Summary: written with AI from the case record.

What it's about
She says they did so without checking conflicting evidence, considering less severe penalties, or finding that she acted intentionally or harmed the other side.
The petition challenged the path from disputed discovery issues to excluding expert testimony and ending Stevens-Reynolds's insurance case on causation grounds.
Question presented
1. Whether federal courts may exclude expert testimony essential to a plaintiffs case based on disputed discovery violations without making findings regarding willfulness, bad faith, or prejudice, and without considering less drastic sanctions, thereby effectively determining the merits through procedural rulings in violation of the Due Process Clause. 2. Whether federal district courts may grant summary judgment on technical causation issues requiring expert testimony after excluding such testimony on procedural grounds, creating a procedural sequence that denies meaningful opportunity to be heard. 3. Whether courts have a duty to investigate claims of discovery non-compliance when the record contains contradictory evidence, including documentary proof of compliance, before imposing case-ending sanctions.
