Final answer:
The final decision or determination of a commission is reviewable by the U.S. Supreme Court after all other avenues of appeal have been exhausted. The U.S. Supreme Court serves as the court of last resort with both original and appellate jurisdiction to decide on matters of law and fact, including the review of commission decisions.
Step-by-step explanation:
Any final decision or determination of a commission, such as one issued by federal regulatory agencies, may ultimately be subject to judicial review by higher courts. In the United States, the apex of the judicial system is the U.S. Supreme Court. This means that after all other avenues of appeal have been exhausted, parties may petition the U.S. Supreme Court to review the decision. The U.S. Supreme Court holds both original and appellate jurisdiction, being the 'court of last resort' and providing the final opportunity for remedy and resolution of a case.
According to U.S. law, specifically under Section 344(b) Title 28 of the United States Code Annotated (USCA), the Supreme Court has the authority and jurisdiction to review final judgments of state supreme courts, if there is a relevant federal question, such as an issue of constitutional law under the 'Due Process Clause'. In matters of commission decisions, the appropriate course of action generally involves moving through the hierarchy of courts before reaching the Supreme Court.
It is essential to note that the U.S. Supreme Court has original jurisdiction in cases involving ambassadors, public ministers, consuls, and when a state is a party. However, in all other cases that have been previously adjudicated by lower courts, the Supreme Court wields appellate jurisdiction, which means it can review matters of both law and fact, subject to exceptions and regulations set by Congress.
