A remedies concept defining the form, measure, or enforcement of relief available for proven civil claims. It governs monetary awards, equitable orders, or collection mechanisms by specifying prerequisites and limits. It does not provide relief absent a proven claim and does not authorize relief prohibited by governing constraints. It determines practical outcomes by converting legal entitlement into enforceable payment or conduct requirements. The concept is generally stable, though remedial standards and enforcement tools may be updated over time.

Principle

Prejudgment interest restores the injured party to the position they would have occupied had the defendant paid when the obligation matured; rates and availability are governed by statute, contract, or equitable principles.

Demonstration

A seller suffers a breach of contract on March 1 causing a $100,000 loss; the court awards $100,000 plus prejudgment interest from March 1 to the judgment date at the statutory rate to compensate for lost use of funds.

Misapplication

Awarding prejudgment interest on unliquidated speculative damages without a clear accrual date, or duplicating compensation already incorporated into the damages calculation (double recovery).

Consequence

Compensation for delay reduces the benefit of withholding payment, encourages prompt resolution, and aligns damages with economic reality by accounting for time value of money.

Reversal

Post-judgment interest runs from entry of judgment until payment and enforces the judgment's monetary obligation; prejudgment interest operates before judgment and addresses the pre-judgment deprivation period.

Boundary

Applies according to statutory or contractual rules and may be limited for certain claim types (e.g., punitive damages, equitable restitution) or by caps; some claims require liquidated sums or established accrual dates.

Semantic Tension

Tension exists between prejudgment interest and compensatory elements such as lost profits or delay damages — courts must avoid awarding overlapping recovery and choose between interest or incorporated compensatory adjustments.

Synthesis

Prejudgment interest is a compensatory device that awards interest for the period of deprivation between loss accrual and judgment, governed by law and tailored to prevent undercompensation for delayed payment while avoiding double recovery.
