Use of sine qua non in law

How is sine qua non used in law?

How do you use the term in a legal context?

Sine qua non is generally used to refer to something that is essential or indispensable

In legal terms, the phrase sine qua non is used in cases where there is a reference to the consequences of an action or a cause and effect scenario.

For example, if a person committed wrongdoing resulting damages, there is a “cause-in-fact” where the wrongdoing resulted in the damages.

The “but-for” test is used to establish that without the wrongdoing, the damage would not have been caused.

In other words, the defendant’s negligent act or omission has lead to the plaintiff’s injuries.

When the “but-for” test is used in lawsuits, typically the court assesses whether the damages suffered by the plaintiff were a sine qua non consequence of the defendant’s negligent act. 

Sine qua non example

Duhaime’s Law Dictionary provides us with a good example of sine qua non in law. 

They cite the case Sumpter v. City of Moulton where the judge stated:

“The test to determine the actual cause prong of causation is known as sine qua non; but for the defendant’s conduct, the harm would not have occurred.”

This is another example of how the term is used in tort related cases where the conduct of the defendant resulted in harm to the plaintiff.

Takeaways 

“Sine qua non” is a Latin phrase you can literally translate to English to mean “without which not”.

Without something, something else is not possible.

Sine qua non refers to an essential condition or something absolutely necessary for something else to happen or occur. 

For example, you need to have funds sine qua non for the purchase of a property.

In law, we often see the term sine qua non used to refer to an essential element or essential condition.
