Liquidated damages and mitigation

The Agreed Sum: Forecast or Punishment

A liquidated-damages clause is enforceable when it fixes a reasonable estimate of loss rather than an amount designed to punish breach. Start by identifying the governing regime and the event that activates the clause: a sum payable for late delivery is not necessarily payable for every breach, and a label such as “penalty” or “liquidated damages” does not control.

At common law, apply the traditional two-part test:

1. Difficulty of estimation: When the contract was made, the harm from the relevant breach was difficult to estimate accurately.

2. Reasonable forecast: The stipulated amount was a reasonable forecast of the probable loss caused by that breach.

If either requirement fails, the term is an unenforceable penalty. The injured party then seeks ordinary damages, subject to the ordinary rules of proof and mitigation. The clause does not become enforceable merely because the parties intended it to be binding, and it does not become a penalty merely because the eventual loss is smaller than the agreed sum.

The timing distinction matters. Under the common-law rule reflected in Restatement (Second) of Contracts § 356, reasonableness is principally judged when the parties formed the contract. A court may examine the actual result as evidence, especially when the disparity is extreme, but hindsight does not automatically invalidate a reasonable forecast. Conversely, a clause that imposes the same large sum for a trivial delay and for complete nonperformance is suspect because the amount may be disproportionate to the harm from the minor breach.

The UCC rule is UCC § 2-718(1). A contract for the sale of goods may liquidate damages in an amount reasonable in light of:

• the anticipated or actual harm caused by the breach;
• the difficulties of proving the loss; and
• the inconvenience or nonfeasibility of obtaining an adequate remedy by another method.

An amount that is unreasonably large is void as a penalty. Thus, the UCC expressly allows attention to both anticipated harm and actual harm. Actual loss is relevant, but a smaller actual loss does not automatically defeat the clause; the question remains whether the agreed amount is unreasonably large under the circumstances.

Use this near-miss distinction: a liquidated-damages clause fixes the recovery; a penalty seeks to punish. A clause can validly require a substantial payment even when proving actual harm would be difficult. But calling a punitive sum “liquidated damages” does not convert it into compensation.

A second near miss concerns the amount. A valid clause generally substitutes the agreed sum for proof of actual loss from the covered breach. The claimant ordinarily need not prove actual loss or reduce the agreed sum by showing that a replacement transaction lowered the loss. The claimant also cannot recover both the agreed sum and ordinary damages for the same loss. If the clause is invalid, however, the claimant returns to ordinary damages, and avoidable loss matters again.

For common-law clauses, run this sequence before considering the actual amount of loss:

This is closed-book-you must be able to state the common-law two-part test and UCC § 2-718(1) without prompts.

The Avoidable Loss Rule: A Reasonable Response After Breach

Mitigation asks what the injured party reasonably could have avoided after the breach. It is not a requirement that the party eliminate all loss, predict perfectly, or choose the cheapest imaginable response. The breaching party generally bears the burden of showing both that the injured party failed to act reasonably and the amount that reasonable action would have avoided.

Apply the common-law duty in this order:

1. Identify the post-breach loss. Separate loss caused by the breach from loss that would have occurred anyway.

2. Identify a practical response. Ask what a reasonable person in the injured party’s position would have done after learning of the breach.

3. Test the response for limits. The injured party need not take unreasonable measures or accept undue risk, burden, expense, humiliation, or inferior or fundamentally different performance.

4. Reduce only the avoidable amount. Failure to mitigate is not usually a complete bar. Damages are reduced by the loss that reasonable mitigation would have avoided.

5. Allow reasonable mitigation expenses. A reasonable cost incurred in trying to avoid loss can itself be recoverable, even if the attempt does not succeed.

The duty begins after breach or knowledge of the breach, not before the contract is broken. The question is not whether hindsight reveals a better choice. It is whether the chosen response was reasonable when made, based on the information then available.

Employment illustrates the limit. An employee whose fixed-term employment is wrongfully terminated must make reasonable efforts to find comparable work. If the employee obtains comparable substitute employment, the substitute earnings reduce the recovery. But the employee need not accept any job whatsoever: work that is inferior, fundamentally different, humiliating, or unreasonably distant may be rejected. A lower salary does not automatically make a job unacceptable; if the position is otherwise comparable, refusing it solely because it pays less may create avoidable loss.

The same distinction applies outside employment. A contractor whose customer repudiates a project may reasonably seek another project, but need not accept work requiring a dangerous method or a radically different service. A buyer of defective goods may reasonably obtain replacement goods, but need not purchase an unusable substitute merely to reduce the seller’s liability.

Do not confuse mitigation with causation, certainty, or foreseeability. Those doctrines ask whether and how the loss may be recovered in the first place. Mitigation asks whether a loss that was otherwise recoverable could have been avoided after breach. The sibling chapter on measuring expectation damages handles the categories and measurement of the loss; this chapter supplies the post-breach reduction.

Article 2 uses specialized applications of mitigation for goods. Under UCC § 2-712, a buyer may cover by purchasing substitute goods in good faith and without unreasonable delay. Cover is a reasonable mitigation choice, not an absolute command to buy at any price. If a reasonable substitute is unavailable, or the proposed purchase would be commercially unreasonable, failure to cover does not itself establish avoidable loss.

A seller’s comparable response is resale under UCC § 2-706: the resale must be made in good faith and in a commercially reasonable manner. A seller’s failure to resell does not automatically eliminate all recovery; it means the seller cannot rely on the resale method and must proceed under the applicable alternative measure. The key near miss is this: common-law mitigation asks whether the injured party reasonably reduced loss; UCC cover and resale add statutory good-faith and commercial-reasonableness requirements.

Finally, connect mitigation to liquidated damages. When a valid liquidated-damages term covers the breach, the agreed sum ordinarily controls without a reduction based on actual avoided loss. When the clause is a penalty and therefore unenforceable, ordinary damages apply, including the duty to mitigate. Always decide whether the clause survives before subtracting a hypothetical replacement gain.

One Choice on Screen: A Valid Sum and a Reasonable Substitute

A theater hired a sculptor to create a centerpiece for a gala by June 1. The contract required the sculptor to pay $20,000 if the centerpiece was not delivered on time. When the contract was made, the parties knew that a replacement artist might be unavailable and that the consequences of missing the gala would be difficult to measure; they reasonably estimated the likely loss at $20,000. The sculptor repudiated on May 1, and the theater promptly hired a comparable artist for $5,000 more than the original price. The gala occurred as planned, and the theater seeks the $20,000 stated in the contract.

The Decisive Fact: Three Practice Questions on Clauses and Mitigation

High-Yield Points - ⚡ Biggest Takeaways

Enforce a liquidated sum only when it forecasts compensation rather than punishes breach. Under common law, test difficulty of estimation and reasonable forecast at formation. Mitigation reduces only loss reasonably avoidable after breach, not every loss hindsight identifies.
