Bruce Wayne is the head librarian at the Gotham City Library. Bruce hires Peter Parker, a private security guard, to monitor the library at night. Peter’s job is to walk through the library at closing time to make sure no patrons are still in the building and then lock the doors for the night. One night, Peter locks up like he is supposed to but he forgets to walk through the building first. Unfortunately, Clark Kent, an avid reader, is in the library and does not realize that the library has closed. Because Peter forgot to walk through the building, he does not realize that Clark is still inside and Clark gets locked inside the library for the night. If Clark sues Peter for False Imprisonment, Clark will lose because Peter did not intentionally lock Clark in the library. However, even though Clark will not recover for an intentional tort, he can still sue and possibly recover against Peter for negligently locking him in the library.
The four elements that a plaintiff must prove to win a negligence suit are 1) Duty, 2) Breach, 3) Cause, and 4) Harm. When trying to establish a case for negligence, you must make sure that all four elements have been met:
The first step in analyzing a negligence scenario is to establish whether or not the defendant owed the plaintiff a duty. There are two kinds of duty that a defendant could owe the plaintiff. The first is the general “duty of care”. The duty of care is simply a duty to conduct yourself as a reasonable person, acting under similar circumstances, would conduct himself. In any negligence suit we look at the defendant’s actions and try to determine whether a reasonable person would have acted the way the defendant acted had the reasonable person been in the same circumstances that the defendant was in. If the defendant’s behavior matches the reasonable man’s behavior the defendant has fulfilled his duty of care. If the defendant’s actions fall below what a court determines the reasonable man’s actions would have been the defendant has breached his duty.
The second duty is a “special duty” imposed by statute or case law which may exist either in addition to, or in place of the regular duty of care. For example:
A state passes a law requiring all home owners to shovel snow from the sidewalks in front of their houses. Thanks to this law, every home owner in the state has a special duty to all pedestrians to make sure that his sidewalks are clear of snow.
In order to determine duty you must look at the relationship between the plaintiff and the defendant and identify whether or not, based on that relationship, the defendant owed duty to the plaintiff.
Once you have determined the existence of a duty, you must determine whether or not the defendant has breached his duty. A defendant can breach his duty both by acting in a certain manner or by failing to act in a certain manner. That is to say, a defendant can breach his duty either by acting in a manner that violates the reasonable man test, or by not acting in a situation where he is legally required to act.
Once you have demonstrated that the defendant owed a duty to the plaintiff and that the defendant breached that duty, you must show that the breach was both the actual and proximate cause of the plaintiff’s harm.
Finally, you must show that the plaintiff suffered harm as a result of the defendant’s breach. If a plaintiff does not suffer harm, he can not sue for negligence. For example:
Hermann is an avid skier. One day, while practicing his slaloming technique, he suffers a bad fall and breaks his right leg. At the hospital, the doctor accidentally casts Hermann’s left leg. The left leg remains in a cast for two months while the broken right leg goes untreated. Somehow, the broken right leg heals by itself and Hermann suffers no harm because of the doctor’s mistake. Because Hermann has not suffered any harm, he will not be able to sue the doctor for negligence.
Please note that, as with intentional torts, there are several possible defenses to a charge of negligence. As the final step in your analysis you must go through these possible defenses to see if the defendant can use one of them to insulate himself from liability.
