42 F.4th 962
8th Cir.2022Background
- Class action by commercial student truck drivers against Werner Enterprises and Drivers Management alleging unpaid off-duty short breaks and sleeper-berth time in an 8-week training program.
- After a three-day trial, jury awarded plaintiffs $779,127 on short-break claims; district court had allowed a belated expert report by amending scheduling order.
- This court previously vacated the judgment in Petrone v. Werner Enters., 940 F.3d 425 (8th Cir. 2019), holding the district court abused its Rule 16(b) discretion in permitting the untimely expert disclosure and that the error was not harmless.
- On remand plaintiffs moved for a new trial, sought to admit the untimely expert under Rule 37(c)(1), or else a court‑appointed expert under Rule 706; defendants moved for judgment on the mandate.
- The district court granted defendants’ motion, entered judgment for defendants, and dismissed with prejudice reasoning plaintiffs could not prove damages absent the excluded expert and that Rule 1006 summaries would not suffice.
- The Court of Appeals vacated that dismissal, holding the district court abused its discretion by failing to perform the required Rule 37(c)(1) analysis and by not considering plaintiffs’ Rule 706 request, but agreed Rule 1006 summaries likely could not prove damages without expert help.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the appellate mandate required entry of judgment for defendants on remand | Mandate did not compel judgment; district court could proceed and exercise discretion | Mandate’s statement that expert issue was dispositive means dismissal for defendants is required | Held: Mandate did not direct judgment for defendants; remand permitted further proceedings |
| Whether district court had to perform Rule 37(c)(1) analysis when plaintiffs sought to use the untimely expert on remand | Plaintiffs argued Rule 37(c)(1) applies when they sought to use the late expert in a new-trial motion and court had to analyze sanctions/admission | Defendants argued dismissal followed from the prior mandate and expert must be excluded | Held: Court abused discretion by not conducting the Rule 37(c)(1) analysis when plaintiffs moved to use the late expert |
| Whether the court had to consider appointing a Rule 706 court‑appointed expert | Plaintiffs requested a Rule 706 expert as alternative relief and argued court must consider it | Defendants treated appointment as unnecessary and relied on mandate dismissal | Held: Court abused discretion by failing to consider or decide plaintiffs’ Rule 706 request |
| Whether plaintiffs could prove damages without expert testimony using Rule 1006 summaries of pay/time records | Plaintiffs said voluminous payroll/time records could be summarized under Rule 1006 and the jury could calculate damages | Defendants said the calculations were complex and required expert analysis; Rule 1006 inappropriate | Held: Court correctly concluded Rule 1006 summaries would not suffice because the damages computation was complex and required expert assistance |
