Plain-English summary
Court will weigh when judicial estoppel bars a party who changed positions
The Supreme Court will decide how and when the equitable doctrine of judicial estoppel applies to parties who change positions in litigation. The case, Keathley v. Buddy Ayers Construction, was argued March 24, 2026, and asks whether judicial estoppel requires deliberate misconduct or can apply more broadly.
Why this matters
The ruling will affect when judges can block a party from asserting a position that conflicts with one the party previously took in court. That influences fairness in litigation, how lawyers advise clients, and how parties present or change legal positions over time.
Who may feel it
- Civil litigants and their lawyers
- Federal and state courts that apply judicial estoppel
- Businesses involved in multi-forum or multi-stage litigation
- Government parties when participating in litigation
Key questions
- Does judicial estoppel apply only when a party deliberately misled a court, or can it be applied in the absence of deliberate misconduct?
- What showing must a party make to trigger judicial estoppel—intentional deception, or a lesser standard like negligence or inconsistency alone?
