Selected Recent Cases

Defective fishing rod injures fisherman

Attorney Diller brought a Product Liability claim against the Chinese manufacturer, designer and the local seller of an unsafe fishing rod which broke under low tension resulting in shrapnel from the rod striking the eye of the fisherman using the rod. Plaintiff’s expert was prepared to testify that the defendants did not test the product to its minimum recommended line strength and the unsafe rod fractured because the composite materials were too weak not to fracture under stress below the recommended line strength. Before trial, at a pre-trial mediation, the case settled.

Teenage motorist injures Motorcyclist

Attorney Diller represented a motorcyclist who suffered a severe wrist injury resulting in multiple surgeries and permanent disability. At trial, Attorney Diller showed that the teenage motorist pulled in front of the motorcyclist and left the motorcyclist no time to react causing plaintiff to be ejected from the motorcycle over the defendant’s car and onto the highway pavement. After five days of trial the case settled.
