Definition
In its specialized legal-historical sense, an outage was a tax or charge imposed by the state of Maryland on hogsheads of tobacco destined for export, collected in connection with official inspection and marking of the goods. The charge was levied as part of Maryland's tobacco inspection regime and was challenged on constitutional grounds as a regulation of interstate and foreign commerce.
Common Language
Modern common usage (Wiktionary): A temporary suspension of operation, especially of electrical power supply; also, the amount of something lost in storage or transportation.
Historical common usage (Webster's 1913): Not separately listed as a distinct entry in Webster's 1913 in this corpus.
The gap between common and legal meaning here is significant and directional: virtually all modern readers will interpret outage as referring to power or service interruptions — a meaning that did not exist in legal or common usage when the Maryland tobacco charge was active. A researcher who encounters outage in a nineteenth-century legal document should not import the modern infrastructure-failure meaning. Conversely, a researcher working in modern utility regulation, energy law, or insurance will find the legal dictionary entry unhelpful and should treat the term according to its contemporary ordinary meaning.
Why It Matters in Research
The legal meaning of outage is narrow, historically bounded, and jurisdiction-specific. Researchers encountering this term in general legal sources, modern practice materials, or secondary literature will almost certainly find it used in its ordinary English sense — power failures, service interruptions, or commodity loss in transit — none of which carry the specialized legal freight of the Maryland tobacco tax usage.
The constitutional significance of the term lies entirely in Turner v. Maryland, 107 U.S. 38 (1883), where the Supreme Court struck down Maryland's outage charge as an unconstitutional burden on interstate commerce. That case is the controlling authority giving the term its legal meaning, and it is the primary reason the term appears in Black's at all. Without that litigation history, outage would not merit a legal dictionary entry distinct from its ordinary usage.
Researchers working in nineteenth-century commerce clause materials, state inspection fee jurisprudence, or the history of tobacco regulation will find outage relevant. For all other research contexts, the term almost certainly carries its common meaning and should be treated accordingly.
Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) defines outage solely by reference to the Maryland tobacco inspection charge, pointing readers directly to Turner v. Maryland and Turner v. State, 55 Md. 264. The entry is entirely descriptive and historically anchored — it does not generalize the term to any broader legal principle.
No other shelf legal dictionaries in the Law Mind corpus carry a distinct entry for outage. The absence of the term from later editions of Black's and from competing dictionaries confirms that its legal meaning was effectively exhausted by the Maryland tobacco inspection context. Once that regulatory regime was struck down and the underlying practice ceased, the term reverted entirely to its common English senses.
What historical sources miss: the commodity-loss meaning of outage — referring to measurable reduction in quantity of goods during storage or transport — does appear in trade and commercial usage of the nineteenth century, and occasionally surfaces in insurance, shipping, and warehousing disputes. This secondary commercial meaning is not captured in the legal dictionaries but may be relevant to researchers working in those areas.
Jurisdictional Note
The legal meaning documented in Black's is exclusively Maryland-specific and historically bounded by the tobacco inspection regime challenged in Turner v. Maryland (1883). No other state developed a comparable charge under this name. The term carries no legal meaning outside that narrow context.
