Final answer:
The vast majority of cases that reach the Supreme Court come from the circuit courts or the U.S. courts of appeals after originating in the federal district courts. They can also come from state supreme courts when there is a substantive federal question in the case.
Step-by-step explanation:
The vast majority of cases that reach the Supreme Court come from two primary pathways. The vast majority of cases that reach the Supreme Court come from the circuit courts or the U.S. courts of appeals after originating in the federal district courts. They can also come from state supreme courts when there is a substantive federal question in the case.
Firstly, they come from the circuit courts or the U.S. courts of appeals after originating in the federal district courts. Secondly, they come from state supreme courts when there is a substantive federal question in the case. Once the Court agrees to hear a case, the attorneys for the respondents and petitioners prepare and submit briefs that present the arguments and facts from relevant precedents.
