Relation Back Under Limitations Law
Rule 15(c)(1)(A) lets an amendment take the date of the original pleading whenever “the law that provides the applicable statute of limitations allows relation back.”1 The subsection hands the question to the body of law that set the deadline, and it asks nothing of the amendment itself: no same-transaction showing under (B), no notice to a new party under (C). Since the rule was amended in 1991, an amendment relates back whenever the limitations law permits it.2 A plaintiff who cannot satisfy (C) can therefore still be timely under a more forgiving limitations law, and a plaintiff who satisfies (B) or (C) never needs (A).
Relation back matters because it can rescue a claim that the limitations period would otherwise bar. In one federal case, a counterclaim first raised in an amended pleading some eight years after the underlying events was assumed to be barred if sued upon separately. The court still thought it could hardly be doubted that the amendment related back to the original filing date under Rule 15(c).3
The doctrine rests on notice. A party who has been told of litigation about a given transaction or occurrence has received all the protection that limitations statutes are designed to afford, so an amendment can relate back even though the limitations period ran in the interim, provided the party learned the general facts at the outset.4 One federal district court calls adequate notice of the occurrence the most important factor. It found the factor satisfied where a complaint alleging negligence in performing an amniocentesis gave the physician notice of an amended claim of lack of informed consent for a sterilization, because both claims concerned his conduct with respect to the amniocentesis.5 A limitations law may build in the same judgment, and (A) lets the federal court honor it.
Applying (A) takes two steps in a fixed order, and the first is to identify the law that provides the limitations period. When a federal court hears a state-law claim, the state's limitations law ordinarily supplies the period. A federal claim can arrive at the same place by borrowing. In Balle v. Nueces County, Texas, a § 1983 suit, the length of the period came from the general personal-injury statute of the forum state, which in Texas allows two years.6
The second step reads that limitations law and asks whether it allows relation back. The question concerns what the limitations law itself provides, so neither fairness nor the other routes in Rule 15(c) can answer it. Silence does not count: a statute that says nothing about amendments allows nothing, and (A) offers no route.7 The plaintiff must then rely on (B) and (C), which the sections that follow take up.
Without (A), those facts would force a choice. Applying only (C), the court would deny the amendment as barred, because the notice requirement is unmet. Applying the state statute, it could allow the amendment, because relation back follows if the more flexible statute governs. Deciding which to apply is a Hanna question.8 Before 1991, the Supreme Court settled a version of that conflict without addressing it. It held that an amendment changing parties related back only if the new party had notice of the suit before the limitations period ran, and that notice within a reasonable additional time for serving process did not suffice. The Court reached that result wholly as a construction of Rule 15(c) and, though the case was a diversity case, did not discuss what a state court might have done.9 The First Circuit's decision in Marshall v. Mulrenin shows the other approach: after the district court held that Rule 15 barred the plaintiff from substituting a different defendant, the court of appeals allowed the substitution under Massachusetts amendment law. The 1991 amendment ended the conflict by adding (A), so that an amendment always relates back if the limitations law permits it.10 Following a more generous state law now overrides nothing, because the federal rule itself tells the court to follow it.
Lindley v. General Electric Co. shows the second step at work through a state device with no federal counterpart. California's Doe practice extends the limitations period for a defendant later named in place of a fictitious one, but federal procedure has no pleading mechanism comparable to California's section 474. The plaintiffs filed a second amended complaint naming Stone & Webster, dropped the Doe defendants as named parties, and stated that the new parties were added in lieu of the Doe designation, which was all federal procedure permitted. The court refused to deny them the three-year extension for failing strictly to comply with section 474's requirement that the new defendant be named and served as a person sued under a fictitious name.11 Ficek v. Kolberg-Pioneer, Inc. applied Montana's fictitious-name statute in the same spirit, letting a named defendant replace a fictitious one and relate back to the original complaint.
The deference runs in one direction only. In Morel v. DaimlerChrysler AG, the plaintiffs sued within Puerto Rico's one-year period but did not name the defendant until after it ran, and the defendant argued that Puerto Rico's stricter rule should govern. The First Circuit held that the federal relation-back routes still applied and tested the amendment under (C). Subsection (A) thus works as a one-way ratchet: a more generous limitations law adds a route, and a stricter one subtracts none. The text explains why. Subsection (A) asks only whether the limitations law allows relation back, so a yes supplies a route and a no supplies nothing, while (B) and (C) rest on the federal rule alone.12
A common mistake is to reason that, because state law supplies the limitations period in a diversity case, state relation-back law supplies the whole answer. State law can add a route under (A), but a stricter state rule leaves the federal routes standing, so the amendment must still be tested under (B) and (C).
