Definition
Proscribed means formally prohibited, condemned, or outlawed by legal authority. In modern legal usage, something is proscribed when a statute, regulation, court order, or other authoritative instrument expressly forbids it. Proscribed conduct is conduct placed beyond the bounds of legality by an explicit legal command.
In the older civil law tradition, the term carried a sharper and more severe meaning: a person was proscribed when the state had condemned them — either by placing a price on their head or, more commonly, by subjecting them to a punishment that stripped them of civil status entirely. Proscription in this sense was the legal mechanism of civil death.

Common Language
Modern common usage (Wiktionary): Simple past and past participle of proscribe — that is, to have formally prohibited or banned something.
Historical common usage (Webster's 1913): To put outside the protection of the law; to outlaw; to exile; to denounce as dangerous.
The gap between common and legal meaning is modest but worth noting. In ordinary modern English, proscribed functions as a near-synonym for "forbidden" or "banned," and that usage aligns reasonably well with contemporary legal meaning. The divergence is historical: in Roman and civil law sources, proscription was not merely prohibition but a specific formal act of state condemnation that severed the individual from all civil rights and protections. A researcher encountering proscribed in a historical legal text cannot assume the modern "merely prohibited" sense — the term may signal something far more drastic.

Common Confusion
PROSCRIBED vs. PRESCRIBED: These two words are phonetically close and appear in similar legal contexts, but they are antonyms in effect. Prescribed means formally directed or required; proscribed means formally forbidden or condemned. Regulatory and criminal law texts use both. Confusing them inverts the legal command entirely.
PROSCRIBED vs. PROHIBITED: In contemporary legal drafting, proscribed and prohibited are often used interchangeably. Proscribed carries a somewhat more formal or absolute register and, in historical sources, carries additional weight tied to civil law condemnation. Prohibited is the more common term in modern statutes and regulations.

Why It Matters in Research
Researchers working in the Law Mind corpus should approach proscribed with sensitivity to context and era.
In modern materials — constitutional law, administrative law, criminal statutes — proscribed is a drafting term meaning expressly forbidden. Courts and legislatures use it to identify conduct placed outside legal permission. First Amendment doctrine, for instance, frequently distinguishes between proscribed speech (categories the government may lawfully forbid, such as true threats or incitement) and protected speech. In this context, proscribed has constitutional load: not everything offensive or harmful is legally proscribable.
In historical legal materials, particularly civil law sources and treatises drawing on Roman law, proscribed carries the heavier meaning described above — condemnation to civil death, outlawry, or the forfeiture of the protection of law. A person who was proscribed in this sense was not merely subject to a penalty; they were cast outside the legal order. Cod. 9, 49, cited in both editions of Black's, is the Justinianic source anchoring this usage. Researchers consulting nineteenth-century treatises, equity materials, or civil law scholarship should be alert to this older register.
The dual valence of the term creates a layered research challenge: the same word means something procedurally and normatively different depending on whether the source is a modern federal statute or a historical civil law commentary. Collapsing the two meanings will produce misreadings.

Historical Dictionary Support
Both editions of Black's Law Dictionary are in complete agreement and present identical text, which suggests the entry was carried forward without revision. Both locate the term firmly in the Roman civil law tradition, distinguish the two senses (price on one's head; civil death), and cite Cod. 9, 49 as the primary source.
What neither edition addresses is the term's migration into modern Anglo-American legal usage, where proscribed has shed its civil law connotations and operates simply as a synonym for prohibited or forbidden. The historical entries are useful for understanding sources written in the civilian tradition but offer no guidance on the modern constitutional or statutory context in which proscribed most frequently appears today. A researcher relying solely on Black's historical entry would have an incomplete picture of how the term functions in contemporary legal texts.
