In Bramford v Turnley, what does "unlawful" mean in the context of private nuisance?

In the context of private nuisance, "unlawful" is understood to refer to conduct that is unreasonable. This concept is rooted in the idea that certain uses of land that interfere with a neighbor's enjoyment of their property are considered nuisances if they are not justified by a legitimate purpose. The standard of reasonableness takes into account factors such as the nature of the harm caused, the social utility of the activity, and the severity of the interference.

In Bramford v Turnley, the court examined whether the actions of the defendant constituted a nuisance by evaluating whether they were reasonable in balancing the interests of the parties involved. If the activity is deemed unreasonable, it may qualify as a private nuisance, making it actionable under tort law.

The other interpretations provided do not align with the legal definition of "unlawful" in this context. While illegal actions could be a subset of what constitutes a nuisance, not all unreasonable conduct is illegal. Furthermore, public disturbances relate more to public nuisance than private nuisance, and actions taken without consent do not necessarily correlate with the standard of unreasonableness required for establishing a private nuisance claim.
