Crimes that violate both state and Federal Laws can be tried in either state or federal court. Frequently, they are tried in both.
If the trafficking crosses state boundaries, it will be tried in the federal system. If not, it usually depends on whether a federal agent or a state agent performed the arrest and if you are being charged with a state statute or a federal code violation.
Either the state or federal court.
Under some situations, a case involving a person from out of state can be tried in a Federal Court according to a state law. While state law never supersedes Federal law, a lawyer can bring up a case from state law that might have bearing on a Federal Case. The way the United States Supreme Court ruled on that state case would affect Federal Law and could influence the federal court.
A federal case is tried in a federal branch circuit court. States typically have several of these courts that will try all federal cases from a certain region in a state.
An easy answer might be that a federal case is one that is tried in federal courts and a state case is one that is tried in state courts, but it is not that simple. A federal case is one which involves enforcement of federal statutes or the Constitution or civil cases under the so-called diversity jurisdiction of the courts. Diversity jurisdiction allows issues that would ordinarily be state cases to be tried in federal courts if the parties are located in different states and the amount in controversy exceeds a statutorily fixed amount. One might say that this is simply a state case in a federal court, but it is more correct to call it a federal case since federal law created federal diversity jurisdiction and since it is being tried in a federal court. A state case is one which involves enforcement of state statutes or case law (like personal injury, contract and state criminal offenses). Sometimes federal issues are raised in state courts. Nothing prohibits a party in a state court from raising federal constitutional issues. In fact it is common, such as when in a state criminal trial, the accused alleges his federal constitutional rights have been violated. Examples are demands to exclude evidence that has been obtaine through an allegedly unreasonable search and seizure, or that a new trial should be had because the defendant was denied competent counsel and other protected rights. The mere raising of a federal issue does not require it to be heard in a federal court.
A federal question case takes place when the alleged plaintiff is charged with a violation against the United States Constitution. It can also a violation against federal law or a treaty which the United States is party to.
In general, the answer is that you cannot be tried for the same crime twice. You can be tried in federal court on the same facts under a different theory if you have been acquitted in state court. Every case is different. If you need information on a state or federal criminal case, seek information from your attorney or from an attorney at your local public defender's office.
it doesn't happen, US court is perfect.
With one exception, a case that raises only state related issues cannot be tried in federal courts, because federal court jurisdiction is limited to cases that raise federal questions. The only time a case that raises only state issues can be filed in federal court is where the case qualifies for federal diversity jurisdiction, i.e. both parties reside in different states and the amount in controversy exceeds $75,000. Federal diversity jurisdiction parameters are fixed by a federal statute.
A federal case is any case about the violation of a federal law such as federal tax evasion, desertion of the US military, or international drug smuggling. Some crimes that would create state cases (non-federal cases) include traffic violations and state tax evasion.
Under most circumstances, murder would be tried in a state court; if the defendant is in the military, it may be tried in a military court (federal). If the crime was committed as part of another federal crime or on federal property, the case would appear before a federal court.Under certain circumstances, the defendant (and only the defendant) has the option to exercise federal courts' removal jurisdiction to move his or her case from state to federal court (as outlined in 28 U.S.C. § 1441).
It would be a Federal crime and would be tried in a United States District Court.
