sine qua non

Definition

An essential condition or element, literally 'without which, not.' In causation analysis, it's the 'but for' test—but for this action, would the harm have occurred?

Example Usage

The prosecutor argued that the defendant's actions were the sine qua non of the victim's injuries.

Origin

Latin 'sine qua non,' meaning 'without which not'

Fun Fact

Sine qua non sounds fancy but it's just asking 'would this have happened anyway?' with a classical education.

plead

To formally state your position in court, whether you're begging for mercy, proclaiming innocence, or making legal arguments that will bore everyone except the lawyers. In criminal cases, it's how you answer the charges (guilty, not guilty, or the spicy option: no contest). Can also mean earnestly begging for something, though that's usually less effective in court than in movies.

mitigate

The legal version of damage control—reducing the severity of harm, losses, or consequences rather than eliminating them entirely. In litigation, you have a duty to mitigate damages, meaning you can't just sit back and let things get worse then blame the other party. It's the court's way of saying "at least try to help yourself."

arbitrament

The fancy legal word for what happens when an arbiter makes their final ruling, because apparently "arbitration decision" wasn't Latin enough. Think of it as the judge's mic drop moment, except in binding written form. Still used by lawyers who bill by the syllable.
