A limit not placed on the supreme court is that they get to choice which cases they want to hear. The supreme court holds the full say so in which cases they choice and they only hear few cases throughout the year.
The Supreme Court's power is restricted by several limits: first, it can only hear cases that come before it, as it lacks the authority to initiate cases. Second, its decisions can be overturned by constitutional amendments, which require significant political consensus. Third, the Court's jurisdiction is constrained by laws passed by Congress, which can also regulate the types of cases the Court can hear. Lastly, the justices themselves can be removed through impeachment, although this is rare and requires a significant political process.
This is admittedly an educated guess and may be applicable only in the US: But I believe the answer would be Municipal Courts or County-level court systems probably hear the most cases due simply to the sheer number of misdemeanor and traffic cases that are heard each day.
No, the Supreme Court does not only hear mail fraud cases. It has the authority to hear a wide range of cases, including those involving constitutional issues, federal laws, and disputes between states. The Court typically hears cases that involve significant legal principles or conflicts among lower courts. Mail fraud cases may come before the Supreme Court if they raise important legal questions, but they represent just a small fraction of the Court's overall docket.
A review court is one which has appellate jurisdiction rather original jurisdiction over cases. Courts with original jurisdiction hear cases at the trial level only. Courts with appellate jurisdiction cannot hear trials. They only review decisions made by trial courts to ensure that those decisions were correctly rendered.
