Nuisance is a common law tort. It means that which causes offense, annoyance, trouble or injury. A nuisance can be either public (also "common") or private. A public nuisance was defined by English scholar Sir James Fitzjames Stephen as,

"an act not warranted by law, or an omission to discharge a legal duty, which act or omission obstructs or causes inconvenience or damage to the public in the exercise of rights common to all Her Majesty's subjects".

Private nuisance is the interference with the rights of specific people. Nuisance is one of the oldest causes of action known to the common law, with cases framed in nuisance going back almost to the beginning of recorded case law. Nuisance signifies that the "right of quiet enjoyment" is being disrupted to such a degree that a tort is being committed.

Definition

Under the common law, persons in possession of real property (land owners, lease holders etc.) are entitled to the quiet enjoyment of their lands. However this doesn't include visitors or those who aren't considered to have an interest in the land. If a neighbor interferes with that quiet enjoyment, either by creating smells, sounds, pollution or any other hazard that extends past the boundaries of the property, the affected party may make a claim in nuisance.

Legally, the term nuisance is traditionally used in three ways:

1. to describe an activity or condition that is harmful or annoying to others (for example, indecent conduct, a rubbish heap or a smoking chimney).

2. to describe the harm caused by the before-mentioned activity or condition (for example, loud noises or objectionable odors).

3. to describe a legal liability that arises from the combination of the two. However, the "interference" was not the result of a neighbor stealing land or trespassing on the land. Instead, it arose from activities taking place on another person's land that affected the enjoyment of that land.
