What is the definition provided in Rylands v Fletcher related to bringing something onto land?

The definition provided in the case of Rylands v Fletcher emphasizes the principle that liability is established when a person brings onto their land something that is considered dangerous if it escapes. This landmark case articulates the idea that an individual can be held responsible for the consequential harm caused by the escape of a hazardous substance or item. The rationale behind this rule is rooted in the notion of strict liability; if a person introduces potentially harmful elements onto their property, they are responsible for the damage that may result from those elements if they were to escape.

This aligns with the foundation of the nuisance law, where the focus is on the risk posed by the items rather than their inherent characteristics. In Rylands v Fletcher, the context was related to the storage of water, which, while harmless in contained form, became dangerous once it escaped. This principle applies to various scenarios and highlights a clear understanding of liability in tort law concerning dangerous items and their potential to cause harm upon release.
