COST COSTCO WHOLESALE CORP /NEW
Price Chart
Executive Summary
The Illinois Appellate Court affirmed summary judgment for Costco in a slip-and-fall negligence case, holding that a quarter-inch pavement deviation in its parking lot was a de minimis defect that did not trigger a duty to repair or warn. The ruling eliminates any liability exposure from this individual claim and does not create adverse precedent for Costco.
Court Ruling Details
Actionable Insight
This ruling removes a minor litigation overhang and confirms Costco's low tort liability risk profile. No material financial impact — the case was always below 0.1% of market cap. Monitor for any future class-action or pattern litigation, but this isolated ruling has no read-through for the stock.
Key Facts
- Plaintiff Janet Drobick fell in Costco parking lot; alleged defect was a ¼-inch pavement deviation.
- Trial court granted summary judgment for Costco under the de minimis doctrine; appellate court affirmed.
- Illinois courts generally set the de minimis threshold at two inches; a ¼-inch deviation is far below that.

- The opinion was filed under Supreme Court Rule 23 and is not precedential except in limited circumstances.
Financial Impact
No damages awarded; individual slip-and-fall claim with trivial exposure relative to Costco's $419.7B market cap.
Risk Factors
- No material risk identified from this ruling; the de minimis doctrine is well-established in Illinois.
