  • 9/15/2017 · Product Liability
    In the United States, the most litigious country in the world, a products liability action may be brought, under state law, for express or implied breach of warranty, misrepresentation and negligence. Under the theory of strict liability, a lawsuit may be initiated on the grounds of manufacturing and design defects as well as poor and inadequate warning instructions. The best defensive strategy for a company to avoid becoming involved in any of the above is to manufacture the safest product possible within parameters of economic feasibility. If said manufacturer can vouch for safety factors in the design, production, testing, inspection and evaluation of its product as well as attentiveness to consumer complaints, it will be more likely to avoid litigation or at least be able to prevail in the courtroom.
