Summary
Plaintiff's counsel in a Fair Labor Standards Act collective action brought on behalf of Eagle County airport rescue and firefighting personnel filed a Complaint that relied on an outdated regulatory framework: the pre-2011 "20 percent rule" from 29 C.F.R. § 553.212, which the Department of Labor amended out of the firefighter exemption regulations in 2011. The court found the misstatement of governing law consistent with uncritical reliance on generative AI research and imposed monetary sanctions covering fees and costs incurred by the county in responding to the defective pleading.

- Unspecified generative AI
- Sanction amount:
- $28,000
What sanction did the court impose?
Court ordered counsel to pay $28,000 in fees and costs to Eagle County. The order required corrected briefing under the current 29 C.F.R. § 553.215 framework and warned that further reliance on superseded authority would draw escalated sanctions.
Why does Lewis v. Eagle County Government matter for law firms using AI?
For managing partners, Lewis is a reminder that AI-induced errors are not limited to fabricated citations. Reliance on a regulation that was amended out of the C.F.R. in 2011, in a 2025 federal complaint, is the kind of mistake a competent associate would catch on a first read but that a model trained on stale secondary sources will reproduce confidently. The compliance question is whether the firm’s verification workflow catches superseded authority, not just nonexistent cases.
