Philadelphia Court Grants Forklift Manufacturer’s Motion for Summary Judgment

» Read Story

Appellate victory in Pennsylvania Superior Court affirming the Trial Court decision to grant Preliminary Objections under the doctrine of lis pendens dismissing a second Complaint filed in a more favorable jurisdiction when first Complaint was still pending in another jurisdiction.

Summary judgment granted to a building products supplier in a toxic tort action in Philadelphia. Plaintiff presented evidence suggesting the building products may have contained asbestos, but we asserted there was insufficient evidence the building products contained asbestos and argued it was likely the decedent’s exposures to asbestos were associated with his career as a pipefitter.

Summary judgment granted to an electrical product manufacturer defendant in a toxic tort case in Philadelphia County. During Plaintiff’s deposition, the defendant was directly identified among several defendants that allegedly manufactured asbestos-containing products the plaintiff worked with during his career as an electrician. We successfully argued that any exposure the plaintiff may have had to asbestos released from defendant’s product was minimal and failed to satisfy the Pennsylvania standard for causation.

Summary judgment granted in Philadelphia asbestos claims on behalf of a truck brake manufacturer. The Plaintiff, a mechanic, testified he was exposed to asbestos from work involving brakes manufactured by several defendants including brakes manufactured by our client. We established the plaintiff was unable to recall virtually anything about our client’s product or the alleged exposure, including the shape or design of the brake or the length, duration, or frequency of his alleged exposure.  In addition, we also established the plaintiff was aware of the hazards of asbestos before he ever encountered our client’s brake product, that he suspected the brake may have contained asbestos before working with it, and that he took precautions when working with the brake to minimize his exposure.
