Final answer:
Cases that present a federal issue in state court can be heard by the Supreme Court of the United States, particularly if they involve a federal question like constitutional or federal law issues.
Step-by-step explanation:
Cases that present a federal issue in state court can make it to the Supreme Court of the United States. The Court primarily hears cases on appeal that involve a federal question, such as issues related to the U.S. Constitution, federal laws, or treaties. Cases also reach the Supreme Court when there is a constitutional question or conflicting interpretations of a law by lower courts.
Specifically, the Supreme Court has original jurisdiction in cases involving states or ambassadors, but acts as an appellate court for all other federal issues. Issues of federal law may originate in state courts before moving to the federal side, and a case from a state court can enter the federal system on appeal but only if it involves a federal law or question.
