Rylands v Fletcher (1868) - The defendant employed independent contractors to construct a reservoir on their land. The contractors found a disused mineshaft when digging but believed it was filled with earth and failed to seal them properly. They filled the reservoir with water. Unknown to the defendant or the contractors, this mineshaft connected to the claimant's coalmine on neighbouring land, and as a result, water flooded through the mineshafts into the plaintiff's mines on the adjoining property. The defendant had not been negligent, as he had trusted the independent contractors, yet he was liable for the damage to the claimant's land.
