Exxon Mobil Corp. v. Allapattah Services, Inc.

2005-06-23

Headline: Federal court access expanded: Court allows related class members and joined plaintiffs with smaller claims into federal court when at least one plaintiff meets the diversity dollar threshold, affecting class actions and joined-plaintiff suits nationwide.

Holding: When a civil action includes at least one named plaintiff who meets §1332’s amount-in-controversy requirement, 28 U.S.C. §1367 permits federal courts to exercise supplemental jurisdiction over other related plaintiffs’ claims that fall below that amount.

Real World Impact:

Allows class members with small claims into federal court when a named plaintiff meets jurisdictional amount.
Permissively joined plaintiffs can keep related claims in federal court below $75,000.
Makes it easier to resolve multiple related claims together in one federal lawsuit.

Summary

Background

Two consolidated cases asked whether federal courts may hear related claims brought by additional plaintiffs who do not meet the statutory dollar minimum for diversity cases if at least one named plaintiff does. In one case about Exxon dealers, a jury verdict led a court to extend federal jurisdiction to class members whose individual claims were under the amount required. In the other, a child and her family sued over an injury; the appeals court held the family’s claims could not stay in federal court because they did not meet the dollar threshold.

Reasoning

The majority read 28 U.S.C. §1367 as a broad authorization: if a court has original jurisdiction over at least one claim in a civil action, it may exercise supplemental jurisdiction over related claims that arise from the same case or controversy, including claims involving joined or intervening parties. The Court rejected ideas that all claims must independently meet the jurisdictional test or that a low-value claim “contaminates” the whole action. It concluded §1367, by its plain text, authorizes supplemental jurisdiction over the additional plaintiffs at issue and overruled earlier cases that had required every plaintiff to show the jurisdictional amount.

Real world impact

The ruling makes it more likely that class members and permissively joined plaintiffs with smaller claims can have those claims heard in federal court alongside larger claims. The decision resolves a split among appeals courts and will shape how many multi-plaintiff and class suits are handled, though it does not decide the underlying merits of any plaintiff’s claim.

Dissents or concurrances

Two Justices dissented, and one wrote separately, arguing the statute is ambiguous and that legislative history and precedent counsel preserving the older rule (which required each plaintiff to meet the dollar amount). They would have left Clark and Zahn in place and reached the opposite result in at least one case.
