A new trial on limited issues is allowed under the Seventh Amendment only when the issues to be retried are separate and distinct from those resolved by the first jury. When the plaintiff sues for intentional infliction of emotional distress, damages are intertwined with liability because recovery is allowed only when the tortious conduct caused severe emotional distress. Here, however, the plaintiff sued for emotional distress caused by the physical injury she suffered when shot in the head by a policeman. In that situation, since it was the physical injury that caused the emotional distress, not the defendant’s conduct, liability was separate from damages, and the district court correctly granted a new trial on damages only.
