The key to any personal injury lawsuit is establishing liability. This area of law is known as product liability, and it requires proving one’s injury resulted from a manufacturing defect, a design defect, or a failure on the part of the manufacturer to adequately warn the user of a known danger or to provide proper operating instructions for the chainsaw. Product liability cases are often quite complex due to the manufacturer having so much on the line. These cases require experienced attorneys with ample resources to investigate case law as well as all the specifics pertaining to your case.
