Understanding the Rule of the Floating Subtrahend in Tort Law

Definition & Meaning

The rule of the floating subtrahend is a legal principle in tort law. It requires a plaintiff, who has suffered damages, to demonstrate the specific amount of those damages that are not caused by the defendant. If the plaintiff cannot prove this amount, they may not be able to recover any damages at all. Essentially, this rule emphasizes the need for clear evidence of loss that is directly attributable to the defendant's actions.
