Step 1: Understand defences to nuisance.
- Adverse Possession: This defence applies when the defendant has been in continuous possession of the land for a long time and is generally accepted as a defence in nuisance cases.
- Easementary Rights: The defendant has a right of way or other easementary rights, which are recognised as defences in nuisance actions.
- Good Faith: Good faith can act as a defence in some nuisance cases, especially when the defendant can show that the action was not intended to harm others.
- Voluntary Harm: This is not typically a recognised defence in nuisance cases, as voluntary harm does not excuse the interference.
Step 2: Conclusion.
The correct answer is (A), (B) and (D) only.
