Definition
A Latin maxim meaning "wrongs ought not to remain unpunished" or, more literally, "evil deeds ought not [go without remedy]." The full formulation typically rendered in legal texts is *maleficia non debent remanere impunita* — wrongful acts should not be left without consequence. The maxim expresses a foundational principle of legal order: that the law must provide redress or sanction for harmful conduct, and that courts should not construe rules or procedures in ways that allow wrongs to escape accountability.
As a maxim of construction, it has been invoked to support broad readings of remedial statutes, to resist technical defenses that would defeat a meritorious claim, and to justify the recognition of causes of action where the underlying harm is clear but the precise legal vehicle is contested.

Common Confusion
The source material recovered under this entry conflates several related Latin maxims. Black's 2nd Edition appears to treat this entry alongside or adjacent to *mala in se* (wrongs bad in themselves, as distinguished from *mala prohibita*) and *mala praxis* (malpractice). These are distinct concepts. *Mala in se* is a classification of offenses by their inherent moral character. *Mala praxis* is a specific doctrine addressing professional negligence. *Maleficia non debent* is a maxim of legal policy about the consequences of wrongdoing — not a classification scheme or a cause of action in itself. Researchers should not conflate the three simply because they appear in proximity in older digests and dictionaries.

Why It Matters in Research
This maxim is more commonly encountered in secondary legal literature — treatises, commentaries, and judicial dicta — than in operative statutory or case law. Its primary research value is as an interpretive principle cited to support expansive construction of remedial provisions or to answer arguments that procedural technicalities should defeat a plaintiff's recovery.
In historical corpus research, be aware that this maxim is frequently truncated. You may encounter only the opening words *maleficia non debent* in a footnote or margin gloss, with the remainder of the phrase assumed. Searching for the partial phrase alone will return more results than the full formulation, but those results will require careful contextualization to determine whether the author is invoking the maxim in its remedial sense or using *maleficia* more loosely to describe wrongful conduct generally.
The maxim appears with some frequency in ecclesiastical law commentary and in early common law treatises, where it was used to ground the court's jurisdiction over conduct that might otherwise fall into a procedural gap. In equity jurisprudence, it surfaces as a rhetorical foundation for the principle that equity will not suffer a wrong to be without a remedy — a concept closely related to, and often cited alongside, the maxim *ubi jus ibi remedium*.
Jurisdictional variation in how this maxim is treated is minimal, because it functions as a general principle of jurisprudence rather than a rule of positive law. Its force is persuasive and rhetorical, not binding. Researchers encountering it in judicial opinions should treat it as framing language rather than holding.

Historical Dictionary Support
Black's 2nd Edition does not provide a clean, standalone entry for *maleficia non debent* as a complete maxim. The recovered source material is fragmentary and appears to present the term in the context of a broader alphabetical sweep through Latin *mal-* terms, blending it with entries for *mala in se* and *mala praxis*. This is a notable gap. The maxim was well-established in Roman law commentary — Mackeldey's *Roman Law* (§ 297), cited in the adjacent Black's material, addressed foundational principles of obligation and delict from which this maxim draws — but Black's 2nd does not appear to have treated *maleficia non debent* as a discrete headword with a developed definition.
Earlier common law dictionaries and Blackstone's Commentaries use the underlying concept without always citing the Latin formulation explicitly. Blackstone's treatment of wrongs (*mala in se*, Book 4) and the general principle that the common law abhors a right without a remedy collectively express the same policy the maxim encapsulates.
The fragmentary state of the Black's entry here is itself historically instructive: it reflects the tendency of early American legal dictionaries to include Latin maxims more as reference anchors for practitioners who had encountered them in English sources than as terms requiring independent definition.
