Amendment History
(Amended April 30, 2007, effective December 1, 2007.)
Plain-English Summary
Rule 38 is about claiming a jury; Rule 39 is about what happens next. When a jury has been properly demanded, the trial on those issues is by jury — unless the parties stipulate to a bench trial, or the court finds that there is no federal right to a jury on some or all of the issues.
If no jury is demanded, the court tries the issues. Even then, the court has flexibility: on an issue not triable of right by a jury, it may try the issue with an advisory jury, or — with the parties’ consent — try it with a jury whose verdict has the same effect as if a jury had been demanded as of right. The rule keeps the line between jury and bench trials clear while leaving room for the court to manage mixed cases.
Frequently Asked Questions
What happens after a jury is demanded under Rule 38?
Rule 39 sends the demanded issues to a jury unless the parties stipulate otherwise or the court finds there is no jury right; issues without a jury are tried to the court.
What is an advisory jury?
A jury the court may empanel on an issue not triable of right by a jury; its verdict advises the court, which remains responsible for the decision (Rule 39(c)).
