Federal court jurisdiction is limited to certain kinds of cases listed in the Constitution. For the most part, federal courts hear cases in which the United States is a party, cases involving violations of the Constitution or federal law, crimes on federal land, and bankruptcy cases. 

The federal civil litigation system in particular is filled with a variety of business-related disputes. These may include actions concerning contracts, copyrights, trademark infringement, antitrust and unfair competition, employment discrimination, and environmental issues.

A civil petit jury is typically made up of 6 to 12 persons. In a civil case, the role of the jury is to listen to the evidence presented at a trial, to decide whether the defendant injured the plaintiff or otherwise failed to fulfill a legal duty to the plaintiff, and to determine what the compensation or penalty should be.

A criminal petit jury is usually made up of 12 members. Criminal juries decide whether the defendant committed the crime as charged. The sentence usually is set by a judge.

Verdicts in both civil and criminal cases must be unanimous, although the parties in a civil case may agree to a non-unanimous verdict. A jury's deliberations are conducted in private, out of sight and hearing of the judge, litigants, witnesses, and others in the courtroom.
