Shared proof in class actions
United Airlines v. Kincannon
In brief
- Where it stands
- Dismissed
Petition denied. Justice Kavanaugh would grant the petition for a writ of certiorari.
- What it’s about
- United Airlines asked the Supreme Court to review a Fifth Circuit ruling that found commonality and predominance based on similar evidence plaintiffs said a jury could accept, even though liability might differ among class members.
- Who it affects
- The Fifth Circuit ruling remains in place in this case, but the Supreme Court's refusal to hear it does not approve the ruling's reasoning.
Summary: written with AI from the case record.
What it's about
The Supreme Court refused to hear the case (denied review), so it did not decide that legal question.
The dispute asked whether shared questions and evidence are enough to let people bring claims together when responsibility may still depend on each person.
Question presented
In assessing commonality and predominance under Rule 23, is it sufficient that plaintiffs have a common theory and evidence that a jury could credit, even where rejecting that theory and evidence would not result in a classwide loss, but in individual liability determinations that differ across class members?
