Definition
A Latin maxim of English common law, rendered in full: *Privilegia quæ re vera sunt in præjudicium reipublicæ, magis tamen habent speciosa frontispicia, et boni publici pretextum, quam bonæ et legales concessiones; sed pretextu liciti non debet admitti illicitum.* Translated: "Privileges which are truly in prejudice of the public good have, more than good and lawful grants, a specious appearance and a pretext of public benefit; but under pretext of what is lawful, that which is unlawful ought not to be admitted."
The maxim states a rule of construction and a substantive principle: a grant or privilege that is, in reality, injurious to the common good cannot be saved by the fact that it wears the outward dress of public benefit. Lawful form does not legitimize unlawful substance. Courts applying this principle look past the nominal justification of a privilege or grant to its actual effect on the public interest.

Common Confusion
The abbreviated form "privilegia quæ re vera" is sometimes treated as a self-contained maxim meaning simply "privileges which in truth [are harmful]," as if the principle were about identifying harmful privileges generally. The full maxim is more specific: it addresses the particular danger of privileges that carry a plausible public-benefit justification while actually operating against the public good. The mischief targeted is not obvious bad faith, but disguised prejudice—the specious appearance (*speciosa frontispicia*) being the operative problem. Researchers who work only from an abbreviated citation may underread the maxim's scope.

Why It Matters in Research
This maxim appears in Coke's Reports (11 Co. 88) and is reproduced in Black's 2nd edition in the context of privileged copyhold and ancient demesne tenure—a proximity in the printed text that can mislead a researcher into thinking the maxim is specific to land tenure. It is not. The maxim is a general canon of construction applicable wherever a privilege, grant, or franchise is challenged as contrary to public interest despite carrying a public-benefit pretext.
In the Law Mind corpus, this maxim is most likely to surface in three research contexts: (1) challenges to royal or legislative grants claimed to be in the public interest but alleged to have monopolistic or otherwise injurious effect; (2) construction of corporate charters and franchises, particularly in 19th-century American cases drawing on Coke; and (3) equity arguments that a facially valid grant should not be enforced because its actual operation is contrary to the public welfare.
The key research trap is the fragmentary citation. Black's 2nd edition reproduces only the opening clause before the entry is cut off in the printed source. Researchers relying solely on Black's will have an incomplete text. The authoritative source for the full maxim is Coke's Reports directly. Any research note that cites only Black's for this maxim should be verified against Coke.
A secondary trap: the maxim is sometimes grouped with purely interpretive canons (rules about how to read ambiguous text), but it functions as something stronger—a substantive limit on the enforceability of grants. The distinction matters when assessing how a court is using the maxim: as an aid to construction, or as a ground for voiding a privilege outright.

Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) is the sole historical dictionary source for this entry, and its reproduction of the maxim is incomplete as printed, breaking off after the opening clause. The attribution to 11 Coke 88 is reliable and consistent with the standard citation in English legal literature.
The maxim originates with Coke and reflects a broader Cokean theme: that formal compliance with the procedures for granting privileges does not shield those grants from scrutiny as to their substantive effect on the commonwealth. This principle was influential in English constitutional thought on the limits of prerogative grants and fed into American debates about the scope of legislative power to grant monopolies and franchises. Historical dictionaries prior to Black's do not appear to carry this maxim as a standalone entry; it is transmitted primarily through the reports and commentaries rather than the dictionary tradition.

Jurisdictional Note
The maxim derives from English common law and was most actively applied in English courts construing prerogative grants and franchises. American courts, particularly in the 19th century, cited Cokean maxims in franchise and charter disputes, but the maxim's direct invocation is more characteristic of English legal argument. Researchers working in American state court records should treat citations to this maxim as signals of Coke's influence rather than as evidence of a distinct American doctrine.
