- In 2019, Dennis secured a defense verdict in a fraud matter on behalf of a national motor vehicle distributor. Plaintiff claimed that the distributor failed to disclose an alleged defect which could cause a fire in a model series of passenger vehicles which ultimately led to a recall. After a two week jury trial in the Allegheny County (Pennsylvania) Court of Common Pleas, the jury returned a verdict in favor of the distributor.
- In 2019, Dennis secured summary judgment on behalf of an international commercial vehicle manufacturer. Plaintiff alleged defects in the vehicle caused transmission issues which impacted the vehicle’s operation. Despite multiple dealer repair attempts, plaintiff claimed these conditions continued to plague the vehicle. After extensive briefing, the trial court granted Dennis’ Motion and dismissed plaintiff’s Complaint.
- In 2019, Dennis secured another dismissal on behalf of a national manufacturer of solvents, removers, fuels and cleaning products. The case arose out of the plaintiff’s alleged use of paint thinners and related products while in Pennsylvania. After being diagnosed with a form of leukemia, plaintiff sued various product manufacturers and their suppliers in the Philadelphia Court of Common Pleas, alleging his leukemia was caused by exposure to benzene from the defendants’ products. Plaintiff argued jurisdiction over the nonresident defendants was appropriate because his purported exposure to their products occurred within the state. The Eckert team successfully convinced the court to focus on the absence of evidence linking the client to Pennsylvania, and to rule that the plaintiff’s alleged use of the client’s product in Pennsylvania, without more, was insufficient to subject the client to jurisdiction in the Commonwealth.
- In 2017, Dennis secured a dismissal of all claims against a national manufacturer of solvents, removers, fuels and cleaning products. Plaintiff alleged he developed cancer as a result of working with the client’s products. Because the plaintiff’s alleged exposure occurred outside of Pennsylvania, the Eckert Seamans team moved to dismiss plaintiff’s claims for a lack of personal jurisdiction. After detailed discovery and a hearing before the trial court, the court agreed that Dennis’ client was not subject to personal jurisdiction in Pennsylvania and dismissed plaintiff’s Complaint.
- In 2015, Dennis secured summary judgment for a national motorcycle manufacturer. Plaintiff alleged that the motorcycle suffered from defects that impacted the ability to safely operate the motorcycle. Dennis successfully argued for a dismissal of the case based upon plaintiff’s failure to preserve critical evidence.
- In 2014, Dennis secured a defense verdict at trial for a national motorcycle manufacturer. Plaintiff alleged defects in the motorcycle caused excessive oil leaks which impacted the motorcycle’s operation. Despite multiple dealer repair attempts, plaintiff claimed these conditions continued to plague the motorcycle. The jury found in favor of Dennis’ client at the conclusion of the case.
- In 2013, Dennis successfully argued an appeal before the Pennsylvania Superior Court, Pennsylvania’s intermediate appellate court, on behalf of multiple motor vehicle manufacturers concerning the ability of a consumer to recover attorney’s fees in matters resolved through an Independent Dispute Settlement Procedure. The panel ruled in favor of the manufacturers, affirming the trial court’s decision granting summary judgment to the manufacturers on the issue.
- In 2012, Dennis secured summary judgment for an international automotive manufacturer on plaintiff’s product liability claims. In its written decision, the trial court found that plaintiff had offered no credible expert opinion to support a theory of product defect. The decision was affirmed on appeal by the Appellate Division of the New Jersey Superior Court.
- In 2010, Dennis obtained a defense verdict at trial on behalf of an international motor vehicle manufacturer. Plaintiff, the vehicle owner, asserted the vehicle unintendedly accelerated on multiple occasions during her ownership. She alleged she was involved in multiple accidents as a result of this condition, and that the condition continued to arise despite multiple repair attempts by authorized dealerships. The jury found at the conclusion of the case that the vehicle was not defective.
- In 2008, Dennis successfully defended an international automobile manufacturer at trial in a matter involving a motor vehicle operator rendered a quadriplegic in an accident. Plaintiff alleged the airbag in his vehicle improperly deployed in the accident, causing him to strike the interior of the vehicle and cause his injuries. While the jury awarded in excess of $20 million to plaintiff against the driver of another vehicle in the accident, it absolved Dennis’ client of liability. The verdict was affirmed on appeal.
