Proximate Cause

In order to win a personal injury action, a plaintiff must prove that a defendant's negligence caused the plaintiff's injuries. In negligence law, there are two types of causation: (1) "cause in fact"; and (2) "proximate cause." The plaintiff must prove both types of causation.

The Jones Act -- Unseaworthiness Claims

The owner of a vessel has an absolute duty to provide a seaworthy vessel for his crew. Therefore, an injured seaman may sue the owner of the vessel on which the seaman was working if the vessel was unseaworthy at the time of the accident. A vessel is unseaworthy if it, its equipment, or its crew are not reasonably fit for their intended purpose.

Trespass

Trespass is a physical invasion of a property owner's land. A person may be liable to the owner if he causes a trespass, even if he did not know that it was the owner's land.

Defense of Others

In an action against a defendant for an intentional tort, such as battery, the defendant may defend the action by claiming that he or she acted in self-defense. Similarly, under some circumstances, a defendant may claim defense of others as a defense. Defense of others is a proper defense when the person the defendant was trying to defend would have been justified in using force to defend himself or herself.

Common Law Tort Action Against Person Having Sexual Relations with Female Child

Under the common law, a person who has sexual relations with a female child is liable to the child's parent for damages. The tort action is based on the parent's lack of consent. Damages are based on the parent's loss of services or the medical expenses that the parent incurred on behalf of the child as a result of the sexual relations. Although these types of cases are quite rare and some states have abolished actions for these types of cases, there are still some states in which the cause of action may be maintained.
