Definition
Popular actions are civil suits brought to recover a penalty created by a penal statute, where the right to sue is open to any member of the public rather than reserved to a specific injured party or government official. The name derives from the Latin concept of an action belonging to the people (populus): because no single person holds an exclusive right to prosecute, any willing private citizen may step forward as plaintiff. The recovery sought is typically a statutory penalty — a fixed sum prescribed by the legislature — rather than compensation for a personal injury. Where a statute divided the penalty between the private prosecutor and the Crown or public treasury, such actions were also called penal actions or qui tam actions, the latter phrase (from the Latin qui tam pro domino rege quam pro se ipso — "who sues as much for the king as for himself") identifying suits where the relator shared in the recovery.
Common Confusion
Popular actions, penal actions, and qui tam actions are closely related but not identical. A popular action is the broader category: any suit on a penal statute open to the general public. A qui tam action is a specific subset in which the plaintiff sues on behalf of both the government and himself and receives a portion of the penalty as informer's reward. A penal action is sometimes used as a synonym for popular action, sometimes more narrowly to mean any suit to enforce a statutory penalty regardless of who may bring it. In historical sources these terms overlap heavily, and a researcher should not assume that a source using one term excludes the others.
Why It Matters in Research
Popular actions appear frequently in English common law sources from the seventeenth through nineteenth centuries and are essential background for understanding the American qui tam mechanism that survives today in the False Claims Act. Researchers working in pre-twentieth-century materials should be alert to several traps.
First, the category was largely abolished or absorbed by statute in England over the course of the nineteenth century, so post-reform English sources treat it as a historical relic while American courts, particularly federal courts interpreting the original 1863 False Claims Act and its successors, continued to apply the underlying logic. The two lines of authority diverge sharply after roughly 1870.
Second, the standing question that animated popular actions — who has the right to sue when no personal injury exists — directly anticipates modern debates about informational standing, citizen-suit provisions in environmental statutes, and relator standing under the False Claims Act. Primary sources on popular actions are therefore useful context for researching those modern doctrines even when the term itself does not appear.
Third, historical digests often index these suits under "penal actions," "qui tam," or "informers" rather than "popular actions." A search limited to the phrase popular actions will miss substantial related material.
Fourth, the corpus connection to toll-related entries is not accidental: Rapalje & Lawrence's entry cross-references pecuniary exactions on vessels (port tolls), reflecting the fact that many early popular actions arose from commercial regulatory statutes — navigation acts, port duties, trading regulations — where enforcement by private informers supplemented weak public enforcement capacity. Researchers tracing the history of regulatory enforcement will find popular actions a key mechanism bridging private litigation and public law.
Historical Dictionary Support
Rapalje & Lawrence provide the core formulation: popular actions are those maintainable by any person for recovery of a penalty under a penal statute, and they bear the name "popular" precisely because the right to prosecute belongs to the people at large rather than to any designated individual. This is a reliable and adequate working definition for most research purposes.
The Rapalje & Lawrence entry is notable, however, for an editorial juxtaposition that appears to be a typesetting artifact rather than a substantive connection: the definition of popular actions runs directly into a definition of port tolls (pecuniary exactions on vessels). These are separate entries sharing a column; the tolls material is not part of the definition of popular actions. Researchers using the original text should not read the two as connected doctrine.
What the historical dictionaries collectively do not address is the constitutional dimension that became critical in American law: whether Congress may confer standing on private relators to enforce public rights, and whether such conferral satisfies Article III injury-in-fact requirements. That question, which the Supreme Court addressed in Vermont Agency of Natural Resources v. United States ex rel. Stevens (2000), has no meaningful counterpart in the English sources from which Rapalje & Lawrence drew.
Jurisdictional Note
Popular actions as a distinct common law category are a feature of English and early American law and are no longer recognized under that name in most jurisdictions. Their functional descendant in United States federal law is the qui tam provision of the False Claims Act (31 U.S.C. §§ 3729–3733). Several states maintain analogous state false claims statutes with qui tam provisions. English law largely displaced the mechanism through the Common Informers Act 1951 and predecessor reforms.
