The plaintiff in a product liability lawsuit has suffered $100,000 worth of damages from an automobile accident. A defect in manufacture of the plaintiff's vehicle is found to be 60 percent responsible for the accident, while the plaintiff's own negligence is 40 percent responsible. Under the doctrine of comparative negligence, how much would the defendant -the manufacturer of the vehicle - have to pay the plaintiff in damages?


Explanation: The doctrine of comparative negligence states that the defendant would be liable for a total of 60,000 or 60% of the total damages. The doctrine requires that damages in a civil suit be divided based on the parties relative degree of negligence.

Harry sees a semi-automatic rifle that he likes in a gun shops window. The price asked for it is $2,500. Harry signs a written contract promising to pay the $2,500 on Friday, taking possession of the rifle when payment is made. On Thursday, a law becomes effective making the ownership, sale, or possession of such a semi-automatic rifle illegal. The contract between Harry and the shop

automatically terminates due to impossibility.

Explanation: A law making the ownership of firearms illegal would bring up the doctrine of impossibility. In contrast to impracticality, impossibility occurs when the terms of the document cannot be completed - in this case due to a newly passed law. Bottom line, the contract between Harry and the Gun Store would terminate automatically.

These mud flaps have been proven to make driving in the rain significantly safer due to reduced mist created by trucks driving in the rain, although data regarding accidents and injuries has not yet been determined. Any truck entering Kansas must have these flaps installed or will be subject to a significant fine and delay. The cost for purchase and installation of these flaps is $1,000 per truck. In short, trucks must have these flaps or go around the state. This Kansas law 

is invalid because although on its face it's an intrastate law, this statute will have a significant economic effect on interstate commerce causing an undue burden
