What Is the Duty to Mitigate?
A breach doesn’t give the non-breaching party a blank check to let losses pile up. California law — like the Restatement and the UCC — requires the injured party to take reasonable steps to limit the damage before collecting from the party who broke the deal.
The duty to mitigate (also called the doctrine of avoidable consequences) bars recovery for losses the non-breaching party could have reasonably avoided. It doesn’t demand heroics or financial risk-taking — only ordinary, reasonable effort. On the California Bar Exam, this doctrine shows up constantly in employment essays and UCC goods essays, and the reasonableness standard is where most students lose points.
Who Has the Burden of Proof?
The breaching party must plead and prove that the non-breaching party failed to mitigate. That burden allocation matters: if the facts are silent on whether the injured party looked for substitute work or tried to cover, assume mitigation was reasonable unless the facts affirmatively show otherwise.
Common Law Mitigation: The Employment Context
Wrongful-termination fact patterns are the classic mitigation battleground. A wrongfully discharged employee must seek substantially similar employment — comparable pay, rank, and location — to mitigate lost wages. The employee is not required to accept:
- A job of lower rank or status,
- A position requiring relocation,
- Work in a different field or profession, or
- A job with materially lower pay (even a 20% cut is often too much).
This standard traces to Parker v. Twentieth Century-Fox Film Corp. (1970), where a Hollywood actress declined a different, less prestigious film role after her original contract was breached; the court held she had no duty to accept a substantially different or inferior part to mitigate.
Mitigation Under UCC Article 2 (California Commercial Code)
Once you leave services and enter a goods contract, the mitigation duty is codified as the cover and resale obligations under California’s Commercial Code Division 2:
- Buyer’s duty to cover (Cal. Com. Code § 2712): if the seller breaches, the buyer should make a reasonable effort to purchase substitute goods. Failing to cover when cover was reasonably available limits the buyer to market-price damages under § 2713 rather than actual cover costs.
- Seller’s duty to resell (Cal. Com. Code § 2706): if the buyer breaches, the seller should make a reasonable effort to resell the goods. Failing to resell caps the seller’s recovery at the market-price differential.
Notice the parallel structure: common law calls it “mitigation,” the UCC calls it “cover” or “resale,” but the underlying reasonableness inquiry is identical.
What Mitigation Does NOT Reduce
This is the single most tested nuance in mitigation essays. The duty to mitigate limits consequential damages only — indirect losses like lost profits from a delay. It does not reduce:
- The core loss-in-value figure — the contract-versus-market or cover-versus-contract differential remains fully recoverable regardless of mitigation.
- Incidental damages — direct, reasonable costs of dealing with the breach (shipping, storage, phone calls to arrange cover) are recoverable even without a showing of mitigation.
- The costs of the mitigation attempt itself — if a wrongfully fired employee travels to interview for a substitute job, those travel costs are recoverable even if the interview doesn’t pan out.
A Comparison Table for Exam Answers
| Concept | Governs | What It Reduces | Key Authority |
|---|---|---|---|
| Employee mitigation | Common law | Lost wages beyond what a comparable job would have paid | Parker v. Twentieth Century-Fox |
| Buyer’s cover duty | UCC / Cal. Com. Code | Consequential damages above the market differential | Cal. Com. Code § 2712 |
| Seller’s resale duty | UCC / Cal. Com. Code | Consequential damages above the market differential | Cal. Com. Code § 2706 |
| Incidental damages | Both tracks | Not reduced by mitigation | Cal. Civ. Code § 3300 |
Worked Hypothetical
Facts: Publisher contracts with Author to print 10,000 books for $50,000, delivery by October 1. Publisher breaches and refuses to print. On October 5, Author hires another printer for $65,000, with delivery by November 1. Author also claims $20,000 in lost launch-event profits caused by the one-month delay.
Analysis: Author’s core expectation damage is the cover price minus the contract price: $65,000 − $50,000 = $15,000. That figure is unaffected by mitigation. The $20,000 in lost profits is a consequential loss, so it is subject to the duty to mitigate — if Author could have found a faster (even pricier) printer and didn’t try, the lost-profits claim shrinks. If no faster printer was reasonably available, Author recovers the full $20,000, assuming the delay-related loss was foreseeable at contracting. Any incidental costs Author incurred lining up the replacement printer (calls, travel) are recoverable outright.
Frequently Asked Questions
Does failing to mitigate bar recovery entirely?
No. Mitigation only reduces the avoidable portion of consequential damages. The non-breaching party still recovers the core loss-in-value and incidental damages regardless of any mitigation failure.
Must a wrongfully terminated California employee accept any job offer?
No. The offered job must be substantially similar in pay, rank, and location. An employee can decline a demotion, a pay cut, or a relocation without losing the right to full remaining-wage damages.
Is a buyer required to cover under California’s Commercial Code?
Not strictly required, but a buyer who fails to cover when reasonable cover was available loses the ability to claim actual cover costs and is instead limited to the market-price measure under Cal. Com. Code § 2713.
Key Takeaways
- The duty to mitigate requires reasonable, not extraordinary, efforts to limit loss.
- The breaching party bears the burden of proving a mitigation failure.
- In employment cases, the employee need only accept substantially similar work.
- In goods cases, California Commercial Code §§ 2706 and 2712 codify the seller’s resale duty and buyer’s cover duty.
- Mitigation limits consequential damages only — never the core loss-in-value or incidental damages.
