A more thorough explanation:

The right to a jury trial is a legal right provided by the Sixth and Seventh Amendments. The Sixth Amendment guarantees the right to a trial by an impartial jury for all criminal prosecutions. The Seventh Amendment guarantees the right to a jury trial for suits in common law if the value in controversy exceeds twenty dollars.

However, the Supreme Court has set legal precedent that excludes petty offenses from the guarantee to a jury trial in federal courts. The court has also made slight changes to certain phrases, such as with "criminal proceeding," to focus on the specific action that necessitates the inclusion of a jury. Additionally, the right to a jury trial is waivable in certain instances, but this differs depending on the jurisdiction.

On the federal level, the Seventh Amendment right to a jury trial applies to civil cases. However, states are not required to guarantee civil trials under the Seventh Amendment, though most states have the right to a civil trial in specific cases to some degree in their state constitutions.

• In a criminal case, the accused has the right to a trial by an impartial jury of the state and district in which the individual allegedly committed a crime. For example, if someone is accused of committing a crime in California, they have the right to a trial by a jury of their peers in California.
• In a civil case, if the value in controversy exceeds twenty dollars, the right to a jury trial is preserved. For example, if someone sues another person for damages exceeding twenty dollars, they have the right to a trial by a jury.

These examples illustrate how the right to a jury trial applies in both criminal and civil cases and how it is guaranteed by the Sixth and Seventh Amendments. They also show how the value in controversy is a determining factor in whether the right to a jury trial is preserved in civil cases.
