Why Relation Back Matters

Relation Back of Amendments

Why Relation Back Matters

Ernie buys worthless stock from Violet on April 3, 2014, and sues her for breach of contract on April 1, 2017, two days before the three-year limitations period expires. Four months later, further investigation convinces his lawyer that Ernie may also recover from Violet for fraud in the same sale.¹ The contract claim is safely on file. The fraud claim, if it must carry the date of the amendment, is late.

A statute of limitations gives a claim a fixed period, usually measured in years, that runs from accrual until a complaint tolls it.² In the typical auto accident, the claim accrues at the time of the accident, and a plaintiff who files outside the three-year period can be barred by the affirmative defense of limitations.³ Violet can raise that defense against any claim Ernie must date from his amendment. Rule 15(a) might let him add the fraud claim, and limitations would then defeat it. The amendment would accomplish nothing.

Rule 15(c)(1) rescues the claim. An amendment "relates back to the date of the original pleading" when it meets one of the conditions the rule lists,⁴ and one of those conditions is that the amendment arises from the conduct, transaction, or occurrence set forth in the original pleading. The claim is then treated as though it had been asserted in the original pleading.⁵ To relate back is to be backdated. Ernie's fraud claim arises from the sale his contract claim already describes, so it takes the April 1 date and beats the deadline. The result seems fair: when the period ended, Violet was already defending a suit over the stock sale, and the fraud claim adds a second theory about the same sale.

The two versions of Ernie's problem mark the limits of the doctrine. Relation back is a limitations doctrine, and it matters only after the period has run on the new claim or the new party. Before expiration, the amendment must satisfy Rule 15(a) alone. An amended pleading replaces the original, and a party may amend once as a matter of course, without leave of court, if the amendment is filed no more than twenty-one days after the original pleading was served, or after a responsive pleading or a Rule 12(b), (e), or (f) motion was served, whichever is earlier.⁶ Outside that window, amendment is no longer a matter of course. After expiration, satisfying Rule 15(a) is still required but is no longer enough: the amendment must also relate back, or limitations bars it. Every amendment problem therefore starts with one question: has limitations run on the new claim or the new party?

Relation back also sets two interests against each other. A prospective defendant who legitimately believed that the period had passed without any attempt to sue him has a strong interest in repose.⁷ Against that interest stands the conviction on which the drafters built the Civil Rules: pleadings are not of great importance in a lawsuit, as the flexible rules on the form and number of pleadings show.⁸ That conviction points toward letting an amended claim take the date of the original.

In Krupski, the Supreme Court marked where repose stops deserving protection. Repose is a windfall for a prospective defendant who understood, or should have understood, that he escaped suit during the limitations period only because the plaintiff misunderstood a crucial fact about his identity. And because a plaintiff's knowledge that a party exists does not foreclose a mistake about that party's identity, such knowledge does not support the party's interest in repose.⁹ What the defendant knew, and when, therefore carries weight in the cases ahead.

Because those interests pull in different directions, Rule 15(c)(1) lists the conditions under which an amendment relates back instead of announcing one test.¹⁰ The sections that follow take up amendments arising from the same transaction first, then amendments that change the party sued, where the defendant's knowledge matters most.
