Whether EPCRA's authorization of a citizen suit for particular reporting failures is a subject-matter-jurisdiction requirement that must be decided before Article III standing.
Holding
No. Whether EPCRA creates a cause of action for wholly past violations is a merits question, not a limit on the federal courts' subject-matter jurisdiction.
Reasoning
A federal court does not lose subject-matter jurisdiction merely because a plaintiff may ultimately fail to state a valid federal claim. Under Bell v. Hood, jurisdiction exists when the complaint presents a nonfrivolous federal claim whose success turns on the proper construction of federal law. Here, the parties genuinely disputed whether EPCRA covers late filings that were completed before suit, so the claim was neither immaterial nor frivolous.
EPCRA's provision that district courts have jurisdiction in actions brought under the citizen-suit subsection was read as identifying the court's remedial authority, not as converting every element of an EPCRA claim into a jurisdictional prerequisite. Treating each disputed statutory element as jurisdictional would require courts to raise and resolve ordinary merits disputes on their own initiative and would improperly expand the category of jurisdictional defects.
The Court distinguished Gwaltney of Smithfield, Ltd. v. Chesapeake Bay Foundation, which had described a similar Clean Water Act issue in jurisdictional terms. That characterization did not control because Gwaltney did not examine the distinction between a cause of action and subject-matter jurisdiction, and its resolution of that label made no practical difference in that case.
