Final answer:
Cases typically start at the state or local level and can move to federal courts through appeals involving federal law or the U.S. Constitution.
Step-by-step explanation:
The subject of this question revolves around federal jurisdiction and how a federal court presides over issues dealing with federal matters.
Your statement is partially correct; federal courts can hear federal questions, but the $75,000 amount in dispute does not apply to all cases, mostly relating to civil disputes that include this monetary threshold.
Typically, cases begin at the state or local level, then can move to the federal system through appeals depending on the involvement of federal law or Constitutional issues.
These cases generally need to exhaust all appeal avenues within the state court system first.
There is a variety of federal courts with a range of jurisdiction.
One noticeable characteristic is that no district court crosses state lines, and each one is overseen by a single judge. Whether the cases needs to be heard by a jury or a judge alone can vary, especially in civil disputes involving lesser sums of money, which could be heard by a small claims court instead.
