4:23-cv-00330
E.D. Mo.Feb 20, 2025Background
- TNT Amusements and Torch Electronics are competitors in the Missouri amusement device market. TNT leases traditional arcade games, while Torch leases "no-chance" gaming devices.
- The core dispute is whether Torch’s machines are illegal slot machines under Missouri law, contingent on whether they involve an element of chance.
- Both parties each retained expert witnesses (Friedman for TNT, Farley for Torch) to testify about how Torch’s devices operate technologically regarding randomization and chance.
- Both experts ultimately agreed on the technical functioning: games select a random starting point in a finite outcome pool, then outcomes are delivered in a fixed sequence; display symbols are randomly mapped to outcomes.
- Both parties filed motions to exclude the opposing expert’s testimony under Federal Rule of Evidence 702, centering on qualifications, methodology, and admissibility.
- The court’s role at this stage is to determine the admissibility of expert opinions—not the ultimate legality of Torch’s devices.
Issues
| Issue | Plaintiff's Argument (TNT/Friedman) | Defendant's Argument (Torch/Farley) | Held |
|---|---|---|---|
| Whether Friedman’s expert opinions should be excluded | Friedman is qualified and his technical findings accurate | Friedman is unqualified on Missouri law; initial analysis improper | Friedman is qualified; any initial errors are moot; motion denied |
| Whether Farley’s expert opinions should be excluded | Farley’s reliance on staff yielded unreliable methodology | Farley is qualified; challenges go to weight not admissibility | Farley is qualified; issues affect credibility, not admissibility |
| If experts may opine on legality under Missouri gambling law | Friedman should not opine on ultimate legality | Farley should not opine on ultimate legality | Experts may not testify as to legal conclusions |
| Relevance of random functions to definition of “chance” | Random elements affect legal analysis | Such randomization is irrelevant to outcome or legality | Relevance is legal issue for court, not experts; no such opinions |
Key Cases Cited
- Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579 (trial judges serve as gatekeepers, screening expert testimony for relevance and reliability)
- Kumho Tire Co. v. Carmichael, 526 U.S. 137 (flexibility in reliability testing for expert evidence)
- Russell v. Whirlpool Corp., 702 F.3d 450 (main purpose of Daubert exclusion is to prevent juries being swayed by dubious scientific testimony)
- Barrett v. Rhodia, Inc., 606 F.3d 975 (admissibility requires expert's methodology to be scientifically valid and properly applied)
- DiCarlo v. Keller Ladders, Inc., 211 F.3d 465 (expert bias and credibility concerns go to the weight, not admissibility, of the testimony)
