Final answer:
Federal courts have jurisdiction over cases involving federal law and disputes between different states or residents of different states. Presidents prefer federal judges who share their views for ideological consistency, but appointed judges have lifetime tenure, making their decisions independent. The Supreme Court hears cases on appeal and decides them after reviewing documents, oral arguments, and discussions among justices.
Step-by-step explanation:
Jurisdiction of Federal Courts
The two main factors that give federal courts jurisdiction over a case are the type of laws involved and the parties in the case. Federal courts have jurisdiction to decide cases involving federal law, including disputes between states, and disputes between residents of different states. As an example, if a case involves the interpretation of a federal statute or the U.S. Constitution, federal courts would have jurisdiction. Another example is a case where citizens of different states are in a legal dispute over a contract, and the amount in question exceeds $75,000.
Presidential Preferences for Federal Judges
Presidents prefer federal judges who align with their views because they hope their appointees will make rulings consistent with their own ideological leanings. Judges and justices serve lifetime appointments, which allows them the freedom to make decisions without political pressure, but a president might appoint a judge with the expectation that they will support certain legal interpretations or policy perspectives. It's worth noting that judges, once appointed, may still make decisions that do not always reflect the expectations of the appointing president.
Supreme Court Case Procedure
When a case reaches the Supreme Court, it is usually heard after the case has gone through the lower federal courts (district and appellate courts) or state supreme courts if a federal question is involved. The Court reviews the documents from previous trials, listens to oral arguments, and reads briefs from various interested parties before the justices meet to discuss and vote on the case. The decision process is influenced by internal and external players, like law clerks and the solicitor general, set precedent, and is ultimately based on interpretations of the Constitution and law.
