In order the better to secure to the owner and occupier of land its proper use and enjoyment the common law has recognized certain rights in addition to the mere right of possession which is redressed by the action of trespass. These non-possessory rights are called natural rights because, like the right of possession, they exist irrespective of the consent of others. Any violation of these natural rights is called a private nuisance.
