Product liability cases draw upon one or more of these three legal theories of liability. What happened in your particular case will direct the choice of legal argument for your claim. Negligence would be an appropriate charge when someone in the chain of responsibility for the product failed to act with care. Breach of warranty arises when a product fails to meet consumer expectations whether expressly promised by the seller or maker or implied. Strict liability seeks only to collect damages for the party responsible for the defect. It does not require showing an exact failure in any duty only that an unreasonable danger existed.
