In determining which case the Supreme Court would most likely choose to hear, we should consider factors such as the significance of the legal issues involved, conflicting rulings in lower courts, and the urgency of the case.
A. Case 1 presents a significant constitutional issue involving the denial of Fourteenth Amendment protections to a minority group, with different rulings from US Circuit Courts creating a split in the interpretation of federal constitutional law. This is a compelling reason for the Supreme Court to hear the case, as they often take cases that address conflicting rulings to ensure consistent application of federal law.
B. Case 2 deals with a state constitutional issue that has already been resolved by the state supreme court. The Supreme Court typically focuses on issues of federal law or how state laws may conflict with the Constitution, making it less likely they would take this case.
C. Case 3 involves a defendant's Fourth Amendment rights. While the issues of criminal procedure and constitutional rights are significant, the decision has already been made by the district court, resulting in a retrial. It may not be urgent for the Supreme Court to intervene at this point since a remedy has been established.
D. Case 4, while addressing a controversial state law and the potential for harm to the public, has not yet been heard by lower courts. The Supreme Court generally prefers to allow lower courts to address legal issues before they take up a case.
Considering these factors, A. Case 1 would likely be the case the Supreme Court would most choose to hear due to the constitutional implications, the significance of protecting minority rights, and the conflicting rulings among circuit courts.
