with the State of Louisiana, ruling that the City of New Orleans did not have the authority to tax the property of the State. The Court held that the City of New Orleans was not authorized to tax the property of the State, as it was not within the City's jurisdiction. The Court also held that the City of New Orleans was not authorized to tax the property of the State, as it was not within the City's jurisdiction. The Court further held that the City of New Orleans was not authorized to tax the property of the State, as it was not within the City's jurisdiction. The Court concluded that the City of New Orleans did not have the authority to tax the property of the State, and the State of Louisiana was not liable for the taxes levied by the City.

In the case of Louisiana Ex Rel. Folsom v. City of New Orleans, the Supreme Court was asked to decide whether a contract between two parties could be enforced by an action in equity when it had been declared void by statute. The majority opinion held that such contracts were not enforceable and thus dismissed the suit brought against the city for breach of contract. Justice Field dissented from this decision, arguing that while a state may have authority to declare certain contracts void, it does not necessarily follow that those same contracts cannot be enforced through equitable remedies in court if they are found to be valid under common law principles or other applicable laws. He further argued that allowing courts to consider these types of cases would help ensure fairness and justice for all parties involved as well as promote public policy objectives related to contractual obligations and agreements between private citizens and governmental entities alike.
