It's Not My Fault!

Rylands v. Fletcher (1868)

Today’s #casefiles entry takes us to Victorian England and a story that started with water, ended with a mine collapse, and changed the way the law thinks about responsibility. This is Rylands v Fletcher (1868), more popularly known as the case that birthed the principle of strict liability.

What happened?

Thomas Fletcher was a mill owner in Lancashire in the mid-1800s. He wanted to improve his business and decided to build a reservoir on his land to supply water to his mill. He hired independent contractors to handle the construction, and all seemed fine at first.

But there was a problem no one spotted. Underneath Thomas’ land, old, unused mine shafts connected directly to an active coal mine owned by his neighbor, Joseph Rylands. The contractors didn’t properly seal the shafts, as they should have, and when Thomas’ reservoir was filled with water, disaster struck.

Water burst through the old shafts and flooded Joseph's working mine. Years of work, equipment, and profits were destroyed in a matter of hours.

Needless to say, Joseph did not like this at all.

He was furious. He hadn’t done anything wrong, yet his entire mine was ruined. Thomas, while sorry about what happened to Joseph, argued that he hadn’t been negligent. He’d hired competent contractors and couldn’t have predicted the disaster. Surely the blame had to go to them for not noticing, right?

So, who was responsible for the damage?

What did the courts say?

The case went to the Court of Exchequer, where the judges initially sided with Thomas, saying he wasn’t negligent. But Joseph appealed, and the case eventually reached the House of Lords (now known as the UK Supreme Court).

The House of Lords laid down a rule that is still quoted more than 150 years later:

“The person who, for his own purposes, brings onto his land and collects and keeps there anything likely to do mischief if it escapes must keep it at his peril. If he does not, he is prima facie answerable for all the damage, which is the natural consequence of its escape.”

In plain terms: Thomas had to pay for the destruction of Joseph’s mine. The fact that he didn’t personally cause the leak or that he’d taken reasonable steps didn’t matter.

The court believed that when you bring something potentially harmful onto your land, which in this case was large amounts of water in a reservoir, and it escapes, you bear the cost. It was better for the person who created the risk to absorb the loss than for an innocent neighbor to suffer.

This was the birth of the principle of strict liability: you are responsible for the damage caused by dangerous things you bring onto your property, even if you weren’t negligent.

Could Thomas have argued fairness?

Many people might feel for Thomas. He didn’t intentionally harm Joseph, and he’d reasonably trusted professionals to build the reservoir properly. But the House of Lords wasn’t moved by that argument.

The judges felt that if someone like Thomas chose to introduce risk, he must also accept the consequences if things go wrong. He could have insured himself or ensured the reservoir was built with more caution.

Why should you care?

The rule from Rylands v. Fletcher still shapes the law today, and now, its impact goes far beyond reservoirs. It’s the reason businesses, landlords, developers, and even regular people must think carefully about the risks they create.

Think about it:

If a filling station near your home stores thousands of liters of petrol underground and there’s a leak that allows said petrol to seep into your water supply, the owners can’t shrug and say, “We didn’t mean to.” They’ll be held responsible, because they stored the petrol in there.

Or let’s say your landlord keeps a pack of vicious pit bulls in a poorly fenced compound and one escapes and attacks your sister. The landlord can’t argue the dog “doesn’t usually act like this” or that he wasn’t negligent.

When fuel tankers tip over and explode on Otedola Bridge or any other highway nationwide and cause damage to people and property, the same applies to the parent companies as well.

The logic is simple: if you create a potential danger, you must bear the consequences if it harms others, even if you didn’t see it coming.

For business owners, it’s a sharp reminder that insurance and preventive measures aren’t luxuries; they’re essential. You can’t rely on merely having good intentions or competent contractors to shield you from liability.

For everyday people, the principle is protective. It means that if your neighbor’s dangerous activity damages your home, business, or health, the law is on your side. You don’t have to prove they were careless, only that the danger they created escaped and caused harm.

The lesson? The risks you bring into the world aren’t just yours. If they spill over and hurt someone else, the law will hold you accountable.

I’ll end this entry with the same lesson I pointed out in a previous edition of #casefiles about Donoghue and Stevenson: always have in mind that you are accountable to your neighbor and will be held accountable by the law should any harm be caused.
