=====Negligence=====
A basic [[negligence]] claim consists of proof of

# a duty owed,
# a breach of that duty,
# the breach was the cause in fact of the plaintiff's injury (actual cause)
# the breach proximately caused the plaintiff's injury.
# and the plaintiff suffered actual quantifiable injury (damages).

As demonstrated in cases such as ''[[Winterbottom v. Wright]]'', the scope of the duty of care was limited to those with whom one was in privity. Later cases like ''[[MacPherson v. Buick Motor Co.]]'' broadened the duty of care to all who could be foreseeably injured by one's conduct.

Over time, negligence concepts have arisen to deal with certain specific situations, including [[negligence per se|negligence ''per se'']] (using a manufacturer's violation of a law or regulation, in place of proof of a duty and a breach) and [[res ipsa loquitur]] (an inference of negligence under certain conditions).
