Anthony Johns v Crown Equipment Corporation
Attorneys and Parties
Brief Summary
Product liability/design defect in a stand-up industrial forklift and admissibility of expert statistical comparisons and future medical expense testimony.
Allowed defendant’s statistician to compare injury rates from Crown forklifts to a broad federal category of 'industrial truck and tractor operators,' limited plaintiff’s life-care physician’s opinions as speculative and, consequently, curtailed the economist’s damages testimony; jury found no design defect or breach of warranty and verdict entered for defendant.
Judgment for defendant reversed and case remitted for a new trial.
The trial court abused its discretion by admitting defendant’s comparative statistics based on a broad, dissimilar federal category without a showing of substantial similarity, and by excluding/limiting plaintiff’s future medical and economic damages evidence that was supported by competent medical testimony. Frye [test allowing admission of novel scientific evidence only if the underlying principle or technique is generally accepted in the relevant scientific community] was inapplicable.
Background
On December 31, 2018, plaintiff, operating a stand-up forklift designed and distributed by defendant, could not successfully engage either braking mechanism, struck a warehouse support pole, and suffered a severe left leg injury resulting in amputation. He sued in July 2019 alleging defective design and that defendant knew or should have known of dangers in intended use. Before trial, both sides moved in limine regarding experts. The court permitted defendant’s statistician (Marais) to testify; reserved ruling on the scope of plaintiff’s life-care physician (Root) and economist (Thomas) until trial.
Lower Court Decision
After Root testified, the court deemed portions speculative and limited Thomas from costing certain future treatments. The court allowed Marais to compare defendant’s forklift injury rate (from Crown’s voluntary reports) to a federal database rate for 'industrial truck and tractor operators.' The jury found no design defect and no breach of warranty; damages were not reached; judgment entered for defendant.
Appellate Division Reversal
The court held it was proper to allow testimony quantifying injury rates from defendant’s own database (also used by plaintiff’s expert), but it was an abuse of discretion to admit comparisons to the broad federal category because the defendant failed to establish substantial similarity between those accidents and the case at bar. That error went to the central safety issue and was not harmless. Separately, Root’s life-care opinions were based on competent medical knowledge and stated to a reasonable degree of medical certainty; thus, limiting Thomas’s associated cost testimony was an abuse of discretion. The judgment was reversed and a new trial ordered.
Legal Significance
Confirms that comparative accident statistics are admissible only with an adequate foundational showing of substantial similarity; broad industrial categories that mix dissimilar vehicles/conditions are improper. Reinforces that foundational rulings are legal questions for the court, and that rebuttal does not permit otherwise inadmissible evidence. Clarifies that future medical expenses may be presented where a qualified physician provides competent, non-speculative testimony to a reasonable degree of medical certainty, with an economist then quantifying costs.
Use accident data that is closely matched to the product and conditions at issue; overly broad comparative statistics lack foundation and risk reversal. When a life-care physician provides competent, certain opinions, related economic damages should not be excluded; disputes go to weight via competing experts, not admissibility.
