987 N.W.2d 398
S.D.2023Background
- On Oct. 26, 2016 Beverly Winkler rear-ended Robert Lamb’s 1982 Versatile tractor (towing a John Deere finisher) on US-212; Beverly died and her BAC was 0.16. Circuit court granted partial summary judgment that Beverly was negligent per se.
- The tractor was driven ~250 feet after impact; the hitch pin was sheared, the finisher sustained visible damage, and the tractor was later towed to Lambs’ farm and not moved again during litigation.
- Lambs purchased replacement tractor and finisher in early 2017; they did not obtain a formal inspection or written repair estimates for the damaged tractor, citing cost, timing, and parts availability.
- At bench trial Lambs relied mainly on Robert’s opinion of the tractor’s pre-collision value ($39,000), verbal repair-cost recollections, and testimony from a diesel mechanic (Merrow) who provided broad repair-cost ranges but no detailed inspection.
- The circuit court found some tractor components were damaged (batteries, articulating joint/pivot, hitch pin) but declined to award any tractor-damage recovery because Lambs failed to prove diminution in value or repair costs with reasonable certainty.
- The Supreme Court affirmed in part, reversed in part: it ordered remand solely to award $700 for battery replacement, upheld denial of damages for articulation repair and hitch pin, and affirmed the court’s refusal to award total-destruction/diminution recovery absent adequate proof.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether court erred by awarding no damages for tractor (diminution or total loss) | Lambs: owner’s valuation and estimated repair costs show repair > market value, so tractor effectively destroyed; ask $39,000 minus $2,500 salvage | Winkler: estimates speculative; no inspection or written bids; testimony was controverted on cross-examination | Court: affirmed — Lambs failed to prove diminution or total loss with reasonable certainty absent inspection/evidence |
| Whether uncontroverted owner testimony binds the factfinder | Lambs: Robert’s testimony was uncontradicted and should be taken as established | Winkler: cross-examination controverted Robert; burden on Lambs to prove damages | Held: Owner testimony may inform value but is not binding; cross-examination can render it controverted |
| Whether court must award proven repair costs for observable damage (battery, pivot, hitch pin) | Lambs: some repairs (battery, pivot, hitch pin) were proven and court should award repair costs shown in findings | Winkler: costs for pivot and hitch pin not proven with specificity; awarding would be speculative | Held: Award $700 for battery (uncontroverted). Denied pivot ($7,400) and hitch pin—insufficient, speculative evidence |
| Standard for damages proof (reasonable certainty vs. speculation) | Lambs: owner’s estimates and expert ranges were sufficient | Winkler: speculative ranges do not meet reasonable-certainty rule | Held: Damages must be shown with reasonable certainty; factfinder may reject speculative estimates—court’s findings not clearly erroneous |
