Most federal cases begin in the U.S. District Courts, which are the general trial courts of the federal court system. Each state has at least one district court, and there are 94 federal judicial districts in total. These courts handle a wide range of cases, including civil and criminal matters involving federal law. If parties wish to appeal a decision from a district court, they can take their case to the U.S. Court of Appeals.
Most federal cases begin in the district courts.
Yes, that is the level at which most federal cases are first introduced.
State court cases begin in trial courts. They graduate up to the state level if one of the litigants is not satisfied with the decision of the lower court.
Most federal criminal cases are tried in US District Court.
In most cases I have read the civil cases heard at the Federal level are cases that directly question someone's rights and apply to a large number of people. The cases heard at a local level can also be promoted to Federal cases. For example if you have a property dispute with your neighbor it will not go to federal court; however, if you have a court that disputes whether its legal for you to carry a concealed weapon or practice free speech you could proceed to the Federal Court.
Generally, federal criminal cases are tried in US District Court.
Federal.
The U.S. District Courts handle the most federal cases, as they are the general trial courts of the federal court system. These courts have jurisdiction over a wide range of civil and criminal cases, including those involving federal law, constitutional issues, and disputes between states or citizens of different states. Additionally, the U.S. Courts of Appeals hear appeals from District Court decisions, but the volume of cases is significantly higher at the District Court level.
Federal appellate cases
State courts hear far more cases than federal courts.
Federal trial courts almost always have original jurisdiction in the federal system.
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.
